Abstract

The Paracanthocobitis zonalternans species complex is revised based on analysis of morphological and molecular data. Three new speciesP. nigrolineataP. marmorata, and P. triangula are described, and P. phuketensis is removed from synonymy. All species are described morphologically, geographic ranges are delimited, and relationships are discussed for those for which molecular data (cytochrome c oxidase subunit 1 - COI) are available. In view of the morphological similarities of some of the species, a surprising result of this study was the moderately large genetic distances among species. Uncorrected COI p-distances between geographic clades of P. zonalternans ranged from 7.6–9.3%, suggesting that the species are reproductively isolated from one another even though morphological changes are minor. Paracanthocobitis phuketensis, distributed in several rivers draining to the Gulf of Thailand and to the Andaman Sea, shows considerable intraspecific variation that should be explored in detail for historical and ecological explanations. Cobitis chlorosoma McClelland, 1839 from Assam, India, is a synonym of P. botia, not P. zonalternans.

Atelopus subornatus  Werner, 1899


Abstract 

The Neotropical toads of the genus Atelopus are among the most imperiled of all amphibians (La Marca et al. 2005; Gonzalez-Maya et al. 2013; McCaffery et al. 2015). Nowadays, at least 90% of the 93 listed species are threatened and more than 77% are Critically Endangered (McCaffery et al. 2015; IUCN 2016). Colombia has 44 described species of Atelopus (Frost 2017), two of these are categorized as extinct (EX) by the IUCN (2016): A. ignescens and A. longirostris, although they were recently re-discovered in Ecuador (Tapia et al. 2017), 34 as critical endangered (CR), four as endangered (EN), two as vulnerable (VU), one species has data deficient (DD) and another one has not been evaluated. Atelopus subornatus Werner, 1899, is an endemic Colombian harlequin toad described from 2300 to 2800 m.a.s.l in the municipalities of Sibaté (Alto de Sibaté and Agua Bonita) and Fusagasuga (above Fusagasuga and Tierra Negra), in Cundinamarca (Fig. 1A), on the western flank from Cordillera Oriental of Colombia (Werner 1899; Lynch 1986; Lötters 1989, 1992). The last record of this species was in 1993 (Lötters 2005), and it currently is listed as Critically Endangered by the IUCN (2016). Herein, we report the rediscovery of A. subornatus at a new locality from Tolima, Colombia (Fig. 1A), and redescribe its tadpole. The determination of the species was based on comparisons with material deposited in the amphibian collection of the Instituto de Ciencias Naturales, Universidad Nacional de Colombia (ICN-UNAL) for all species of Atelopus reported from the same general area in Cundinamarca and relatively similar to A. subornatus. The specimens are housed in the Herpetological collection of the Tolima University (CZUT-A) and amphibian collection of ICN-UNAL.

Takydromus albomaculosus
Wang, Gong, Liu & Wang, 2017 


Abstract

Many early descriptions of species of the genus Takydromus were based on limited diagnostic characteristics. This has caused considerable challenges in accurate species identification, meaning that a number of cryptic species have been erroneously identified as known species, resulting in substantially underestimated species diversity. We have integrated evidence from morphology and DNA sequence data to describe a new species of the Asian Grass Lizard, Takydromus albomaculosus sp. nov., based on two specimens from Tianjingshan Forestry Station, Ruyuan County, Guangdong Province, China. The new species can be distinguished from other known Takydromus species by distinctive morphological differences and significant genetic divergence in the mitochondrial COI gene. Morphologically, the new species differs from the known 22 congeners in the following combination of characters: relatively large body size, SVL 70.9 mm in female, 65.5 mm in male; presence of three or four pairs of femoral pores and four pairs of chin-shields; supraoculars three, rarely four, the posterior loreal either in contact with the anteriormost supraocular or not; the presence of supraciliary granules; the presence of six rows of ventral scales, strongly keeled in the male, and smooth but with the outermost row keeled in the female; the presence of enlarged and keeled lateral scales in a row above the ventrals, but shorter than the ventrals; subdigital lamellae 23–24 under the fourth finger and 29–30 under the fourth toe; dorsal surface brown, ventral surface green, flank dark brown or brown black with several prominent white round spots; the presence of a pair of white longitudinal dorsolateral stripes and a pair of white longitudinal ventrolateral stripes. Takydromus albomaculosus sp. nov. represents the twenty-third species of this genus, of which six species occur in northern Guangdong, where the biodiversity level of Takydromus is the second highest in the world, just below that of Taiwan.

