[Arachnida • 2018] The Cave-dwelling False Scorpion Genus Pseudoblothrus Beier, 1931 (Pseudoscorpiones: Syarinidae) in the Crimean Peninsula


Pseudoblothrus roszkovskii  (Redikorzev, 1918)

in Kolesnikov & Turbanov, 2018.

Abstract 

Based on morphological and molecular studies of material from caves in three karst regions of Crimea, the small, apparently relictual, Euro-Mediterranean and Macaronesian false scorpion genus Pseudoblothrus Beier, 1931 is shown to contain only one troglobiont species there, P. roszkovskii (Redikorzev, 1918), of which P. ljovuschkini Krumpál, 1984 and Obisium tauricum Lebedev, 1927 are junior subjective synonyms. A detailed redescription of the adults and tritonymph of P. roszkovskii is provided, together with phylogenetic and zoogeographical analyses.

[PaleoMammalogy • 2017] Gomphotherium tassyi • A New Species of Gomphotherium (Proboscidea, Mammalia) from China and the Evolution of Gomphotherium in Eurasia


Gomphotherium tassyi
 Wang, Li, Duangkrayom, Yang, He & Chen, 2017


ABSTRACT
Gomphotherium is a stem taxon of Elephantida that was widespread in Africa, Eurasia, and North America during the Miocene. However, the evolution of this genus is greatly debated because of morphological variation among the species of Gomphotherium. In the present work, we describe a cranium and accompanying material of Gomphotherium from the late middle Miocene Hujialiang Formation of Linxia Basin, China. The new material shows dental similarities to G. subtapiroideum from the middle Miocene of Europe; however, it displays some cranial, mandibular, and dental feature combinations that are distinct from the known species of Gomphotherium. Therefore, a new speciesGomphotherium tassyi, is established. We further study the phylogeny of Gomphotherium by cladistic analysis and recognize four groups. The most basal ‘G. annectens group’ is a paraphyletic group that includes G. annectens, G. cooperi, G. sylvaticum, and G. hannibali. The African taxa, G. libycum and G. pygmaeus, constitute a monophyletic group that has not been named. The ‘G. angustidens group’ is a monophyletic group that includes G. inopinatum, G. mongoliense, G. connexum, and G. angustidens. In addition, the ‘derived Gomphotherium group,’ which includes G. subtapiroideum, G. tassyi, G. wimani, G. browni, G. productum, and G. steinheimense, was widely distributed in Eurasia and North America during the middle and late Miocene.

[Paleontology • 2018] A Revised Cranial Description of Massospondylus carinatus Owen (Dinosauria: Sauropodomorpha) based on Computed Tomographic Scans and A Review of Cranial Characters for Basal Sauropodomorpha


Massospondylus carinatus  Owen, 1854

in Chapelle & Choiniere, 2018
   DOI: 10.7717/peerj.4224 

Abstract

Massospondylus carinatus is a basal sauropodomorph dinosaur from the early Jurassic Elliot Formation of South Africa. It is one of the best-represented fossil dinosaur taxa, known from hundreds of specimens including at least 13 complete or nearly complete skulls. Surprisingly, the internal cranial anatomy of M. carinatus has never been described using computed tomography (CT) methods. Using CT scans and 3D digital representations, we digitally reconstruct the bones of the facial skeleton, braincase, and palate of a complete, undistorted cranium of M. carinatus (BP/1/5241). We describe the anatomical features of the cranial bones, and compare them to other closely related sauropodomorph taxa such as Plateosaurus erlenbergiensis, Lufengosaurus huenei, Sarahsaurus aurifontanalis and Efraasia minor. We identify a suite of character states of the skull and braincase for M. carinatus that sets it apart from other taxa, but these remain tentative due to the lack of comparative sauropodomorph braincase descriptions in the literature. Furthermore, we hypothesize 27 new cranial characters useful for determining relationships in non-sauropodan Sauropodomorpha, delete five pre-existing characters and revise the scores of several existing cranial characters to make more explicit homology statements. All the characters that we hypothesized or revised are illustrated. Using parsimony as an optimality criterion, we then test the relationships of M. carinatus (using BP/1/5241 as a specimen-level exemplar) in our revised phylogenetic data matrix.

