Abstract

A new species of pterosaur, Maaradactylus kellneri gen. nov., sp. nov. (Archosauria: Pterosauria) from the Romualdo Formation (Aptian/Albian), is herein described. The specimen (MPSC R 2357) was found at Sítio São Gonçalo, Santana do Cariri city (State of Ceará, northeast Brazil) and consists of the skull, atlas and axis, and represents one of the largest skulls of the Anhangueridae from the Araripe Basin described. The autapomorphies of the new pterosaur include the following characters: a premaxillary sagittal crest that is relatively long and high, beginning at the anterior part of the skull (rostrum) and extending to the 22nd pair of alveoli, not covering the nasoantorbital fenestra or the choanaes, and also the presence of 35 pairs of alveoli; smooth palatal ridge, which starts on the 5th pair of alveoli and ends on the 13th pair; palate is convex shaped in the anterior region; choanae not extending laterally; small and convex palatal elevation; the 5th, 6th and 7th alveoli smaller than the 4th and 8th; the alveoli decreasing in size from the 9th to the 12th and increasing from the 13th to 18th, and from the 18th to the 35th they are arranged in triplets. Furthermore, the lateral surface of the premaxillary crest shows grooves and tridimensional structures that may have housed blood vessels.

Keywords: Pterosauria, Anhangueridae, Araripe Basin, Romualdo Formation, Brazil





The generic name refers to Maara, in the legends of the Cariri the daughter of a chief, by sorcery changed into a river monster with long teeth, devouring fishermen. The suffix ~dactylus is common in the names of pterosaurs and is derived from Greek δάκτυλος, daktylos, "finger", referring to the long (fourth) wing finger. The specific name honours Alexander Kellner, Brazil's foremost pterosaur expert.

(Reserva científica de la Caldera de San Carlos, 3°14’2.39”N, 8°37’38.60”E.).

Abstract
The gecko Hemidactylus fasciatus is widespread in rainforest regions of equatorial Africa, from Guinea to Cameroon. Recently, this taxon was identified as a cryptic complex of at least five species, using multilocus genetic data and coalescent models for species delimitation. Here, we provide the formal descriptions of four new species from tropical West and Central Africa. As typical for cryptic species, the new species are genetically distinct, but difficult to distinguish using external morphology. However, coloration, shape of the body crossbands, and body size, are important distinguishing characters for this complex.

We provide a new taxonomy for this complex that includes the following forest gecko species: H. fasciatus is now restricted to West Africa occurring eastwards to the Dahomey Gap, Hemidactylus kyaboboensis sp. n. is known only from within the Dahomey Gap, H. eniangii sp. n. is distributed from the Dahomey Gap to western Cameroon, H. coalescens sp. n. occurs from central Cameroon to southern Gabon, H. biokoensis sp. n. is restricted to Bioko Island, and H. ituriensis, herein recognized as full species, is known from several localities in eastern Africa.

Key words: Africa, rainforest, Sauria, Gekkonidae, Hemidactylus fasciatus complex, Hemidactylus ituriensis.

Posterior probabilities are shown on branches. Museum specimen records were downloaded from the HerpNET database, and geographic distribution was predicted using Maxent. Populations with uncertain taxonomic placement are indicated with “?”. Type localities are: [A]= H. kyaboboensis sp. n.; [B]= H. eniangii sp. n.; [C]= H. biokoensis sp. n.; and [D]= H. coalescens sp. n.

[Ichthyology • 2014] Rhinobatos whitei • A New Shovelnose Ray (Batoidea: Rhinobatidae) from the Philippine Archipelago


Rhinobatos whitei 
Last, Corrigan & Naylor, 2014
 DOI: 10.11646/zootaxa.3872.1.3

Abstract
A new shovelnose ray, Rhinobatos whitei sp. nov., is described from material collected at fish markets of the southern Philippines. This ray was first formally indentified as an undescribed species more than a decade ago as part of a WWF funded survey of sharks and rays of the Philippines. It was considered to be most closely related to another shovelnose ray found nearby in the western North Pacific, R. schlegelii, but differs from that species in body shape and aspects of coloration, meristics and morphometry. It differs from all other shovelnose rays of the region in its NADH2 sequence, clustering together with an Indonesian species R. jimbaranensis, and another undescribed species from Borneo.

