    Simothraulopsis diamantinensis Mariano, 2010


    Abstract

    In the present paper, based on specimens from different regions of Brazil, we review the current knowledge of the Neotropical genus Simothraulopsis. A phylogenetic study was performed in order to address the relationships between all species and to test the monophyly of Simothraulopsis. For this purpose, 48 characters related to the external morphology of adults and nymphs were investigated. As a result, four new species are described; Simothraulopsis caliginosus sp. nov., S. dominguezi sp. nov., S. eurybasis sp. nov., S. inaequalis sp. nov. New taxonomic and biological information are added to this genus. Nymphs of S. diamantinensis Mariano, 2010 and S. janaeMariano, 2010 are described for the first time and several new distributional records for Brazil are provided. Additionally, keys for male imagos and nymphs of the genus are proposed. The phylogenetic analysis corroborated the monophyly of Simothraulopsis, however, the division in two subgenera as previously proposed was not recovered in our reconstruction.

    Amphidraus zaque Galvis, 2017


    Abstract

    The Andean region of Northern South America is widely recognized as a hotspot with extreme levels of diversity, endemism, and threat. In a taxonomic study on jumping spiders from Colombia, nineteen new species of Amphidraus Simon, 1900 were found, all of which with small-scale endemic distributional patterns. Sixteen of these new species are described from the Andean region, eight of which being restricted to the Cundiboyacense high-Andean plateau (A. bochica sp. nov., A. guatavita sp. nov., A. mae sp. nov., A. pae sp. nov., A. sie sp. nov., A. sotairensis sp. nov., A. tisquesusa sp. nov. and A. tundama sp. nov.), in the Boyacá and Cundinamarca departments. The eight remaining Andean species are distributed out of this high-Andean plateau, in the Eastern Mountain Range of Boyacá (A. chie sp. nov., A. somondoco sp. nov. and A. sua sp. nov.), Cundinamarca (A. quinini sp. nov. and A. zaque sp. nov.), Huila (A. guaitipan sp. nov.) and Santander (A. zipa sp. nov.) departments, and in the Central Mountain Range of Risaralda department (A. quimbaya sp. nov.). Additionally, A. sikuani sp. nov. is described from the Eastern department of Meta, andA. colombianus sp. nov. andA. tanimuca sp. nov. from the Amazonian department of Vaupés. Finally, a map with these new records is included, along with a short comment about conservation of biota in the Andean region.

    Europatitan eastwoodi
    Fernández-Baldor​, Canudo​, Pedro Huerta​, Moreno-Azanza​ & Montero​, 2017

    .  DOI: 10.7717/peerj.3409 

    Abstract

    The sauropod of El Oterillo II is a specimen that was excavated from the Castrillo de la Reina Formation (Burgos, Spain), late Barremian–early Aptian, in the 2000s but initially remained undescribed. A tooth and elements of the axial skeleton, and the scapular and pelvic girdle, represent it. It is one of the most complete titanosauriform sauropods from the Early Cretaceous of Europe and presents an opportunity to deepen our understanding of the radiation of this clade in the Early Cretaceous and study the paleobiogeographical relationships of Iberia with Gondwana and with other parts of Laurasia. The late Barremian–early Aptian is the time interval in the Cretaceous with the greatest diversity of sauropod taxa described in Iberia: two titanosauriforms, Tastavinsaurus and Europatitan; and a rebbachisaurid, DemandasaurusThe new sauropod Europatitan eastwoodi n. gen. n. sp. presents a series of autapomorphic characters in the presacral vertebrae and scapula that distinguish it from the other sauropods of the Early Cretaceous of Iberia. Our phylogenetic study locates Europatitan as the basalmost member of the Somphospondyli, clearly differentiated from other clades such as Brachiosauridae and Titanosauria, and distantly related to the contemporaneous Tastavinsaurus. Europatitan could be a representative of a Eurogondwanan fauna like Demandasaurus, the other sauropod described from the Castrillo de la Reina Formation. The presence of a sauropod fauna with marked Gondwananan affinities in the Aptian of Iberia reinforces the idea of faunal exchanges between this continental masses during the Early Cretaceous. Further specimens and more detailed analysis are needed to elucidate if this Aptian fauna is caused by the presence of previously unnoticed Aptian land bridges, or it represents a relict fauna from an earlier dispersal event.