Takydromus albomaculosus sp. nov.

Etymology. The specific name “albomaculosus” refers to the “white round spots” on the flanks of body, which are the diagnostic features of this new species. We propose the standard English name “white spotted East Asian Grass Lizard”, and the Chinese name “Tianjingshan Cao Xi”.

Cirrhilabrus shutmani
Tea & Gill, 2017  


Abstract

Cirrhilabrus shutmani, new species, is described on the basis of four specimens from Didicas Volcano, Babuyan Islands, Cagayan province, northern Philippines. The holotype and three paratypes were collected at a depth of 50–70 m, along denuded rubble slopes. The new species belong to a complex consisting of Cirrhilabrus blatteus, C. claire, C. earlei, C. jordani, C. lanceolatus, C. roseafascia, C. rubrisquamis and C. sanguineus. Aside from similar nuptial male colouration, the nine species share the following character combination: relatively short pelvic fins (not or barely reaching anal-fin origin, except for C. claire with relatively long pelvic fins); a pair of stripes on head (in both sexes); and, dorsal and anal fins without obvious stripes or spots. It differs from the other members of its group in lacking any stripes on the upper and lower body, and in having the following live colouration details: upper part of nape dusky red; dorsal and anal fin bright red with dusky markings; pelvic fins bright red, dusky anteriorly; caudal fin bright yellow basally with distal half bright red. We also present new distribution records for C. claire, C. earlei and C. lanceolatus, as well as a brief mention of a possibly new, related species from the Ogasawara Islands.

Cirrhilabrus shutmani n. sp. 
Magma Fairy-wrasse

Diagnosis. Cirrhilabrus shutmani shares similar meristic counts to the other species in its complex, but differs from congeners in the following live colouration details: upper part of nape dusky red; dorsal and anal fin bright red with dusky markings; pelvic fins bright red, dusky, and unmarked; caudal fin bright yellow basally with distal half bright red.

Etymology. Named in honour of Barnett Paul Shutman, who first provided photos as well as the type specimens of the new species (via Aquarium Iwarna, Singapore). The common name, magma fairy wrasse, alludes to its live colouration, as well as the type location of Didicas Volcano, an active volcano part of the “Pacific Ring of Fire” at the southern end of the Luzon Volcanic Arc. 

Distribution and habitat. Cirrhilabrus shutmani is known only from the type locality, Didicas Volcano in the Babuyan Islands at the northern tip of the Philippines (Figure 6). It appears to inhabit steep slopes comprised mostly of volcanic rubble at depths ranging from 50–70 m

Gomphidictinus tongi 
Zhang, Guan & Wang, 2017


Abstract

A new gomphid species, named as Gomphidictinus tongi sp. nov. (Holotype male, Mt. Diaoluoshan, altitude 930m a.s.l., Lingshui County, Hainan Province, China) is described here. It is regarded as the third species of Gomphidictinus based on the presence of the basal spine on median segment of the penis organ. Gomphidia interruptistria Zha, Zhang & Zheng, 2005 is regarded as a junior synonym of Gomphidictinus perakensis (Laidlaw, 1902), which is recorded from Yunnan, China.

  Mansoa ventricosa A.H. Gentry

 Francisco & Lohmann, 2017

Abstract

Pachyptera ventricosa is a rare and poorly known species of liana that occurs in wet forests from the state of Pará, in Brazil. This species is characterized by features that are diagnostic of four genera within tribe Bignonieae: Mansoa, Martinella, Pachyptera, and Tanaecium. The currently recognized P. ventricosa was originally described in Mansoa, but subsequently transferred to Pachyptera based on morphological similarities. In this study, we use a combination of molecular and morphological data to evaluate the current placement of P. ventricosa. We conduct a broad scale molecular phylogenetic study based on 114 sequences of ndhF and PepC representing 112 taxa and members of all genera recognized in Bignonieae. In addition, we also conduct detailed morphological studies of selected characters. Our molecular phylogenetic study indicates that the currently recognized Pachyptera ventricosa is more closely related to members of Mansoa than to Pachyptera. New morphological data corroborates the molecular phylogenetic placement indicating that this species is indeed best placed within Mansoa. We here propose the reestablishment of Mansoa ventricosa, and show the detailed description for this species, along with new distribution information, and the first illustration for this taxon.

