Abstract

Sorbus cibagouensis sp. nov. (Rosaceae subfam. Rosaceae), a new taxon from Cibagou National Nature Reserve, Zayü County, southeastern Xizang (Tibet), China, is described and illustrated. It is related to S. monbeigii (Cardot) Balakr., but primarily differs in the number of styles (S. cibagouensis = 5; S. monbeigii = 4) and the shape of stipules and leaves (S. cibagouensis: stipules caducous, small, with entire margin, leaflets in 9–11 pairs; S. monbeigii: stipules persistent, large, serrate, leaflets in 6–8 (–10) pairs).

Abstract
The globally threatened Straw-headed Bulbul Pycnonotus zeylanicus is one of South-East Asia’s most imperiled songbirds due to the surging demand for the species in the regional bird trade. Recently uplisted from Vulnerable to Endangered, populations of the Straw-headed Bulbul have been extirpated from Java, Thailand and possibly Sumatra while those in Borneo and Peninsular Malaysia are in decline. Intriguingly, a significant yet rarely documented population of this species persists in Singapore. A major stronghold in Singapore is Ubin Island where a population is known since the 1920s. Using a long-term citizen science dataset rarely available for South-East Asian bird species, we determined the status and population trends of the Straw-headed Bulbul in Singapore over a 10–15 year period using Poisson regression models and standardised population indices. We found that the Straw-headed Bulbul population has increased at a rate of 3.69 ± 1.21% per annum on Ubin Island, while the population on Singapore Island remained stable (0.56% per annum) from 2000 to 2016. The population trends in Singapore contrast starkly with the declines reported elsewhere in South-East Asia. We estimated the population in Singapore to be a minimum of 202 individuals, distributed over multiple forest patches. The largest subpopulation of about 110 adult individuals persists on Ubin and which alone forms between 6.5–18.3% of the estimated global population in 2016. Given this unique situation, we recommend a number of conservation measures for the Straw-headed Bulbul to better protect the species, including: (1) an expansion of the protected area network in Singapore to include Ubin as a reserve, (2) the development of an endangered species management plan and, (3) the establishment of ex-situ conservation programmes in zoological institutions and wildlife centres in the region.

Abstract

A new species of freshwater crab of the genus Sudanonautes Bott, 1955, is described from the tropical rainforests of Edea and Tiko in southern Cameroon, Central Africa. Sudanonautes tiko n. sp. is recognized by a unique combination of characters of the carapace, thoracic sternum, chelipeds, and male first gonopod, and by distinct mtDNA sequences for two loci (COI and 16S rRNA). A diagnosis, illustrations, and a tree of phylogenetic relationships based on mtDNA sequences are provided, along with a comparison to similar species from the region. Brief notes are provided on the ecology of the new species and of three other species of Sudanonautes collected during this study.

Scytalopus alvarezlopezi 
 Stiles, Laverde& Cadena, 2017

Tatamá Tapaculo |  DOI:  10.1642/AUK-16-205.1  

ABSTRACT
We describe Scytalopus alvarezlopezi from the Western Andes of Colombia. The new species forms part of a distinctive clade of Scytalopus tapaculos (Rhinocryptidae) that also includes S. robbinsi from Ecuador and S. stilesi and S. rodriguezi, which occur on the Central and Eastern Andes of Colombia. S. alvarezlopezi is easily diagnosable from its near relatives by its song and mitochondrial DNA; differences in plumage exist but are more subtle. The species inhabits dense understory vegetation on the floors and lower slopes of ravines in cloud forest at elevations of 1,300 to 2,100 m. On the Pacific slope, its altitudinal distribution is sandwiched between those of S. chocoensis (below) and S. vicinior (above); the latter in turn is replaced higher up by S. spillmanni and S. latrans, but S. alvarezlopezi also occurs at ∼2,000–2,100 m on eastern slopes just below the low ridgeline. All of the latter species are distinguished by vocal and plumage characters. Marked sexual differences in plumage exist in stilesi, but females have yet to be collected for alvarezlopezi and rodriguezi. We consider that S. alvarezlopezi is not threatened at present, but could be potentially vulnerable due to its restricted distribution; it is endemic to Colombia.