      Eutrema giganteum G.Q. Hao, Al-Shehbaz & J. Quan Liu 


    Abstract
    Eutrema giganteum (Brassicaceae), a new species from Hengduan Mountains in Sichuan Province, southwest China, is described, and its relationships to the closely related E. yunnanense is discussed based on morphological, cytological, and molecular data. It is similar morphologically to E. yunnanense but is readily distinguished by having robust (vs. slender), erect (vs. decumbent), and branched (vs. mostly simple), and rather tall stems (60–110 cm vs. 20–60 cm); curved (vs. straight), smooth (vs. torulose), and shorter fruit (5–8 mm vs. 8–15 mm); and fewer ovules per ovary (1–4 vs. 6–10). All examined individuals from different populations of E. giganteum clustered into a single clade sister to E. yunnanense in phylogenetic analyses using the combined nuclear ITS and plastid DNA datasets. Our cytological studies revealed that the chromosome number of E. giganteum is 2n = 44, with a genome size of 1160 (±8) Mb, while that of E. yunnanense is 2n = 28, with a genome size of 718 (±15) Mb. Multiple lines of evidence support the recognition of E. giganteum as a distinct species well differentiated from E. yunnanense.

    Coronodon havensteini  
    Geisler, Boessenecker, Brown & Beatty, 2017


    Illustration: A. Gennari DOI: 10.1016/j.cub.2017.06.003 

     Highlights
    • A new species of 30 million year old whale has been found near Charleston, South Carolina
    • This new species is a relative of modern baleen-bearing whales but retains teeth
    • Its molars are large, multi-cusped, and overlapping and were used for filter feeding
    • Filter feeding evolved before baleen; early whales had teeth and baleen

    Summary
    As the largest known vertebrates of all time, mysticetes depend on keratinous sieves called baleen to capture enough small prey to sustain their enormous size. The origins of baleen are controversial: one hypothesis suggests that teeth were lost during a suction-feeding stage of mysticete evolution and that baleen evolved thereafter, whereas another suggests that baleen evolved before teeth were lost. Here we report a new species of toothed mysticete, Coronodon havensteini, from the Oligocene of South Carolina that is transitional between raptorial archaeocete whales and modern mysticetes. Although the morphology and wear on its anterior teeth indicate that it captured large prey, its broad, imbricated, multi-cusped lower molars frame narrow slots that were likely used for filter feeding. Coronodon havensteini is a basal, if not the most basal, mysticete, and our analysis suggests that it is representative of an initial stage of mysticete evolution in which teeth were functional analogs to baleen. In later lineages, the diastema between teeth increased—in some cases, markedly so—and may mark a stage at which the balance of the oral fissure shifted from mostly teeth to mostly baleen. When placed in a phylogenetic context, our new taxon indicates that filter feeding was preceded by raptorial feeding and that suction feeding evolved separately within a clade removed from modern baleen whales.

    Coronodon havensteini gen. et sp. nov.

    Holotype: CCNHM 108. Nearly complete, 1.0-m-long skull, mandibles, 14 vertebrae, and partial ribs (Figures 1, 2, and 3; Figures S1–S3; Tables S1 and S2).

    Etymology: Coronodon havensteini. Genus is Greek for “crown tooth,” referring to the multi-cusped molars. The species name recognizes Mark Havenstein, who discovered the holotype.

    Locality and Age: Wando River near Highway 41 Bridge, South Carolina, Berkeley County. Ashley Formation, Oligocene, uppermost Rupelian. 

    Diagnosis: Coronodon has the following mysticete synapomorphies: supraoccipital level with temporal fossa (character 25: state 1), broad basioccipital crests (39: 2), all cusps of posterior teeth subequal (99: 1), upturned antorbital process of maxilla (100: 1), and splayed basal cusps on posterior teeth (206: 1). Like some archaeocetes, its rostrum is twisted counterclockwise in anterior view (Figure 3). Coronodon havensteini is unique in having anterior lower molars labially overlapping posterior lower molars.  ....