Conclusion: 
The use of CT scanning and 3D visualization graphics allows for a better understanding of the internal and external morphological structures of the braincase as well as information about the soft tissues such as the vestibular canals. M. carinatus can be tentatively diagnosed cranially by basipterygoid processes that are separated by an angle smaller than 60° and a jugal process of the ectopterygoid that is strongly curved. A revision of cranial characters provides a basis for more comparative work on the braincase of sauropodomorphs in general. Results also show a well-supported Massospondylidae clade. Further phylogenetic analyses using individual specimens of known ontogenetic stages as operational taxonomic units would provide better resolution for the Massospondylidae clade as well as a better understanding of which sets of character states set M. carinatus aside from other taxa.

[Crustacea • 2018] Caligoneus cavernicola • A New Genus and New Species of Alpheid Shrimp (Decapoda: Caridea) from A Marine Cave in the Ryukyu Islands, Japan, with Additional Record of Salmoneus antricola


Caligoneus cavernicola
 Komai & Fujita, 2018


Abstract

Two species of alpheid shrimp collected from a marine cave off Ie Island, Okinawa Islands, Ryukyu Islands, Japan, are reported. Caligoneus cavernicola n. gen., n. sp., is described on the basis of six specimens, including two ovigerous individuals. The new monotypic genus shares a number of features with Salmoneus Holthuis, 1955 and Triacanthoneus Anker, 2010; however, the dorsally elevated rostrum and the symmetrical pereopods 1 (= chelipeds) of “minor form” distinguish Caligoneus n. gen. from the latter two genera. Other potentially diagnostic characters between the new genus and the latter two genera are also discussed. The new taxon is clearly adapted to stygobiotic environments, with its reduced cornea and very slender elongate pereopods. In addition, two complete specimens of Salmoneus antricola Komai, Yamada & Yunokawa, 2015, collected in the same cave, supplement the original description of the species, which was based on a unique holotype with a damaged telson.

[Botany • 2018] Rediscovery of the Presumed-Extinct Dracaena umbraculifera || A Botanical Mystery Solved by Phylogenetic Analysis of Botanical Garden Collections

Abstract
Extinction is the complete loss of a species, but the accuracy of that status depends on the overall information about the species. Dracaena umbraculifera was described in 1797 from a cultivated plant attributed to Mauritius, but repeated surveys failed to relocate it and it was categorized as Extinct on the IUCN Red List. However, several individuals labelled as D. umbraculifera grow in botanical gardens, suggesting that the species’ IUCN status may be inaccurate. The goal of this study was to understand (1) where D. umbraculifera originated, (2) which species are its close relatives, (3) whether it is extinct, and (4) the identity of the botanical garden accessions and whether they have conservation value. We sequenced a cpDNA region of Dracaena from Mauritius, botanical garden accessions labelled as D. umbraculifera, and individuals confirmed to be D. umbraculifera based on morphology, one of which is a living plant in a private garden. We included GenBank accessions of Dracaena from Madagascar and other locations and reconstructed the phylogeny using Bayesian and parsimony approaches. Phylogenies indicated that D. umbraculifera is more closely related to Dracaena reflexa from Madagascar than to Mauritian Dracaena. As anecdotal information indicated that the living D. umbraculifera originated from Madagascar, we conducted field expeditions there and located five wild populations; the species’ IUCN status should therefore be Critically Endangered because < 50 wild individuals remain. Although the identity of many botanical garden samples remains unresolved, this study highlights the importance of living collections for facilitating new discoveries and the importance of documenting and conserving the flora of Madagascar.