Etymology. We take pleasure in naming this species in honor of Humberto Alvarez-López, the ‘‘dean of Colombian ornithology,’’ for his many contributions to the knowledge and study of this country’s birds over nearly half a century. Humberto was professor of ornithology at the Universidad del Valle for nearly 4 decades and helped train several of Colombia’s foremost ornithologists and conservationists; in 1979 he founded in Cali the first local ornithological society in Colombia, an example soon followed by other cities in the country, and long edited and wrote for its journal. His book Introducción a las Aves de Colombia, published in 1979, was instrumental in making the observation of birds accessible to students and the public at large in Colombia, and arguably spearheaded the development of field ornithology in the country. In 1987 Humberto was president of the third Neotropical Ornithological Congress, the only one to be held in Colombia. He painstakingly translated Hilty’s monumental Guide to the Birds of Colombia into Spanish and was a founding member of the Asociación Colombiana de Ornitología, serving for more than 10 years as president and member of its governing body, where his sage advice on difficult matters often has been decisive. ¡Muchas gracias, ‘‘Maestro’’! 

We suggest the English name of Tatamá  Tapaculo for S. alvarezlopezi because the majority of localities for this species are in the middle sector of the Western Andes near the border between Risaralda and Choco Departments, in ´ which the most prominent and best-known mountain is Cerro Tatamá, the center of Tatama´ National Park; Cerro Montezuma is in the park’s buffer zone, Pisones is also within ~7 km of the park boundary, and CDC and OLR have found this species in several sites within the park itself.

RESUMEN: Describimos Scytalopus alvarezlopezi de la cordillera Occidental de los Andes colombianos. Esta nueva especie forma parte de un clado bien definido de tapaculos del género Scytalopus (Rhinocryptidae) que también incluye a S. robbinsi de Ecuador y S. stilesi y S. rodriguezi, las cuales están presentes en las cordilleras Central y Oriental de los Andes colombianos. S. alvarezlopezi es fácilmente diagnosticable en comparación con sus parientes por sus vocalizaciones y ADN mitocontrial; también hay diferencias en plumaje pero son más sutiles. La especie habita en el sotobosque denso de los fondos y lados de barrancos en bosque nuboso entre elevaciones de 1,300 y 2,100 m. Sobre la vertiente del Pacífico, la distribución altitudinal de alvarezlopezi está entre las de chocoensis (hacia abajo) y vicinior (hacia arriba); más arriba, vicinior es reemplazado por spillmanni y S. latrans; sin embargo, alvarezlopezi alcanza localmente elevaciones de 2,100 m o más sobre la vertiente oriental de algunos filos bajos justo por debajo de la cima. Todas estas especies se distinguen por vocalizaciones y plumaje. Existen differencias en plumaje entre los sexos de stilesi, pero aun falta recolectar hembras de rodriguezi y alvarezlopezi. Consideramos que actualmente S. alvarezlopezi no está amenazado, pero debido a su distribución restringida, potencialmente podría considerarse vulnerable; es una especie endémica a Colombia.

Diaphenchelys dalmatian  
Hibino, Satapoomin & Kimura, 2017


Abstract
A new species of moray eel, Diaphenchelys dalmatian is described based on five specimens [289.8–503.0 mm total length (TL)] collected from the western coast of peninsular Thailand and the Gulf of Thailand. It can be easily distinguished from Diaphenchelys pelonates McCosker and Randall 2007, another species of the genus Diaphenchelys McCosker and Randall 2007, by its coloration (ground color white with brown dalmatian-like spots vs. brown with pale vermiculate pattern). The present new species also differs from D. pelonates in its longer tail (62.0–64.6% TL vs. 59.6–61.5%), fewer infraorbital pores along upper lip (three vs. four), fewer mandibular pores (five vs. six or seven), and fewer vertebral counts (preanal vertebrae 43–46 vs. 55–58; total 126–131 vs. 153–155). Diaphenchelys is closely similar to the genus Strophidon McClelland 1844 in the shape of neurocranium, the elongate body, low vertical fins, eye location, jaw shape, and presence of inner mandibular teeth. However, both differ in the vertebral counts (126–155 in Diaphenchelys vs. 164–208 in Strophidon) and coloration (prominent pattern vs. uniform).