    In this reconstruction, the two main whales in the center are Coronodon havensteini, the lower two in the background are Echovenator sandersi), and the birds in the sky are Pelagornis sandersi (false toothed birds with a wingspan near 6.5 m).

    Zorotypus asymmetricus Kocarek, 2017


    Abstract
    A new species of Zoraptera from Borneo is described and figured. Zorotypus asymmetricus sp. nov. was discovered in lowland mixed dipterocarp forest in Ulu Temburong, Brunei Darussalam. The species represents the third known species occurring on Borneo and it can be easily distinguished from others by the asymmetrical cerci: the right cercus is strongly enlarged and curved.

    Keywords: Zoraptypus, Zoraptera, Zorotypidae, new species, Borneo, Indomalayan region

    Zorotypus asymmetricus sp. nov. 
    1, male habitus of living specimen; 17, living apterous male; 18, rotting logs in Sungai Esu stream valley where Z.asymmetricus sp. nov. was collected.

    Diagnosis. The new species is similar to Zorotypus sinensisHwang, 1974, Z. medoensis Hwang 1976, Z. impolitusMashimo, Engel, Dallai, Beutel & Machida 2013 and Z. weiwei (Hwang 1974, 1976; Mashimo 2013; Wang et al. 2016), but it can be easily distinguished from them by the asymmetrical cerci, with the right cercus noticeably enlarged and sickle-shaped (Figs. 9–11), the species-specific shape of the male genitalia (Fig. 13), and the presence of 7‒8 stout, long spines on the ventral surface of metafemur. The body is typically matte dark brown with the exception of pale yellowish gray tibiae and tarsi on all legs and antennomeres VI‒IX.

    Etymology. The name refers to the asymmetrical cerci and asymmetrical abdominal sternite S9 in males.

     Distribution and occupied habitat. Zorotypus asymmetricus sp. nov. was collected under the bark of rotting logs in shade in the valley of Sungai Esu stream (Fig. 18). The species is currently known only from Ulu Temburong National Park in Brunei Darussalam, but we expect its occurrence in similar habitats throughout Borneo.

    Vietnamocasia dauae N.S. Lý, T. Haevermans, Y.S. Wong & D.V. Nguyen

    Abstract

    Vietnamocasia, a new monotypic aroid genus in the Alocasia-Colocasia clade, is described with the type species, Vietnamocasia dauaeVietnamocasia is distinguished by possessing free individual staminate flowers, lacking expanded synconnectives, and having nodding inflorescences. Vegetatively Vietnamocasia is reminiscent of species of the distantly closely related Alocasia Cuprea Group, although Vietnamocasia is so far only known from the type locality in Central Vietnam, over 1200 km NE from the nearest representative of the Alocasia Cuprea Group. The phylogenetic analyses of Vietnamocasia dauae together with representative taxa from all genera of the Alocasia-Colocasia clade recovered Vietnamocasia as a strongly supported clade sister to Alocasia, together nested in a clade to which Leucocasia is a sister taxon. Vietnamocasia dauae is illustrated from living plants and with a line drawing. A key to all genera of Alocasia-Colocasia clade is included.

     Etymology:— Vietnamocasia is compounded from the Greek classical name kolokasia, itself from an old Middle Eastern name qolqas (Nicolson 1987) and the root of Alocasia and Leucocasia (and the more distantly related Colocasia) + Vietnam. 

    Distribution:— Vietnamocasia is so far known only from the type locality and its vicinity. 

    Ecology:— At Mount Dầu Vietnamocasia dauae grows in moist shady understory of hillsides in secondary broadleaved forest dominated by dipterocarps at 150–490 m elevation. At the other known locality, Cà Đam, it occurs in primary evergreen broad-leaf forest at about 790 m elevation.

    Vietnamocasia dauae N. S. Lý, T. Haevermans, Y. S. Wong & D. V. Nguyen, sp. nov.