[Herpetology • 2018] Systematics and Phylogeography of the Widely Distributed African Skink Trachylepis varia Species Complex: Trachylepis varia, T. damarana & T. laevigata



 Weinell & Bauer, 2018.

Highlights
• A molecular systematic study was conducted for the wide-ranging Trachylepis varia complex.
• Phylogenetic analyses support the existence of at least eight species within the Trachylepis varia complex.
• The Southern African members of the Trachylepis varia complex are phenotypically distinct.
• We update the taxonomy for the southern Africa members of the Trachylepis varia complex.
• Diversification within the Trachylepis varia complex began during the mid to late Miocene or early Pliocene.


Abstract
A systematic study of the Trachylepis varia complex was conducted using mitochondrial and nuclear DNA markers for individuals sampled across the species range. The taxonomic history of T. varia has been complicated and its broad geographic distribution and considerable phenotypic variation has made taxonomic revision difficult, leading earlier taxonomists to suggest that T. varia is a species complex. We used maximum likelihood and Bayesian inference to estimate gene trees and a multilocus time-tree, respectively, and we used these trees to identify the major clades (putative species) within T. varia. Additionally, we used morphological and color pattern data to distinguish and revise the taxonomy of the southern African clades. The major clades recovered in the multilocus time-tree were recovered in each of gene trees, although the relationships among these major clades differed across gene trees. Genetic data support the existence of at least eight species within the T. varia complex, each of which originated during the mid to late Miocene or early Pliocene. We focus our systematic discussion on the southern African members of the T. varia complex, revive Trachylepis damarana (Peters, 1870) and T. laevigata (Peters, 1869), and designate lectotypes for T. damarana and T. varia.

Trachylepis damarana (Peters, 1870)
Euprepes damaranus Peters, 1870

  Trachylepis damarana from Haenertsberg, Limpopo Province, South Africa.


Conclusions: 
We find strong evidence that Trachylepis varia, T. damarana, and T. laevigata are distinct species that occur in southern Africa and that five additional, species-level clades occur north of the Zambezi and Kunene rivers, although future studies are needed to determine whether Trachylepis nyikae and Trachylepis isellii should also be recognized. The allopatric distribution and morphological distinctiveness of T. isellii (Largen and Spawls, 2010) suggests that this species is probably valid and the presence of multiple endemic species on the Nyika Plateau (Poynton, 1997; Burrows and Willis, 2005) suggests that T. nyikae may also be a valid species. Additionally, little is known about the distribution or natural history of the undescribed species sampled in Ethiopia, Democratic Republic of the Congo, or Tanzania. Lastly, next generation DNA sequencing may be useful in resolving deeper phylogenetic relationships within the T. varia complex and for distinguishing historical gene flow from incomplete lineage sorting. This study is the first to use genetic data to address species diversity, phylogenetic history, and taxonomic issues for the T. varia complex and is an example of how both genetic and phenotypic data can be used to resolve taxonomic problems and to estimate species ranges.

[Botany • 2018] Thismia thaithongiana • A New Species of Mycoheterotroph (Dioscoreaceae: Thismieae) from An Unusual Habitat in Thailand


Thismia thaithongiana
 Chantanaorr. & Suddee

in Chantanaorrapint & Suddee, 2018.

With more than 60 currently accepted species, Thismia Griffith (1844: 221) is the largest genus of the tribe Thismieae of Dioscoreaceae (sensu APG 2016, or Thismiaceae of other authors). The genus is widely distributed mainly in the tropical and subtropical regions with a concentration of species in Southeast Asia (ca. 30 species) including the Malay Peninsula, Sumatra, Java, Borneo, Thailand and Vietnam. In last decade, many new taxa have been described from Southeast Asia (e.g. Larsen & Averyanov 2007, Chantanaorrapint 2008 2012, Tsukaya & Okada 2012, Dančák et al. 2013, Nuraliev et al. 2014 2015, Truong et al. 2014, Tsukaya et al. 2014, Chantanaorrapint & Sridith 2015, Hroneš et al. 2015, Chantanaorrapint et al. 2016, Sochor et al. 2017). Members of the genus are small mycoheterotrophic herbs with a highly reduced habit and usually grow among leaf litter in shady wet forests.