Diagnosis. A species of Diaphenchelys with the following combination of characters: tail 62.0–64.6% TL; three infraorbital pores along upper lip; five mandibular pores; ground color of body white, with numerous brown dalmatian-like spots dorsolaterally; predorsal vertebrae 6–9, preanal vertebrae 43–46 and total 126–131; MVF 7-45-128.


Distribution and ecological note. Known from the western coast of peninsular Thailand (Andaman Sea, marginal sea of the northeastern Indian Ocean) and the Gulf of Thailand. Although the collecting depth and environment of the present specimens are unclear, the holotype is strongly considered to be from the muddy bottom <100 m depth because it was collected with Gymnothorax mccoskeri Smith and Böhlke 1997, Ophichthus cephalozona (Bleeker 1864), Muraenesox cinereus (Forsskål 1775), and some apogonid and leiognathid fishes generally collected from shallow coastal water (Smith and Böhlke 1997; Allen and Erdmann 2012; Kimura 2013; Shibukawa 2013).

Etymology. The scientific name, dalmatian, is a noun in apposition, representing its similar appearance to that breed of speckled dog.

Abstract

The Chinese species of Pediobius Walker, 1846 are treated in this paper, resulting in 34 species, of which 5 are newly described: P. bisulcatus Cao & Zhu sp. n., P. elongatus Cao & Zhu sp. n., P. petiolapilus Cao & Zhu sp. n., P. prominentis Cao & Zhu, sp. n., and P. tortricida Cao & Zhu, sp. n. Nine species are also newly recorded from China: P. anomalus (Gahan, 1920), P. bethylicidus Kerrich, 1973, P. bruchicida (Rondani, 1872), P. cassidae Erdös, 1958, P. claviger (Thomson, 1878), P. erionotae Kerrich, 1973, P. phragmitis Bouček, 1965, P. saulius (Walker, 1839), and P. tetratomus (Thomson, 1878). Four new synonyms are proposed: P. illiberidis Liao, 1987 under P. pyrgo (Walker, 1839) syn. n., P. planiceps Sheng & Kamijo, 1992 under P. inexpectatus Kerrich, 1973 syn. n., P. sinensis Sheng & Wang, 1994 under P. facialis (Giraud, 1863) syn. n., and P. songshaominus Liao, 1987 under P. yunanensis Liao, 1987 syn. n. The species-group concept is used to compare similar species, of which eight are recognized in China including two newly recognized groups: the cassidae-group and the crassicornis-group. One species complex, the P. eubius complex, is also recognized. An updated checklist of the Chinese species of Pediobius is provided, with species-group placement. New host records for Pediobius species from China are summarized in a table and valid species possibly present in China but not included in this study in another table. A key to all known females and males of Chinese Pediobius is also provided.

Platychelys oberndorferi Wagner, 1853

Artwork by P. Röschli. DOI:  10.1038/srep42376 

Abstract
Modern turtles are composed of two monophyletic groups, notably diagnosed by divergent neck retraction mechanisms. Pleurodires (side-necked turtles) bend their neck sideways and protect their head under the anterior margin of the carapace. Cryptodires (hidden-necked turtles) withdraw their neck and head in the vertical plane between the shoulder girdles. These two mechanisms of neck retraction appeared independently in the two lineages and are usually assumed to have evolved for protective reasons. Here we describe the neck of Platychelys oberndorferi, a Late Jurassic early stem pleurodire, and find remarkable convergent morphological and functional similarities with modern cryptodires. Partial vertical neck retraction in this taxon is interpreted to have enabled fast forward projection of the head during underwater prey capture and offers a likely explanation to the functional origin of neck retraction in modern cryptodires. Complete head withdrawal for protection may therefore have resulted from an exaptation in that group.