    Abstract

    A new species of Campylopterus sabrewing is described from eastern Brazilian tropical dry forests occurring below 900 m asl. Its holotype (MZUSP 99024) is an adult female from Sítio Duboca (16°43’19’’S, 43°58’20’’W, elevation 840 m), municipality of Montes Claros, state of Minas Gerais. A taxonomic revision based on more than 1,000 museum specimens revealed that the new taxon, together with C. largipennis, C. diamantinensis and C. obscurus(with C. aequatorialis considered as a subjective junior synonym) should be ranked as species. We provide a key to permit easy identification of the four species. The new species is very similar to the parapatric C. diamantinensis of high altitude “campos rupestres” above 1,000 m asl, differing from it by its smaller size and longer light tail tips, as well as by sternum measurements. Given the several threats faced by the habitat to which the new species is endemic, we propose to consider it as Vulnerable under the IUCN criteria.

      A young male of Campylopterus calcirupicola captured on 18 July 2006 in the Fazenda Corredor (880 m asl), municipality of Bocaiúva, Minas Gerais, Brazil (DZUFMG 5005). Photographs by LEL. 

    Campylopterus calcirupicola sp. nov. Dry-forest Sabrewing (English)
    Asa-de-sabre-da-mata-seca (Portuguese)

    Etymology. The name calcirupicola is Latin, composed by “calx”, calcis, limestone; “rupes”, steep rocks; and “cola”, dwelling (Eggli & Newton 2004). It refers to the habitat of this new hummingbird, which inhabits dry forests growing on limestone outcrops. This specific name matches that for the cactus Cereus calcirupicola F. Ritter, found in the type locality and in the same habitat (Ritter 1979) of the new hummingbird. The vernacular names we propose also refer to the habitat used by the new species.

    Geographic distribution. Campylopterus calcirupicola has been recorded from Divinópolis de Goiás (northeastern state of Goiás) and Coribe (southwestern state of Bahia) to Bocaiúva (northern state of Minas Gerais) on both banks of the São Francisco River, as well as in the Paranã River valley, an important tributary of the Tocantins River, west of the Serra Geral (Figures 9 and 10). The altitudinal range of this new species is between 460–880 m asl. The range of C. calcirupicola probably extends to southeastern Tocantins (Dornas et al. 2014) and the southern part of the state of Piauí (Santos 2004), from where there are sight records of C. largipennis. We believe that the specimen of C. largipennis from “Posse, Goiás” cited by Silva (1990) as housed in the MNRJ refers to the specimen from “Galheiros” housed in the same institution and mentioned by Ruschi (1951), probably representing a toponymic mistake committed by Silva (1990).

    Eusaurosphargis dalsassoi Nosotti & Rieppel, 2003

    Abstract
    Recently it was suggested that the phylogenetic clustering of Mesozoic marine reptile lineages, such as thalattosaurs, the very successful fish-shaped ichthyosaurs and sauropterygians (including plesiosaurs), among others, in a so-called ‘superclade’ is an artefact linked to convergent evolution of morphological characters associated with a shared marine lifestyle. Accordingly, partial ‘un-scoring’ of the problematic phylogenetic characters was proposed. Here we report a new, exceptionally preserved and mostly articulated juvenile skeleton of the diapsid reptile, Eusaurosphargis dalsassoi, a species previously recovered within the marine reptile ‘superclade’, for which we now provide a revised diagnosis. Using micro-computed tomography, we show that besides having a deep skull with a short and broad rostrum, the most outstanding feature of the new specimen is extensive, complex body armour, mostly preserved in situ, along its vertebrae, ribs, and forelimbs, as well as a row of flat, keeled ventrolateral osteoderms associated with the gastralia. As a whole, the anatomical features support an essentially terrestrial lifestyle of the animal. A review of the proposed partial character ‘un-scoring’ using three published data matrices indicate that this approach is flawed and should be avoided, and that within the marine reptile ‘superclade’ E. dalsassoi potentially is the sister taxon of Sauropterygia.

    Abstract
    We describe remains of a new crocodyliform found from the Lower Cretaceous (Aptian) Khok Kruat Formation, northeastern Thailand. Remains consist of two caudal ends of mandibles, two rostral symphyseal parts of right rami of mandibles, a dorsal part of postorbital, a cranial end of squamosal and one osteoderm. Phylogenetic analyses supported inclusion of this crocodyliform into the Eusuchia as it shares several morphological characters with other eusuchians, such as a dorsocaudally oriented retroarticular process, smooth lateral surface of the caudoventral region of mandible, and a craniocaudally oriented ridge on the dorsal surface of retroarticular process. The shape of symphyseal region showed this crocodyliform had a longirostrine snout shape, which is uncommon in early eusuchians. Finding of this crocodyliform draws back the oldest record of Asian eusuchians, which was Tadzhikosuchus, approximately 30 million years and it is the only Mesozoic eusuchian found in East and Southeast Asia.