 Abstract
A 2015 trawl survey along the coast of Myanmar provided an opportunity to assess species of the triglid genus Lepidotrigla occurring in the country. Three species, L. longipinnis Alcock, 1890, L. omanensis Regan, 1905, and an undescribed species, were identified among the 15 voucher specimens retained. A formal description of the unnamed species, as well as descriptive accounts of the other two are provided. Lepidotrigla psolokerkos, new species, based on two specimens, resembles L. alcocki Regan, 1908 described from the Saya de Malho Bank in the central Indian Ocean, differing from it in having fewer oblique scale rows between the anal fin origin and the lateral line and broader covering of dark pigmentation on the inner surface of the pectoral fin. The known geographical ranges of L. longipinnis, reported in the literature as L. riggsi Richards & Saksena, 1977, and L. omanensis are extended to the Andaman Sea off south-eastern Myanmar. A key is provided for the three species occurring in the survey area.

SYSTEMATICS 

Lepidotrigla longipinnis Alcock, 1890 
Proposed vernacular: Stellar Gurnard

Etymology. Initially proposed as a varietal name, longipinnis is an amalgamation of the Latin “longus” for long and “pinna” for fin, in reference to the longer pectoral fin that was considered by Alcock (1890) to distinguish what is now recognised as a distinct species from L. spiloptera Günther, 1860. 

Distribution. Confined to coastal waters of the northern Indian Ocean, from at least Bombay, India to just south of the equator off the west coast of Sumatra, Indonesia (Fig. 4) at depths of 70 to at least 107 m.


Lepidotrigla omanensis Regan, 1905 
Vernacular: Oman Gurnard 

Etymology. Regan’s (1905) omanensis was named for the collecting locality “the Sea of Oman” for his three type specimens. 
Distribution. Occurs in coastal waters of the northern Indian Ocean from the Gulf of Aden to the Andaman Sea off south-eastern Myanmar (Fig. 4) at depths of 41–335 m; apparently excluded from the Persian Gulf.


Lepidotrigla psolokerkos new species 
Proposed vernacular: Skinny Gurnard

Etymology. The name psolokerkos is a conjunction of the Greek psolos for “dirt” and “kerkos” for tail in reference to the distinctive grey blotch dorsoposteriorly on the caudal fin of this species. 

Distribution. Known only from the two type specimens collected in the Andaman Sea off south-eastern Myanmar (Fig. 4) at depths of 151–255 m.

[Ornithology • 2018] Structural Absorption by Barbule Microstructures of Super Black Bird of Paradise Feathers

Abstract
Many studies have shown how pigments and internal nanostructures generate color in nature. External surface structures can also influence appearance, such as by causing multiple scattering of light (structural absorption) to produce a velvety, super black appearance. Here we show that feathers from five species of birds of paradise (Aves: Paradisaeidae) structurally absorb incident light to produce extremely low-reflectance, super black plumages. Directional reflectance of these feathers (0.05–0.31%) approaches that of man-made ultra-absorbent materials. SEM, nano-CT, and ray-tracing simulations show that super black feathers have titled arrays of highly modified barbules, which cause more multiple scattering, resulting in more structural absorption, than normal black feathers. Super black feathers have an extreme directional reflectance bias and appear darkest when viewed from the distal direction. We hypothesize that structurally absorbing, super black plumage evolved through sensory bias to enhance the perceived brilliance of adjacent color patches during courtship display.