Mansoa ventricosa A.H. Gentry (1979 [1980]: 783). 
Pachyptera ventricosa (A.H. Gentry) L.G. Lohmann (2014: 456) 

Type:— BRAZIL. Pará: Along the Belém-Brasilia highway, km 345, 9 August 1956, B. Maguire et al. 56083 (holotype, MO-2232816!; isotypes, COL-110166 not seen, MG-136673, NY-328882!, US-3189002 image!).

Pollination:— The corolla morphology is classified as a variant of the Martinella type (Gentry 1974), and is likely associated with bat pollination (Alcantara & Lohmann 2010, Machado & Vogel 2004). This species shares tricolpate coarse reticulate pollen grains with Martinella obovata (Gentry & Tomb 1979) suggesting convergent evolution of pollen type. Such convergence has also been observed in other floral traits such as the purple colored flower, thick corolla texture, open mouth, and subexserted anthers. 

Distribution and habitat:— Mansoa ventricosa is endemic to Northeastern Brazil (Maranhão, Pará), where it occurs in wet evergreen forests (Figure 5). Prior to this work, this species was only known from the holotype collected in the Brazilian state of Pará, a paratype collected in the Brazilian state of Maranhão (G.T. Prance 58978; UB and NY), and one collection from 1980 (D.C. Daly 774; MG, MO, and NY). Two additional specimens were collected during our fieldwork in Pará, (Brazil), expanding the distribution of this species to Santarém and Belterra.

Taxonomic notes:— Mansoa ventricosa is easily recognized by a combination of cylindrical and striated branchlets with “V” shaped interpetiolar clusters of glands, subulate prophylls of the axillary buds, and leaflets with nectaries grouped at the base of the abaxial surface. Reproductive characters that can help in its identification are the thyrsoid inflorescences, calyx with patelliform glands clustered next to the margin, corolla campanulate, with tube light purple, densely puberulous outside, with patelliform glands at the upper portion of the apex tube, androecium subexserted with yellow anthers, and exserted gynoecium.

Eutherian mammals (Placentalia and all mammals phylogenetically closer to placentals than to marsupials) comprise the vast majority of extant Mammalia. Among these there is a phenomenal range of forms and sizes, but the origins of crown group placentals are obscure. They lie within the generally tiny mammals of the Mesozoic, represented for the most part by isolated teeth and jaws, and there is strongly conflicting evidence from phenomic and molecular data as to the date of origin of both Eutheria and Placentalia. The oldest purported eutherians are Juramaia from the Upper Jurassic of China, and Eomaia and Acristatherium from the Lower Cretaceous, also of China. Based on dental characters and analyses of other morphological and molecular data, doubt has recently been cast on the eutherian affinities of the Chinese taxa and consequently on the date of emergence of Eutheria. Until now, the only tribosphenic mammal recorded from the earliest Cretaceous (Berriasian) Purbeck Group of Britain was the stem tribosphenidan Tribactonodon. Here we document two new tribosphenic mammals from the Purbeck Group,Durlstotherium gen. nov. and Durlstodon gen. nov., showing highly derived eutherian molar characters that support the early emergence of this clade, prior to the Cretaceous.

Key words: Mammalia, Eutheria, dentition, Early Cretaceous, Purbeck Group, Britain.

Abstract

The Great evening bat Ia io Thomas, 1902, previously considered as an endemic to the Indochinese subregion, is reported from the Sundaic subregion for the first time based on specimens collected from three localities in Surat Thani Province and Phang Nga Province, peninsular Thailand. It is described herein as a new subspecies based on its substantially larger body and skull size. The mitochondrial COI and cytochrome b genes reveal that the new subspecies has a genetic distance of 1.89% and 1.65%, respectively, from the nominate subspecies. Echolocation calls comprise four harmonics, with the maximum energy in the first harmonic (fmaxe) of 23.6–27.4 kHz. Notes on the population size as well as roosting and foraging behaviour are also provided.

 Grotto Salamanders, Eurycea spelaea (Stejneger, 1892)


Abstract
The transition from carnivory to omnivory is poorly understood. The ability to feed at more than one trophic level theoretically increases an animal’s fitness in a novel environment. Because of the absence of light and photosynthesis, most subterranean ecosystems are characterized by very few trophic levels, such that food scarcity is a challenge in many subterranean habitats. One strategy against starvation is to expand diet breadth. Grotto Salamanders (Eurycea spelaea (Stejneger, 1892)) are known to ingest bat guano deliberately, challenging the general understanding that salamanders are strictly carnivorous. Here we tested the hypothesis that grotto salamanders have broadened their diet related to cave adaptation and found that, although coprophagous behavior is present, salamanders are unable to acquire sufficient nutrition from bat guano alone. Our results suggest that the coprophagic behavior has emerged prior to physiological or gut biome adaptations.