    Conclusions: 
     Morphological comparison and phylogenetic analysis showed the Ban Saphan Hin crocodyliform is a member of Eusuchia. But due to its fragmentary nature its phylogenetic position within Eusuchia is currently uncertain. The Ban Saphan Hin crocodyliform indicates longirostrine snout shape evolved during the early stage of eusuchian, which is probably independent from that of gavialoids. Moreover it draws back the oldest record of Asian eusuchians from the Santonian, Tadzhikosuchus found from Tadzhikistan, to the Aptian, approximately 30 million years ( Storrs and Efimov, 2000), and it is the only Mesozoic eusuchian found in East and Southeast Asia. This situation reflects the patchy fossil record of Mesozoic crocodyliform in these areas. The Late Cretaceous crocodyliforms of East Asia were reported only from Mongolia (Storrs and Efimov, 2000; Turner, 2015). Further sampling effort is required to reveal the complex evolutionary history of Asian Mesozoic neosuchians.

     Chu, Zhou & Sun, 2017


    Abstract

    A new genus Arquatopotamon gen. n. of the family Potamidae Ortmann, 1896, is established and a new species, Arquatopotamon jizushanense sp. n. from Yunnan Province, China is described. The new genus is established based on the distinctive distal part of the male first gonopod, with arched-shaped subterminal and terminal segments (in mesioventral view) and female gonopores (vulvae) on thoracic sternites 5/6 and a combination of characters including the carapace and male telson, while it is similar to the five known genera in Yunnan Province and adjacent area, Tenuipotamon Dai, 1990Pararanguna Dai & Chen, 1985Trichopotamon Dai & Chen, 1985Potamiscus Alcock, 1909 and Aparapotamon Dai & Chen, 1985, in having a third maxilliped exopod without a flagellum. Present molecular data based on a barcoding marker of 16S rDNA provide strong support for the genus as being new.

     Rhynchocypris deogyuensis
    Lee& Sim, 2017 



    A new species of deogyu fat-minnow, Rhynchocypris deogyuensis, is described from the Geum River in Korea. This species is distinguished from Rhynchocypris kumgangensis by the following characteristics: shorter interorbital width; shorter eye diameter; longer caudal peduncle depth; number of scales above lateral line; and black transverse bar on the first unbranched ray in dorsal fin. The lower band of yellowish longitudinal two bands on lateral body is interrupted and unsharpened. Numerous silverly white spots are on blackish dorso-lateral body. Analyses of 1,141 bp length of mitochondrial Cyt b gene proved that, R. deogyuensis is clearly distinguished from R. kumgangensis in that the former showed a high level (94 bootstrap) of reliability.

    Key words: New species, Rhynchocypris deogyuensis, Fat-minnow, Cyprinidae, Geum River

    plumage patterns of some taxa of the Pyrrhura picta-leucotis complex.



    Abstract
    Introduction: The relationships within the Pyrrhura species complex are partly unresolved. In this study, a comprehensive phylogenetic analysis of the Pyrrhura picta-leucotis complex was carried out, covering all species except P. subandina.

    Material and Methods: We made a morphological analysis of 745 preserved specimens of all the taxa in different museums. Nucleotide sequences of the mitochondrial cytochrome gene were generated and used to reconstruct a molecular phylogeny of Pyrrhura.

     Results and Discussion: Our results show that the complex is divided into 6 main groups comprising 15 species. P. dilutissima, regarded up to now as a subspecies of Pperuviana, acquires species status and three new subspecies are described. We also provide evidence that P. roseifrons is a paraphyletic group, indicating the existence of probably 3 lineages of which 2 deserve species status.