Abstract

Pristimantis, distributed throughout the New World tropics, is the most speciose vertebrate genus. Pristimantis presents an enormous morphological diversity and is currently divided into several demonstrably non-monophyletic phenetic species groups. With the purpose of increasing our understanding of Pristimantis systematics, we present the first phylogenetic analysis using molecular evidence to test the monophyly and infer evolutionary relationships within the Pristimantisleptolophus group, an endemic group of frogs from the highlands of the Colombian Andes. Our phylogenetic reconstruction recovers the group as monophyletic with high support, indicating general concordance between molecular data and morphological data. In addition, we describe a new polymorphic species lacking conspicuous tubercles, a regular attribute among species of the P. leptolophus species group and endemic from the Páramo de Sonsón complex (Antioquia, Colombia). The phylogenetic position of the new species is inferred and other systematic implications in the light of our results are discussed.

Abstract
Laos has large areas of primary forest with a largely unexplored fauna. This is evidenced by millipedes, class Diplopoda, with fewer than 60 species being recorded from the country. In the widespread Southeast Asian “Star Millipede” genus Eutrichodesmus Silvestri, 1910 (family Haplodesmidae), only two of 49 recorded species have been found in Laos. Four new species of Star Millipedes are here described from caves in Laos: Eutrichodesmus steineri Liu & Wesener, sp. n.E. deporatus Liu & Wesener, sp. n., Eparaster Liu & Wesener, sp. n. and Eparvus Liu & Wesener, sp. n.. A fifth species, for which only a female is available, remains unnamed. The defensive glands (ozopores) are found to be strongly or entirely suppressed in two of the new species, E. deporatus Liu & Wesener, sp. n. and E. paraster Liu & Wesener, sp. n., both troglobionts, which is new to the family. All of the Star Millipedes were collected during Northern Lao-European Cave Project faunal surveys conducted by the Senckenberg Museum, Frankfurt. A key to the six species of Eutrichodesmus currently known to occur in Laos is provided.

Abstract

A new species, Brownlowia latifiana (Malvaceae-Brownlowioideae), endemic to Terengganu, Peninsular Malaysia, is described and illustrated. This new species has most of its morphological characters that are related to those of the genus Jarandersonia. Therefore, a standard morphological taxonomic revision and morphometric analysis were carried out to assess the status of Brownlowia latifiana. Results of the morphometric analysis based on morphological characters showed that Brownlowia latifiana is embedded within the clades of Brownlowia but distanced from the clades Jarandersonia. Brownlowia formed a distinct clade in the clustering tree well separated from the Jarandersonia. A distribution map and a conservation assessment using the IUCN Red List categories and criteria are provided.

Brownlowia latifiana R.C.K.Chung, sp. nov. 
Type:— PENINSULAR MALAYSIA. Terengganu: Dungun, Jerangau Forest Reserve, buffer zone by the stream of Compartment 95, 65 m altitude, 21 July 2009 (flowers and fruits), Y.C. Chan & C.L. Lim FRI 65055 (holotype KEP [barcode 246218]; isotypes A, K). 

Brownlowia latifiana is closely related to B. argentata and B. tersa in leaf texture, type of indumentum and other flower and fruit characters. However, the former differs from the latter, B. argentata and B. tersa, by its narrowly elliptic leaves (vs. ovate to broadly ovate or lanceolate), glabrous beneath (vs. densely covered with scales), 10−20 pairs lateral veins (vs. 4−10), large transversely ellipsoid fruits (vs. small depressed obovoid), absence of androgynophore (vs. presence and elongated to 6 mm long, 3 mm thick), persistent calyx lobes (vs. absent), and thick fruit stalk (vs. thin stalk). The main morphological differences between these three species are shown in Table 3.

.....