Abstract

For Jansen’s goatfish, Parupeneus jansenii (Mullidae), taxonomic knowledge has been rather poor and occurrence information restricted to a few localities only, with verified records from northern Sulawesi and Sunda Street (Indonesia), and Luzon (Philippines). This species is here included in the so-called “heptacanthus” group together with the Indo-Pacific cinnabar goatfish, P. heptacanthus, and five Indian Ocean congenerics, based on an evenly, symmetrically rounded posterior maxilla margin and similarities in meristic characters and preserved colour. In total 29 P. jansenii and 53 P. heptacanthus consisting of types, recently collected material from south-central Vietnam, southern Indonesia, and NE Australia, and geographically related reference material were studied along with single types of the other five heptacanthus-group species and P. angulatus, a morphologically similar Western Indian Ocean species. In total 62 quantitative meristic and morphometric characters including standard length (SL) were analysed after splitting the data into two size classes (small-sized fish, < 110 mm SL, vs. large-sized fish  > 110 mm SL) to account for size-related differences due to allometry. Diagnoses for P. jansenii and P. heptacanthus and a redescription for P. jansenii were prepared. Fresh-fish colour descriptions for both large- and small-sized voucher specimens of P. jansenii are provided and the effects of freshness status on colour patterns is documented. New records for P. jansenii for Vietnam, southern Indonesia and NE Australia (= first verified record for Australia) are reported and depth information (24–100 m depth range) is given for the first time. P. jansenii differs from the co-occurring P. heptacanthus - independently of size - in shallower body and caudal peduncle, smaller maximum head depth, shorter barbels, caudal and pelvic fins, shallower first dorsal fin, shallower first ray of second dorsal fin, and lack of small dark red or reddish-brown spot on or just below the eighth lateral-line scale. The populations of P. jansenii from Vietnam and Australia differ from each other in a single character, the height of the eighth dorsal-fin ray, but both overlap with the intermediate population from Indonesia. This comprehensive alpha-taxonomic approach provides a useful tool for uncovering the diversity of Parupeneus goatfishes.

Spinosaurid cranial remains from Brazil.
Sales & Schultz, 2017 

Abstract

Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of IrritatorAngaturama, and Oxalaia. In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary issues concerning this particular clade of dinosaurs. The mesial-most tooth of the left maxilla of the holotype of Irritator is regarded as representing the third tooth position, which is also preserved in the holotype of Angaturama. Thus, both specimens cannot belong to the same individual, contrary to previous assumptions, although they could have been the same taxon. In addition, the position of the external nares of Irritator is more comparable to those of Baryonyx and Suchomimus instead of other spinosaurine spinosaurids. In fact, with regards to some craniodental features, Brazilian taxa represent intermediate conditions between Baryonychinae and Spinosaurinae. Such a scenario is corroborated by our cladistic results, which also leave open the possibility of the former subfamily being non-monophyletic. Furthermore, the differences between spinosaurids regarding the position and size of the external nares might be related to distinct feeding habits and degrees of reliance on olfaction. Other issues concerning the evolution and taxonomy of Spinosauridae require descriptions of additional material for their clarification.

Final remarks
Spinosaurid dinosaurs have been surrounded by an enigmatic atmosphere due to their bizarre anatomy and morphology as well as the fragmentary nature of most collected specimens. The tragic loss of the holotype of Spinosaurus aegyptiacus also contributed to this condition. Despite being incomplete, spinosaurid cranial remains from Brazil are informative in multiple ways and help fill in some gaps in the knowledge on these theropods. The reinterpretation of certain craniodental features supports, for example, the distinction between Irritator and Angaturama at least at the individual level, and our cladistic results indicate the latter taxon and Oxalaia as successive outgroups of MSNM V4047. In addition, the evolution of spinosaurid craniodental features is likely related to different trends towards semiaquatic and/or piscivorous habits. These trends might have had a major impact on the position and size of the external nares, suggesting the reduction of the importance of olfaction in relation to other senses during foraging. However, other issues remain more disputable, such as the possible non-monophyly of Baryonychinae, the possible synonymy between the Araripe spinosaurids, and the sequence of morphological changes during the evolutionary history of Spinosauridae. Further study is needed to address these issues, including the formal description of additional cranial and postcranial remains. In this sense, although African materials are usually the focus of most investigations, Brazilian specimens play an important role in discussions concerning the evolution and paleobiology of Spinosauridae. This statement is clearly corroborated by new findings of these dinosaurs in understudied fossil sites.