[Orchidology • 2014] Paphiopedilum rungsuriyanum • A New Species of Paphiopedilum discovered in northern Laos


Paphiopedilum rungsuriyanum
O. GRUSS, N.RUNGRUANG, Y. CHAISURIYAKUL et I. DIONISIO
A new and very distinct species of the genus Paphiopedilum from north-Laos 

In the last few years, a large number of plants of the genus Paphiopedilum as well as other species, came from Laos on the market in Thailand. Frequently in the past few months, a number of very small size plants of the genus Paphiopedilum appeared as Paph. canhii in the trade. Niwat RUNGRUANG, a grower from Thailand also received a number of plants from these collections and when the plants came to bloom in May 2014, he was surprised because he realized that these Paphs were not Paph. canhii. Therefore Niwat RUNGRUANG sought contact with slipper orchid specialists in Thailand and Germany and asked for an analysis and identification of the plants, based on several Iowering plants and detailed picture material (in particular by Olaf Gruß in Germany). 
While the plants with their marbled leaves appear quite similar to Paph. canhii, the blossom at first glance clearly show much broader petals an intensive red-purple coloring, as well as an entirely different staminodium. Also the underside of the leaves differs significantly in the new species. While Paph. canhii is rather red- purple speckled, this new species shows a gray green bottom with wide purple veins.

the naming is in honor of Niwat RUNGRUANG in the 2rd part of his name, but also means rung = flowering period, success, prosperity and Suriya = growing, increasingly

Oedura murrumanu sp. nov. in the Oscar Range. Photograph—P. Oliver.

Abstract
We describe a new species of large Oedura from the Oscar Range on the southern edge of the Kimberley Craton in north-western Australia. Oedura murrumanu sp. nov. can be distinguished from all congeners by the combination of large size (snout-vent length to 103 mm), moderately long and slightly swollen tail, tiny scales on the dorsum, fringe of laterally expanded lamellae on each digit, and 6–7 paired distal subdigital lamellae on the fourth toe. The new species is the first endemic vertebrate known from the limestone ranges of the southern Kimberley; however, this area remains poorly surveyed and further research (particularly wet season surveys and genetic analyses) is required to better characterise regional biodiversity values.

Keywords: Australian Monsoonal Tropics, endemism, lizard, mesic refigia, Oscar Range, saxacoline


Oedura murrumanu sp. nov.
Limestone Range Velvet Gecko

Etymology. ‘Murru manu(‘u’ pronouced as ‘oo’) is the word for gecko in the language of the Bunuba people of the south-west Kimberley. This new species is probably entirely restricted to the traditional lands of the Bunuba. 
Distribution. All museum and sight records are from around the type locality (Fig. 1). Further survey work is required to determine if it occurs elsewhere in the Oscar Range, however, there are no obvious barriers between the type locality and large areas of similar limestone to the east, west and north.

Ecology. The type series of O. murrumanu sp. nov. was collected towards the start of the ‘wet season’ (late October) following a brief rain shower. Individuals were observed on horizontal rock platforms and associated with deep horizontal crevices among smooth, weathered limestone (Fig. 7). Several were observed drinking water that had pooled on the rocks. The single adult female paratype (WAM R176699) contains well-developed eggs (approximately 10 mm in diameter and shelled), suggesting that at least some egg-laying occurs early in the wet season. Other geckos recorded at the same time and place were Gehyra cf. multiporosa, Heteronotia planiceps, and Nephrurus sheai.
At the same locality in the late wet season (late February, 2013) several individuals were observed in inaccessible spots on limestone pillars, and one further individual was observed on lower rocks as it appeared to be stalking smaller Gehyra species (G. Gaikhorst, pers. comm.).

Grey bars at right denote maximum body size for each species (in mm), with grey shading denoting larger-bodied clades in Asian and Australopapuan regions.


Abstract
The region between the Asian and Australian continental plates (Wallacea) demarcates the transition between two differentiated regional biotas. Despite this striking pattern, some terrestrial lineages have successfully traversed the marine barriers of Wallacea and subsequently diversified in newly colonized regions. The hypothesis that these dispersals between biogeographic realms are correlated with detectable shifts in evolutionary trajectory has however rarely been tested. Here, we analyse the evolution of body size in a widespread and exceptionally diverse group of gekkotan lizards (Cyrtodactylus), and show that a clade that has dispersed eastwards and radiated in the Australopapuan region appears to have significantly expanded its body size ‘envelope’ and repeatedly evolved gigantism. This pattern suggests that the biotic composition of the proto-Papuan Archipelago provided a permissive environment in which new colonists were released from evolutionary constraints operating to the west of Wallacea.