Etymology:— This species is named after the current Director-General of Forest Research Institute Malaysia (FRIM), Dato’ Dr Abd. Latif bin Mohmod, for his contributions in securing fund of RM7.6 million for the Project of Safeguarding the Forest Plant Diversity of Peninsular Malaysia under the Ninth Malaysian Plan; successfully in acquiring the ownership of FRIM land area of 544.3 ha from the Selangor State Government in 2007; and in obtaining the recognition for FRIM as the Natural Heritage Site in 2009 and the National Heritage in 2012. 

Distribution and habitat:— This species is endemic to Peninsular Malaysia, known from Jerangau Forest Reserve and Sg. Jerangau in Dungun, Terengganu. It occurs in undulating and riverine areas of lowland dipterocarp forest on clay sandy and alluvial soils at about 65 m elevation.

Abstract:
We describe a new genus and two new species of toads from the Sumatran volcanoes Gunung Sorikmarapi and G. Kunyit, in the provinces of Sumatera Utara and Jambi, respectively. The new taxa can be distinguished from other genera, and each other, based on genetic differentiation, morphology, and advertisement call structure. We employ both nuclear and mitochondrial data to provide a phylogenetic hypothesis of relationships for the bufonid genera of the Sunda Shelf. While broadly corroborating previous studies, our results also shed light on the phylogenetic position of Pseudobufo. The new genus, Duttaphrynus, and Pseudobufo are basal to other Sunda Shelf genera in our phylogenies.

Keywords: Barisan Range, Bufonidae, Molecular phylogenetics, Sunda Shelf, Taxonomy


Sigalegalephrynus gen. nov. 
Type species.— Sigalegalephrynusmandailinguensis  by present designation.

Etymology.— The generic name is derived from the name given by the indigenous Batak people of the Toba region in Sumatera Utara to life-sized wooden puppets called Sigale Gale. These puppets are used during the papurpur sepata funerary festivals to placate the spirits of the dead who have left no children behind. The suffix is derived from the masculine and Latinized Greek noun for toad, phrynos. The new genus, with a relatively large size compared with most arboreal toads in the region, lanky hands, and a wood-brown complexion, is evocative of the Sigale Gale.

Common name.— Puppet Toads.

Content.— Our phylogenetic analyses indicate the presence of two species within the new genus: S. mandailinguensis Smart et al.; and S. minangkabauensis Smart et al.

Vegasaurus molyi 
O'Gorman, Salgado, Olivero & Marenssi, 2015  


ABSTRACT
A new elasmosaurid, Vegasaurus molyi, gen. et sp. nov., from Vega Island, James Ross Archipelago, Antarctica, is described. The holotype and only specimen of this species (MLP 93-I-5-1) was collected from the lower Maastrichtian Cape Lamb Member of the Snow Hill Island Formation. Vegasaurus molyi is the only Antarctic elasmosaurid and one of only a few Late Cretaceous elasmosaurids from the Southern Hemisphere whose postcranial anatomy is well known. Vegasaurus molyi is distinguished from other elasmosaurids by the following combination of characters: cervical region with 54 vertebrae with elongated centra, dumbbell-shaped articular faces and lateral ridge present in the anterior and middle parts of the neck but absent in the posterior-most cervical vertebrae; scapula with ventral ramus bearing a strong ridge in the anteromedial corner of its dorsal surface; ilium shaft with expanded distal end, divided into two parts forming an angle of 140 opening anteriorly; and humerus with anterior knee and prominent posterior projection with accessory posterior articular facet. Preliminary phylogenetic analysis places V. molyi within a clade that includes the Late Cretaceous Wedellian aristonectine elasmosaurids, Aristonectes and Kaiwhekea. This indicates a close relationship between Aristonectinae and non-Aristonectinae Late Cretaceous Weddellian elasmosaurids and suggests a Weddellian origin for the Aristonectinae

Abstract

The new, small cavernicolous species Helmablatta louisrothi gen. et sp. n. (Nocticolidae) from the Tan-Phu cave (Vietnam) is one of the most morphologically interesting cockroaches. The extremely modified upstanding tergal gland composite from three tergites and may serve for gripping the female head during copulation. This presumption is supported by the presence of a central big hook on tergite 8. Furthermore, both wing pairs are uncommonly adapted to help releasing sex pheromones without raising the wings. Histone 3 DNA-based maximum likelihood analyses indicate a recent origin and close phylogenetic relationship between Nocticola spp. and Helmablatta sp.—consistent with the Quaternary age of the source lava tubes.