Sungur, Jalili & Eagderi, 2017


Abstract
 A new species of nemacheilid fish, Oxynoemacheilus ciceki sp. n. is described from the Sultan Marsh, Kayseri Province, Turkey. The species differs from its congeners in the combination of the following characters: flank yellowish brown or pale gray with irregular spot; cheeks with numerous tiny spots; lacking scale; thinner caudal peduncle; complete lateral line; 4 central and 4 lateral pores in the supra-temporal canal; lower lip thick with a deep median interruption and marked furrows and small median incision in upper lip.

 Keywords: Freshwater fish, Taxonomy, Morphology, Loach.

Oxynoemacheilus ciceki sp. n. 

Diagnosis: Oxynoemacheilus ciceki sp. n. is distinguished from the other species of Oxynoemacheilus in the Kızılırmak basin by a combination of characters, none of them unique. Oxynoemacheilus ciceki sp. n. is distinguished from O. angorae by having flank yellowish brown or pale gray with irregular spots (vs. yellowish with a mid-lateral row of horizontally elongated fused blotches), cheeks with numerous tiny spots (vs. without pigmentation), without scale (vs. scaled), shorter pelvic fin (11.3- 13.6 vs. 14.9-17.0 %SL), lower mouth width (16.0- 22.0 vs. 20.6-26.7 %HL).

Etymology: The new species is named after Prof. Dr. Erdoğan Çiçek, for his valuable contribution to the knowledge of freshwater fishes of Turkey.

Distribution: Oxynoemacheilus ciceki sp. n. is knowns only from the Sultan Marsh, Kayseri Province (Fig. 6). This species mostly found slowflowing parts of streams in the Sultan Marsh. Pseudophoxinus elizavetae, Aphanius marassantensis, Seminemacheilus lendlii and Cobitis sp. coexist in the type locality with Oxynoemacheilus ciceki sp. n.

Abstract  
 A new species in the genus Cheirogaleus is described from Ranomafana and Andringitra national parks, Madagascar. Ranomafana National Park is a rainforest situated in a montane region, and Andringitra National Park is comprised of grassland, lowland and highland forests displaying great altitudinal variation. Both parks are known to harbor wide species diversity in flora and fauna. Genetic and morphometric analyses of the samples collected at these localities confirmed that this Cheirogaleus lineage represents a new species in the C. crossleyi group, and here we elevate it to species status as Cheirogaleus grovesi, for the British-Australian biological anthropologist, evolutionary biologist and taxonomist Colin Groves.

Key Words: Cheirogaleus, dwarf lemur, cryptic species, Madagascar

 Cheirogaleus grovesi
 Formerly Cheirogaleus sp. nov. 2, also CCS3/Crossleyi D (Lei et al. 2014), 
also Cheirogaleus sp. Ranomafana Andrambovato (Thiele et al. 2013).


Description. The dorsum, limbs, and head are rufous-brown. The areas around the orbits are brownish-black, with a white patch proximal to the fleshy part of the nose in the inter-ocular space. The pelage on the ventral surface of the mandible is white, which continues onto the rufous-grey pelage of the ventrum.

Distribution. Cheirogaleus grovesi is known from the national parks of Ranomafana and Andringitra, as well as surrounding areas, and likely occupies a fragmented range between the two parks across the Haute Matsiatra region of Madagascar. Observed at 754–999 m above sea level (Fig. 3).

Etymology. This species is named for the late British-Australian biological anthropologist, Professor Colin Groves (1942- 2017), in recognition of his more than forty years of work in the fields of primatology, evolutionary biology, morphological analysis, mammalian taxonomy and associated disciplines. Professor Groves embodied the true spirit of collaboration. His fastidious research on historical collections incorporated the work of those that preceded him, which he combined with the efforts of his contemporaries, creating compositions that span hundreds of years of scientific exploration. At the time of his passing, Professor Groves was widely regarded as the greatest living primate taxonomist.

Vernacular Names. Groves’, Andringitra, or Haute Matsiatra dwarf lemur.