Phrynopus inti 
Lehr, von May, Moravec & Cusi, 2017

Abstract
We describe a new species of Phrynopus from the upper montane forests and high Andean grasslands (puna) of the Pui Pui Protected Forest and its close surroundings (Región Junín, central Peru) and compare it morphologically and genetically with other species of Phrynopus.
Phrynopus inti sp. n. is known from four localities outside and two localities inside the Pui Pui Protected Forest between 3350 and 3890 m a.s.l. Studied specimens of the new species are characterized by a snout-vent length of 27.2–35.2 mm in males (n = 6), and 40.4 mm in a single female, by having the skin on dorsum and flanks smooth with scattered tubercles, venter smooth, by lacking a tympanum, and males without vocal slits and nuptial pads. In life, the dorsum is pale grayish brown with or without dark brown blotches, or dorsum blackish brown with small yellow flecks, throat, chest and venter are pale grayish brown with salmon mottling, groin is pale grayish brown with salmon colored flecks, and the iris is golden orange with fine dark brown reticulations. The new species is morphologically most similar to Phrynopus kauneorum and P. juninensis. For the latter we describe the coloration in life for a specimen obtained at the type locality. A molecular phylogenetic analysis based on mitochondrial and nuclear DNA sequences inferred that the new species is most closely related to Phrynopus kauneorumPmiroslawaeP. tautzorum, and an undescribed species distributed at high elevation in Región Pasco, central Peru.

Abstract  

We describe a new species, Fejervarya muangkanensis sp. nov., based on a series of specimens collected from Ban Tha Khanun, Thong Pha Phum District, Kanchanaburi Province, Thailand. The new species is easily distinguished from its congeners by morphological and molecular data, and can be diagnosed by the following characters: (1) small size (adult male snout-vent length (SVL) 33.5 mm; female SVL 40.0–40.9 mm); (2) tympanum small, discernible but unclear; (3) poorly developed toe webbing; (4) no lateral line system in adults; (5) characteristic “Fejervaryan” lines present in females; and (6) femoral glands absent. Molecular phylogenetic analysis of mitochondrial 16S rRNA further supports it as a distinct lineage and distinguishes it from its congeners for which sequences are available.

Fejervarya muangkanensis 

Etymology: The specific epithet muangkanensis is derived from the common name of the Kanchanaburi province, Thailand. 
Suggested common names:  Kanchanaburi Rain-Pool Frog. 

Ecology: The species is found in small swamps in secondary forests at elevations between 700–900 m a.s.l. Advertisement calls of the males can be heard in small ponds from July to September in Thong Pha Phum, Kanchanaburi Province. Calling males are usually observed within or beside the swamp (Figure 6). 

Distribution: This species is currently known only from Thong Pha Phum, Kanchanaburi Province, western Thailand (Figure 1). 

DISCUSSION 
Although our discovery of F. muangkanensis increases the total number of Fejervarya species of Thailand to nine (Suwannapoom et al., 2016), the diversity of this group may still be underestimated. For example, previous molecular studies have identified several distinct lineages diverged from closely related, recognized species, including Fejervarya sp. hp3 from Pilok, Thailand, and Fejervarya sp. hp2 from Bangkok, Thailand (Kotaki et al., 2010). Future studies should examine morphological characteristics of specimens from these regions in detail to confirm their taxonomic identities. Moreover, as many areas of Thailand are still poorly or never surveyed for amphibian diversity, especially in southern Thailand, unrecognized diversity of the genus could still exist. Closer inspections of previously collected congeners from these regions are necessary to better understand amphibian diversity in Thailand, which could help to manage and conserve this unique diversity effectively.