Keywords: Blattaria, cave, lava tube, tergal gland

Helmablatta Vidlička, Vršanský et Deharveng, gen. n. 
Etymology. Helmablatta after the shape of tergal gland, suggesting helmet (Slavic “helma”) and cockroach genus name Blatta.

Type species: Helmablatta louisrothi Vidlička, Vršanský et Deharveng, sp. n. designated below by monotypy. 

Diagnosis. Differing from all living and fossil cockroach species in the presence of body modifications, mainly feature of tergal gland, tergal unpaired growth and excisions on both wing pairs. 
Cavernicolous. Spelaeoblatta-like. Male: Small, pale, eyes present but reduced. Tegmina abbreviated, lacking venation (only Sc allusively visible), apical half sinuous. Hind wings partly reduced, lacking venation, deep incision in apex. Abdomen short, abdominal tergal gland very well developed, composite of the three segments, T3-T5. Tergite 8 with large central anteriorly incurved hook. Legs long, coxae and femora robust, pulvilli and arolia absent, tarsal claws simple, symmetrical. Anteroventral margin of front femur with alternate large and small spines irregularly disposed and a large distal spine.


Helmablatta louisrothi Vidlička, Vršanský et Deharveng, sp. n.

Xyliphius sofiae 
Sabaj, Carvalho & Reis, 2017

 DOI:  10.1643/CI-16-456  

Xyliphius sofiae, new species, is described based on a unique specimen exhibiting four autapomorphies: eyes absent vs. present (though reduced); color pale, lacking pigment vs. head and body darkly pigmented; branchiostegal rays five vs. four; and unculiferous tubercles on posterior body distributed evenly vs. enlarged unculiferous tubercles typically arranged in five distinct rows above pelvic-fin base to posterior end of caudal peduncle. In addition, the pectoral fin of X. sofiae, new species, has one ossified proximal radial vs. two in congeners (except X. magdalenae, not examined). Xyliphius sofiae, new species, differs from all congeners except X. lepturus by snout tip elongated and narrowly rounded vs. short and broadly rounded, often with small median notch; fifth ceratobranchial relatively narrow with elongate acicular teeth vs. broadly expanded, leaf-shaped, with shorter and broader, conical teeth; anterior limits of branchial apertures separated by distance less than length of aperture vs. greater than length of aperture; anal-fin rays modally nine vs. seven; and lateral line extending onto base of caudal-fin rays vs. finishing in hypural region. Based on the single specimen collected in the main channel of the Río Amazonas near Iquitos, Peru, we describe the osteology of X. sofiae, new species, using a non-invasive technique: high-resolution X-ray computed tomography (HRXCT). We consider Xyliphius lombarderoi Risso and Risso, 1964, a species based on a unique holotype that is now lost, to be a subjective junior synonym of X. barbatus Alonso de Arámburu and Arámburu, 1962. Variable characteristics are summarized for the seven species of Xyliphius treated here as valid, and their distributions are plotted based on a comprehensive review of museum specimens.