[Paleontology • 2014] Tachiraptor admirabilis • New Dinosaur (Theropoda, stem-Averostra) from the earliest Jurassic of the La Quinta Formation, Venezuelan Ande


Tachiraptor admirabilis, unearthed in Venezuela, attacking the herbivorous dinosaur Laquintasaura.
PaleoArt: Maurílio Oliveira | DOI: 10.1098/rsos.140184

Abstract 
Dinosaur skeletal remains are almost unknown from northern South America. One of the few exceptions comes from a small outcrop in the northernmost extension of the Andes, along the
western border of Venezuela, where strata of the La Quinta Formation have yielded the ornithischian Laquintasaura venezuelae and other dinosaur remains. Here, we report isolated bones (ischium and tibia) of a small new theropod, Tachiraptor admirabilis gen. et sp. nov., which differs from all previously known members of the group by an unique suite of features of its tibial articulations. Comparative/phylogenetic studies place the new form as the sister taxon to Averostra, a theropod group that is known primarily from the Middle Jurassic onwards. A new U–Pb zircon date (isotope dilution thermal-ionization mass spectrometry; ID-TIMS method) from the bone bed matrix suggests an earliest Jurassic maximum age for the La Quinta Formation. A dispersal–vicariance analysis suggests that such a stratigraphic gap is more likely to be filled by new records from north and central Pangaea than from southern areas. Indeed, our data show that the sampled summer-wet equatorial belt, which yielded the new taxon, played a pivotal role in theropod evolution across the Triassic–Jurassic boundary

Tachiraptor admirabilis new genus and species

Etymology: The generic name derives from Táchira, the Venezuelan state where the fossil was found, and raptor (Latin for thief), in reference to the probable predatory habits of the animal. The specific epithet honours Simon Bolivar’s ‘Admirable Campaign’, in which La Grita, the town where the type locality is located, played a strategic role.

Branch colours represent extension of ghost lineages in millions of years (red, less than 15; purple, 15–35; blue, more than 35). Taxon bar lengths correspond to their chronologic distribution/uncertainty (based on various sources). Bar colours match those of the index Middle Jurassic palaeomap [70] and correspond to the provenance of Triassic/Jurassic theropods from the defined palaeobiogeographic provinces (SG, South Gondwana; EA, Euramerica; TU, Transurals; EB, Equatorial Belt) at the time of their occurrences.

Abstract
 The type species of the genus Amynthas Kinberg, 1867 was re-investigated using type specimens from Biozentrum Grindel und Zoologisches Museum, University of Hamburg and Swedish Museum of Natural History. Also we described four new species of the genus Amynthas from Thailand, two species of the aelianus species group, namely Amynthas arenulus Bantaowong & Panha, new species, and A. longicaeca Bantaowong & Panha, new species, and two species of the corticis species group, A. thakhantho Bantaowong & Panha, new species, and A. phucheefah Bantaowong & Panha, new species, Amynthas arenulus and A. thakhantho occur in sandy habitats of dry dipterocarp and deciduous forest, respectively, and especially in the modified highland paddy fields, while the following two species, A. longicaeca and A. phucheefah occur in deciduous forest reserve areas in clay–rich topsoil.
Key words. Amynthas, Clitellata, systematics, biodiversity, Thailand


ไส้เดือนยักษ์สุรินทร์ | Amynthas arenulus Bantaowong & Panha, new species

Etymology. The specific epithet is from the Latin for a sandy place. This refers to the find-grained sandy area modified as a highland rice paddy system, which is the habitat of the new species.
Distribution. Surin, Sisaket and Ubon Ratchathani.
Habitat. The species lives in the sandy top soil at about 20–30 cm depth, in a highland paddy system modified from dipterocarp forest. Some forest patches are still present near the paddy fields.


ไส้เดือนป่าเต็งรังชัยภูมิ | Amynthas longicaeca Bantaowong & Panha, new species

Etymology. This species was named after the characteristic long intestinal caeca.
Distribution. The new species is known only from the type locality. 
Habitat. Top soil at about 20 cm depth in the dipterocarp forest at elevation 660 meters of Phu Lan Kha National Park, Chaiyaphum, at pH 7, silt loam soil.