Red-thighed Horned Frog || DOI:  10.11646/zootaxa.4344.3.3 

Abstract

The Asian frog genus Megophrys is a diverse group of morphologically conserved, forest-dwelling frogs. The genus harbours highly localised species diversification and new species continue to be described on a regular basis. We examined the taxonomic status of a population of Megophrys frogs from the Hoang Lien Range in northern Vietnam and southern China previously identified as M. kuatunensis (subgenus Panophrys). Preliminary phylogenetic analyses using a fragment of 16S rDNA places the species in question within the Megophrys (subgenus Panophrys) species group, a primarily Chinese radiation within the genus. On the basis of morphological, molecular and bioacoustic data, we conclude that this population does not represent M. kuatunensis, or any known species in the genus. We herein describe this species of Megophrys as new. Known only from Sa Pa District, Lao Cai Province in Vietnam and Jinping County, Yunnan Province in China, the new species is likely to be threatened by ongoing deforestation in the region. We provide an updated species description of Mkuatunensis based on type specimens, and suggest that M. kuatunensis is likely to be restricted to eastern China.

The “Lembeh Frogfish” or “Ocellated Frogfish,” a distinct antennariid, known for many years, especially among members of the dive community, and suggested by some to represent an undescribed species, is identified as Nudiantennarius subteres (Smith and Radcliffe). Unique in several ways—including reduced dermal spinules, the body appearing naked; illicium short, about half the length of the second dorsal-fin spine; second dorsal-fin spine unusually long and narrow, without a posterior membrane; pectoral lobe narrow, somewhat detached from the body; membranes between the rays of the paired fins deeply incised; and all pelvic-fin rays simple—the species is redescribed and figured below. Morphological and molecular analyses indicate a close relationship with the Sargassumfish, Histrio histrio.

Abstract

Centrophorus specimens with a distinctive long-based first dorsal fin (long-finned species) have previously been considered to be Centrophorus lusitanicus first described from Portugal. Critical examination of the original description and illustration reveal that C. lusitanicus should be considered a junior synonym of C. granulosus. However, the specimen considered to be the syntype of C. lusitanicus in the Natural History Museum in London is clearly a long-finned species and not conspecific with C. granulosus. A more detailed investigation revealed that this specimen should not be considered a syntype and was likely not originally collected off the coast of Portugal. Investigation of long-finned specimens of Centrophorus from the Indo-West Pacific and Eastern Atlantic revealed that two undescribed species exist and are herein formally described as Centrophorus leslieiandC.longipinnis. The two species are similar morphologically and belong to the long-snout Centrophorus group (e.g. C. isodon and C. harrissoni) but are clearly separable based on their very long first dorsal fins. The two species differ in relative length of the first dorsal fin and several other characters. They also differ genetically. Nonmetric multidimensional ordination based on morphometric data reveals both species level and ontogenetic differences. A short erratum is also provided for Part 1 of this revision of the Centrophorus due to two figure related errors which may cause some confusion.

Centrophorus longipinnis n. sp.
Longfin Gulper Shark

 Etymology. Specific name a combination of the Latin longus (long) and pinna (fin) in allusion to the very distinctive long-based first dorsal fin this species possesses.

Distribution. Type material from off Taiwan (Cheng-gong and Da-xi fish landing sites—local fishing grounds), Indonesia (off southwest Java and eastern Lombok), and Papua New Guinea (Huon Gulf) (Fig. 10). Compagno et al. (2005) reported this species off Puerto Princesa City in the Philippines (JPAG 226, tissue accession GN4348); differed slightly in ND2 sequence and specimen not examined in this study. Limited depth information available as most specimens collected from fish landing sites; caught from depths of 330–460 m in Papua New Guinea (P. Neira, pers. comm.).


Centrophorus lesliei n. sp.
African Gulper Shark

Etymology. Named after Dr Robin Leslie (Fisheries Branch, Department of Agriculture, Forestry and Fisheries in South Africa) who has contributed greatly to our knowledge of southern African chondrichthyans and provided numerous important specimens and tissue samples for various projects.

Distribution. Type specimens were from the Mozambique Channel (Madagascar and Mozambique), and off Senegal, Côte d’Ivoire, Equatorial Guinea, and Togo at depths of 340– 500 m. The BMNH and ZMB specimens were most likely collected by Anchieta from Angola or Mozambique in the 1800’s. Additional specimens examined by Munoz-Chapuli & Ramos (1989) were recorded as being collected from Morocco, the Canary Islands, and Ghana at depths of 370– 610 m.