    Eekaulostomus cuevasae 
    Cantalice & Alvarado-Ortega,  2016

    ABSTRACT
    Eekaulostomus cuevasae gen. and sp. nov. is described and identified here as a new member of the superfamily Aulostomoidea. The single specimen known of this species is part of a newly fossil assemblage collected in the marine sediments belonging to the early Paleocene Tenejapa-Lacandón geological unit, exploited in the Belisario Domínguez quarry, near Palenque town, State of Chiapas, southeastern Mexico. E. cuevasae represents the oldest aulostomoid as far known and the first fossil species of this superfamily collected in America. E. cuevasae differs from other aulostomoids in the presence of two spines preceding the soft rays of both dorsal and anal fins; the star-like scales covering the entire body and part of the snout; as well as the relative large number of principal rays in the caudal fin. The recognition of E. cuevasae as the stem group of Aulostomoidea increases the temporal and geographic distribution of this superfamily up to Danian and within the Caribbean region, when a large part of Chiapas was under the sea after the Cretaceous-Tertiary mass extinction event. This finding also provides evidences suggesting the membership of Aulostomoidea within the order Gasterosteiformes, in which the scutes covering the trunk and the robust spines in unpaired fins are recurrent features.

    Derivation of name. The genus name includes the Mayan word “Eek” (= star), the Greek word "aulos" (= αὐλός, that is the name of an ancient flute), and the Latin word "stoma" (= mouth). The name refers to a "fish with a star-like scutes and flute-shaped mouth."
    Eekaulostomus cuevasae sp. nov.
    Derivation of name. The specific epithet of this fish honors our colleague, Martha Cuevas García, whose dedication and newly passion for the fossils led us to find the only specimen of Eekaulostomus cuevasae.

    Occurrence. Paleocene (Danian, ≈ 63Ma) marine strata of the Tenejapa-Lacandón geological unit. Belisario Domínguez quarry, Salto de Agua Municipality, State of Chiapas, southeastern Mexico (Alvarado-Ortega et al., 2015).

    Diagnosis. Aulostomoidea fish with rigid star-like scutes covering the whole trunk and part of the snout; pelvic fin placed anteriorly, just behind the postcleithrum; two spines in front of the soft rays of dorsal and anal fins; eight soft rays in both anal and dorsal fins; caudal fin formula iv+I+7—5+I+iii.
    CONCLUSIONS 
    Fossils referring to the superfamily Aulostomoidea had been collected more than 200 years ago in Eocene and younger marine deposits along Europe. Although the extant aulostomoids form part of large modern cladistics essays, some are based on morphological evidences and others on molecular data; unfortunately, the fossil aulostomoids have never been phylogenetically studied. This situation has prevented the generation of a robust classification of the aulostomoids, and at the same time, has fueled the differences and contradictions between the phylogenetic hypotheses already published. It is so, that it is desirable to make these European fossils part of future cladistic studies; however, first we have to fulfill the task of re-describing them accurately using modern and homogeneous criteria. Only up to the present day, the distribution of fossil aulostomoids was restricted to Europe. Although this fact has not interested paleontologists outside of Europe to further collaborate in studies concerning the diversity evolution of aulostomoids; the goal of this paper is to provide the first tangible evidence that in the past, this fish group was also an inhabitant of the American seas.

    From now on, we must take more seriously the paleontological surveys on late Cretaceous and early Paleocene sites with marine sediments present throughout the tropical region of America. As present study shows, fossils may exist that allow us to delve into the details of the evolution of the fishes on both sides of Cretaceous-Tertiary mass extinction event. Sadly, during the joint INAH-UNAM project, from which this article was drawn, no other fossil aulostomoid was recovered; however, the collection effort applied in Belisario Domínguez (where Eekaulostomus cuevasae gen. and sp. nov. came) as well as in its coeval and neighbor quarry, División del Norte, both with Danian marine sediments, really is far from reaching saturation.

    The re-examination of the relationships of the Aulostomoidea executed here, using datasets previously generated by other authors and including Eekaulostomus cuevasae gen. and sp. nov., might not be the best way to achieve the desired understanding on the evolutionary processes of these fishes; however, this exercise significantly contributes to this goal. On the one side, the undeniable position of this new species as a primitive aulostomoid member, together with its deep morphological differences with other extinct and living taxa formally, or putatively, included in such superfamily, trace possible trends in morphological changes experienced by these fishes since the Paleocene to the present. This essay also widens the geographical scenario where the evolution of these fishes took place, extending from Europe to the tropical region of America.