Además, la aleta pectoral de X. sofiae tiene un radial proximal osificado vs dos en sus otros congéneres (no observado en X. magdalenae). Xyliphius sofiae se diferencia de todos sus congéneres, excepto X. lepturus, por la punta del hocico alargado y estrechamente redondeada vs. corto y ampliamente redondeado, a menudo con una pequeña muesca mediana; quinto ceratobranquial relativamente estrecho con los dientes aciculares alargados vs. ampliamente expandidos, en forma de hoja, con dientes cónicos y más amplios; límites anteriores de las aberturas branquiales separadas por la distancia menor que la longitud de la abertura vs. mayor que la longitud de la abertura; los radios de la aleta anal de forma modal nueve vs. siete y la linea lateral extendiendose posteriormente hasta la aleta caudal vs. linea lateral extendiendose posteriormente hasta los hipurales. El único espécimen de X. sofiae depositado en colecciones de museos fue colectado en el canal principal del Río Amazonas cerca de Iquitos, Peru y describimos su osteología utilizando técnicas no invasivas: tomografía computarizada en alta resolución. Xyliphius lombarderoi Risso and Risso, 1964, especie descrita solamente basado en el holotipo que está perdido, es considerado como sinónimo junior de X. barbatus Alonso de Arámburu y Arámburu, 1962.

Abstract

We describe the sixth species of bent-toed gecko from the Lesser Sunda Islands, Indonesia. This species was first collected on the banks of the Oi Marai River on the low northern slopes of Gunung (Mount) Tambora on Sumbawa Island. The new species is differentiated from Greater Sunda Islands (including Sulawesi) and Lesser Sunda Islands congeners by having the following unique combination of characters: (1) two scales between the second pair of postmentals in contact with the first pair; (2) dorsal surface of antebrachium tuberculate; (3) no tubercles on dorsal surface of brachium; (4) dorsal surfaces of thigh and crus tuberculate; (5) 18 irregularly aligned, longitudinal rows of keeled tubercles at midbody; (6) 26–27 paravertebral tubercles; (7) 40 ventral scales between indistinct ventrolateral folds; (8) 16–17 fourth-toe subdigital scales; (9) a continuous enlarged precloacal and femoral scales present, with the enlarged femoral scales arranged in three rows; (10) males with five to six precloacal pores, with four larger pores situated in a short groove; (11) femoral pores absent in both sexes; (12) lack of transversely enlarged subcaudal scales; and (13) 7–9 irregular, paired black blotches on the body.

Abstract
Quantifying the relationship between form and function can inform use of morphology as a surrogate for ecology. How the strength of this relationship varies continentally can inform understanding of evolutionary radiations; for example, does the relationship break down when certain lineages invade and diversify in novel habitats? The 75 species of Australian honeyeaters (Meliphagidae) are morphologically and ecologically diverse, with species feeding on nectar, insects, fruit, and other resources. We investigated Meliphagidae ecomorphology and community structure by (1) quantifying the concordance between morphology and ecology (foraging behavior), (2) estimating rates of trait evolution in relation to the packing of ecological space, and (3) comparing phylogenetic and trait community structure across the broad environmental gradients of the continent. We found that morphology explained 37% of the variance in ecology (and 62% vice versa), and we uncovered well-known bivariate relationships among the multivariate ecomorphological data. Ecological trait diversity declined less rapidly than phylogenetic diversity along a gradient of decreasing precipitation. We employ a new method (trait fields) and extend another (phylogenetic fields) to show that while species in phylogenetically clustered, arid-environment assemblages are similar morphologically, they are as varied in foraging behavior as those from more diverse assemblages. Thus, although closely related and similar morphologically, these arid-adapted species have diverged in ecological space to a similar degree as their mesic counterparts.