ไส้เดือนยักษ์ภูชี้ฟ้า | Amynthas phucheefah Bantaowong & Panha, new species

Etymology. This species was named after the type locality, Mt. Phu Chee Fah.
Distribution. The new species is known only from the type locality. Our collections in nearby areas have also found some earthworm species of the genus Metaphire.
Habitat. The new species exhibited swarming in October 2008 at 1,205 m asl, and most of them were juveniles. The reason is still unknown. We collected some specimens by chance. The worms emerged from the top soil of deciduous forest and tried to migrate across a road to another side of 
the mountain.


ไส้เดือนยักษ์ท่าคันโท | Amynthas thakhantho Bantaowong & Panhanew species
Etymology. This species was named after Tha Khantho, Kalasin, the type locality of the new species.
Distribution. The new species is known only from the type locality.
Habitat. Top soil at about 15 cm depth, at pH 7, loamy soil. Worms produce columnar or tower-like castings about 20 cm high and 4 cm diameter.

[Onychophora • 2013] Eoperipatus totoro • A New Species of Eoperipatus (Onychophora) from southern Vietnam, reveals novel morphological characters for the South-East Asian Peripatidae

the first velvet worm to be described from Vietnam. Velvet worms spit glue from two glands to entangle their prey

Abstract
Although representatives of Peripatidae are widely distributed in South-East Asia, only three valid species of Eoperipatus and one species of Typhloperipatus have been described from this region. According to previous reports, the three species of Eoperipatus show little morphological variation and are difficult to distinguish from each other. In this study, we describe a new species of Eoperipatus from Vietnam, E. totoro sp. nov., using morphological (light and scanning electron microscopy) and molecular data (mitochondrial COI and 12S rRNA sequences). A comparison with specimens of an undescribed species of Eoperipatus from Thailand revealed novel species-specific characters, including the characteristics of male crural complexes, distinct types of scales on the ventral body surface, the inner structure of the circular pits on the male genital pad, and the position and size of the anal gland pads in males. The results of our molecular analyses correspond with those of morphological studies. In contrast to previous assumptions, our findings suggest a high diversity of the South-East Asian Peripatidae, which requires further exploration.

Photograph by Ofelia Mejía-Egas.

Abstract
Vampyressa melissa is a poorly known phyllostomid bat listed as vulnerable by the International Union for Conservation of Nature (IUCN). Since its description in 1926, fewer than 40 V. melissa have been reported in the literature, and less than half of these may have been correctly identified. During revisionary studies of Vampyressa, we uncovered two previously unrecognized species related to V. melissa, all associated with higher elevation habitats (>1400 m), one from the Andes of Colombia (Vampyressa sinchi, new species) and the other from western Panama (Vampyressa elisabethae, new species) revealing that V. melissa, as traditionally defined, is a composite of at least three species. In this paper, we provide a restricted diagnosis for the genus Vampyressa, an emended diagnosis of V. melissa, and descriptions of the two new species. The separation of these frugivorous bats, previously identified as V. melissa, into three isolated upper-elevation species, each having restricted distributions further highlights their fragile conservation status.


Vampyressa sinchi, new species
Quechuan Yellow-eared Bat

Distribution: Know only from the type series from the eastern slope of the Central Cordillera (Llorente) and eastern slopes of the Eastern Cordillera (San Juan de Villalobos and Parque Nacional Cueva de los Guácharos) of the Andes in Colombia (fig. 3).

Etymology: A Quechuan word, sinchi conveys the meaning “robust and strong.” The name honors the Quechuan people of Colombia (the Ingas), and indicates the robustness of this species, the largest Vampyressa known. The name is to be treated as a noun in apposition.


Vampyressa elisabethae, new species
Elisabeth’s Yellow-eared Bat

Distribution: Know only from provincia de Bocas del Toro, Panama (fig. 3).

Etymology: The name elisabethae honors the legacy of the late Elisabeth Klara Victoria Kalko in the study of the natural history, ecology, conservation, vocal recognition, and behavior of bats.

Abstract
A new freshwater crab is described from a montane area in northern Taiwan based on morphological characters and molecular evidence. Geothelphusa cilan sp. nov., from the Cilan Forest, situated on the boundary of Hsinchu and Yilan (= Ilan) counties, is close to G. monticola Shy, Ng & Yu, 1994, and G. takuan Shy, Ng & Yu, 1994, but can be distinguished by its male first gonopod (G1) and the ratio of thoracic sternites. Molecular evidence from mitochondrial cytochrome oxidase subunit I (COI) also supports the identity of the new species.