Abstract  

Background
The colubrid snakes of the genus Rhynchocalamus are seldom studied and knowledge of their ecology and life history is scarce. Three species of Rhynchocalamus are currently recognized, R. satunini (from Turkey eastwards to Iran), R. arabicus (Yemen and Oman), and R. melanocephalus (from the Sinai Peninsula northwards to Turkey). All are slender, secretive, mainly nocturnal and rare fossorial snakes. This comprehensive study is the first to sample all known Rhynchocalamus species in order to review the intra-generic phylogenetic relationships and historical biogeography of the genus.

Methods
We revised the systematics of Rhynchocalamus using an integrative approach and evaluated its phylogeography. The phylogenetic position within the Colubridae and the phylogenetic relationships within the genus were inferred using 29 individuals belonging to the three known species, with additional sampling of two other closely-related genera, Muhtarophis and Lytorhynchus. We analysed three mitochondrial (12S, 16S, cytb) and one nuclear (c-mos) gene fragments. Phylogenetic trees were reconstructed using maximum likelihood and Bayesian inference methods; the latter method also used to provide the first time-calibrated molecular phylogeny of the genus. We generated a nuclear network and carried out a topology test and species delimitation analysis. Morphological comparisons were used to differentiate among species and to describe a new species from Israel. The studied material was comprised of 108 alcohol-preserved specimens, 15 photographs, and data from the literature for the examination of 17 mensural, 14 meristic, and two categorical characters.

Results
The molecular results support Rhynchocalamus as monophyletic, and as having split from its sister genus Lytorhynchus during the Late Oligocene. The three recognized species of Rhynchocalamus comprise four independently evolving groups. The molecular results reveal that the genus began to diverge during the Middle Miocene. We revealed that the best-studied species, R. melanocephalus, is paraphyletic. A population, formally ascribed to this species, from the Negev Mountain area in southern Israel is phylogenetically closer to R. arabicus from Oman than to the northern populations of the species from Israel, Syria and Turkey. Herein we describe this population as a new species: Rhynchocalamus dayanae sp. nov.

Discussion
We identify four species within RhynchocalamusR. satunini, R. arabicus, R. melanocephalus, and R. dayanae sp. nov., the latter, to the best of our knowledge, is endemic to southern Israel. The onset of Rhynchocalamus diversification is very old and estimated to have occurred during the Middle Miocene, possibly originating in the Levant region. Radiation probably resulted from vicariance and dispersal events caused by continuous geological instability, sea-level fluctuations and climatic changes within the Levant region.

Etymology. The specific epithet, “dayanae,” is named in honour of Professor Tamar Dayan, director of the Steinhardt Museum of Natural History at Tel Aviv University and curator of the Terrestrial Vertebrate Collection. This naming of the new species constitutes a special recognition of Professor Dayan by two of her former students (KT and SM) to acknowledge her immense contribution to the conservation of Israeli fauna, and her efforts in establishing the National Natural History Museum at Tel Aviv University, and in promoting taxonomy, conservation and ecology studies in Israel.

Lavocatchampsa sigogneaurusselae
Martin  & de Lapparent de Broin. 2016


Abstract
Notosuchians from Cretaceous continental environments of Gondwana have developed an unexpected array of morphologies comparable to mammals and their extinct relatives. However, this exceptional diversity is unbalanced, with South America holding nearly three times the generic diversity of Africa-Madagascar. With the exception of the triconodonts and of a very specialized group, the Gondwanatheria, in none of these landmasses do mammals dominate, and as a result, the low notosuchian diversity in Africa-Madagascar appears to be an artifact of sampling. Here, we describe a new miniature notosuchian from the Albian-Cenomanian Kem-Kem Beds of Morocco filling this gap. Lavocatchampsa sigogneaurusselae, gen. et sp. nov., exhibits a new type of heterodonty with absence of maxillary and dentary caniniform dentitions and teeth that gradually become massive posteriorly, and possess a sharp elongate median carina flanked by two multicusped cingula. The occlusion pattern is revealed by computed tomography and scanning electron microscopy (SEM) and shows that the main component of jaw closure is vertical, and not horizontal as has been proposed in closely related forms. Phylogenetic analysis recovers the new taxon as part of a basal stock of Gondwanan ziphosuchians with close affinities to Candidodon itapecuruense, Malawisuchus mwakasyungutiensis, and Pakasuchus kapilimai. We revise the diagnosis of Candidodontidae, a clade characterized by a particular heterodont dentition recalling that of triconodont mammals. The recognition of this new clade confirms previous hypotheses of a vicariant vertebrate assemblage present on a continuous South American–African landmass.