Abstract

Parsley frogs (Pelodytes) comprise the only genus in the family Pelodytidae, an ancient anuran lineage that split from their closest relatives over 140 million years ago. Pelodytes is a Palearctic group restricted to Western Eurasia including three extant species: the eastern species P. caucasicus, endemic to the Caucasus area, and two closely related species inhabiting Western Europe: the Iberian endemic P. ibericus and the more widespread P. punctatus. Previous studies based on mitochondrial and nuclear DNA markers have revealed the existence of two additional lineages of Parsley frogs in the Iberian Peninsula, which have been flagged as candidate species. Here, we integrate novel molecular, morphological and bioacoustical data to assess the differentiation of the four western Parsley frog lineages. Species trees and Bayesian population assignment analyses based on nuclear markers confirm previous studies and concordantly delineate four parapatric lineages with narrow hybrid zones. Mitochondrial divergence is low (< 2% pairwise distances in the 16S rRNA gene), in line with previously reported low mitochondrial substitution rates in non-neobatrachian frogs. Based on concordance between mitochondrial and nuclear markers, we conclude that four species of Parsley frogs occur in Western Europe: Pelodytes punctatus, distributed from northern Italy to northeastern Spain; Pelodytes ibericus, inhabiting southern Spain and southern Portugal; Pelodytes atlanticus sp. nov., from the Portuguese Atlantic coast; and Pelodytes hespericus sp. nov., occurring in central and eastern Spain. However, bioacoustical and morphological differentiation of these species is low, with no obvious and qualitative diagnostic characters allowing full species discrimination. Differences in the relative size of metacarpal tubercles exist but this character is variable. Pelodytes ibericus and Pelodytes atlanticus are smaller than the other two species, and Pibericus has shorter limbs and various distinctive osteological characters. Bioacoustically, the pattern by which two different note types are combined in advertisement calls separates P. hespericus from the remaining species. Despite these differences, we emphasize that the taxonomic status of all four western Parsley frogs requires additional investigation, especially the patterns of genetic admixture across contact zones. While a status of separate species best conforms to the currently available data, alternative hypotheses are also discussed.

Pelodytes atlanticus sp. nov.

Etymology. The specific epithet atlanticus is a genitive adjective derived from the name of Titan Atlas who, according to the ancient greek mythology, lived beyond the strait of Gibraltar and refers to the species’ exclusive distribution along the Atlantic coast of Portugal.

Pelodytes hespericus sp. nov. 

Etymology. The specific name is a latinized adjective derived from the name Hesperides (Ἑσπερίδες), Nymphs of the fading sun and daughters of the Titan Atlas, in allusion to an Iberian mythological garden. The Hesperian Massif also takes its name from the same etymology, meaning “western” in ancient greek, referring to its position in the Mediterranean sea.

[Botany • 2017] Endemic Palm Species (Allagoptera spp.) shed light on Habitat Shifts and the Assembly of the Cerrado and Restinga Floras

 Highlights
• Inter-specific relationships within Allagoptera are revealed.
• Recent origin of Cerrado and Restinga species.
• Specialization to dry habitats over time.
• Morphological adaptation to dry habitats found.

Abstract
Species expansions into new habitats are often associated with physiological adaptations, for instance when rain forest lineages colonize dry habitats. Although such shifts have been documented for the Brazilian savanna (Cerrado), little is known about the biogeographic origin of species occupying an extreme South American habitat type, the coastal dunes (Restinga). We examined the formation of this poorly known, endangered habitat by reconstructing the evolutionary history of two endemic species. Due to the proposed recency and uniqueness of this habitat, we hypothesized that Restinga species of the palm genus Allagoptera to be recently evolved and to present derived morphological characters. To detect habit shifts in absolute time, we used one plastid and nine nuclear genes to reconstruct the phylogenetic and biogeographic history of Allagoptera. We used light microscopy and stable isotope analysis to explore whether morphological adaptations occurred concomitantly with habitat shifts. Phylogenetic relationships were well supported and we found ancestral lineages of Allagoptera to be widely distributed throughout habitats that are currently occupied by extant species. Over the last ca. 7 Ma Allagoptera has shifted its preference to increasingly dry habitats. Coincident with the colonization of the Cerrado and Restinga, morphological adaptations also evolved, including subterranean stems that are fire-resistant and long underground stem and root systems that facilitate water access. We did not find differences in metabolic pathway or modifications to pollen morphology when compared to other palm lineages. Assuming that the evolutionary history of Allagoptera is indicative of the habitat in which it occurs, our results infer a recent origin for Cerrado species. Although little is known about the formation of the Restinga habitat, our results also suggest a longer history than currently proposed; with an origin of Restinga habitats dating back to the Late Pliocene.
