 Abstract
 A new species of potamid crab of the genus Terrapotamon Ng, 1986, is described from karst forests in Satun, Peninsular Thailand. Terrapotamon thungwa n. sp. has very long ambulatory legs and superficially resembles T. longitarsus, the only other long-legged species in the genus. They can easily be distinguished by life colouration, carapace features, as well as structures of the epistome, male thoracic sternum, cheliped and male first gonopod.

Etymology. The name is derived from the type locality at Amphoe Thung Wa. The name is used as a noun in apposition. 

Remarks. The long ambulatory legs of T. thungwa n. sp. is a character shared only by one other species of Terrapotamon, T. longitarsus Lheknim & Ng, 2016, also from the Satun area in Peninsular Thailand. It is surprising to find two similar species occurring in the same area, but the differences between the two species are very marked and leave no doubt they are separate taxa. Terrapotamon thungwa can most easily be separated in its bright red overall coloration in life (Figs. 1, 8A) (purple in T. longitarsus; Fig. 6); ....

Habitat. All the specimens of Terrapotamon thungwa were obtained from the karst landscape of Satun. From the material collected, it would appear that the area and habitat where T. thungwa occurs overlaps with T. longitarsus. Both species were found inside and outside the caves as well as in the karst forest. In the dark zone inside the cave, adults of T. thungwa were observed climbing on the cave walls (Fig. 8B, C), with a small specimen observed in a pool on the cave floor (Fig. 9A, B). Up to five specimens have been observed on the cave floor. Adult males of both two species were observed in rock pools at the bottom of deep crevices in the karst forest, while a small specimen of T. longitarsus were seen at a sheltered rock pool near the cave entrance (Fig. 9C, D). The crabs use these collected pools to replenish their gill chambers.

Abstract
Genuine fossils with exquisitely preserved plumage from the Late Jurassic and Early Cretaceous of northeastern China have recently revealed that bird-like theropod dinosaurs had long pennaceous feathers along their hindlimbs and may have used their four wings to glide or fly. Thus, it has been postulated that early bird flight might initially have involved four wings (Xu et al. Nature 421:335–340, 2003; Hu et al. Nature 461:640–643, 2009; Han et al. Nat Commun 5:4382, 2014). Here, we describe Serikornis sungei gen. et sp. nov., a new feathered theropod from the Tiaojishan Fm (Late Jurassic) of Liaoning Province, China. Its skeletal morphology suggests a ground-dwelling ecology with no flying adaptations. Our phylogenetic analysis places Serikornis, together with other Late Jurassic paravians from China, as a basal paravians, outside the Eumaniraptora clade. The tail of Serikornis is covered proximally by filaments and distally by slender rectrices. Thin symmetrical remiges lacking barbules are attached along its forelimbs and elongate hindlimb feathers extend up to its toes, suggesting that hindlimb remiges evolved in ground-dwelling maniraptorans before being co-opted to an arboreal lifestyle or flight.

Etymology: Serikos, ancient Greek for silk, because the body is almost covered with plumulaceous-like feathers; Ornis, ancient Greek for bird; named in honour of Sun Ge, for his contribution to our knowledge of Jurassic and Cretaceous ecosystems in Asia.

Holotype: PMOL-AB00200 is a single complete articulated skeleton with associated integumentary structures preserved on a slab. The counterpart is missing, but most of the skeleton is preserved on the main slab.

Locality and horizon: PMOL-AB00200 was collected in the Tiaojishan Formation (Oxfordian, Upper Jurassic; Chu et al. 2016) from Daxishan village, Linglongta (Jianchang County, Liaoning Province, China).

Diagnosis: Serikornis is characterized by the following combination of characters (autapomorphies are marked with an asterisk): four anterior maxillary teeth twice as long as the others regarding the crown height*; coracoid tuber well-developed and laterally projected from the lateral margin of the coracoid and forming a subglenoid shelf along the caudoventral margin of the bone; the distal end of the lateral process of the coracoid is thicker than the proximal part and forms a ventral rounded bump; ventrodistal process of ischium narrow, hook-like, strongly deflected caudodorsally and set at the distal end of the ischium*; smooth ventral side of coracoid devoid of small pits.

[Crustacea • 2017] Pseudosesarma glabrum • A New Species of Pseudosesarma Serène & Soh, 1970 (Brachyura: Sesarmidae) from Cochin in southwestern India


Pseudosesarma glabrum Ng, Rani & Nandan, 2017


Abstract

A new species of mangrove sesarmid crab of the genus Pseudosesarma Serène & Soh, 1970, is described from Cochin, southwest India. The species superficially resembles P. edwardsii (De Man, 1887), known from Myanmar and many parts of India; the proportions of the carapace and male pleon also ally it with P. crassimanum (De Man, 1887) from Myanmar, Sri Lanka and Southeast Asia. Pseudosesarma glabrum n. sp., however, is easily separated from P. edwardsii and P. crassimanum primarily by the almost glabrous dorsal surface of the carapace and the distinctive form of its male first gonopod.

Abstract
A total of 11 species and 1 subspecies of Alycaeus were recognised in Peninsular Malaysia prior to this study. However, these taxonomic descriptions of Alycaeus taxa were based on limited numbers of examined materials, where a whole spectrum of morphological variations were not accounted for and diagnoses were often provided without sufficient comparison between congeners from across the peninsula. We reviewed Peninsular Malaysian Alycaeus through the examination of 5137 specimens in 522 collection lots from all major museum collections and literature sources. Based on these examined materials, we utilised a more comprehensive revised set of 39 shell and operculum characters, as well as living animal colour to describe all Alycaeus species in this paper. We also noted their habitat and ecology, as well as updated the distribution of each species. Of the 12 previously described taxa, 10 are reconfirmed as present on Peninsular Malaysia (Alycaeus balingensis, Alycaeus carinata, Alycaeus conformis, Alycaeus gibbosulus, Alycaeus kapayanensis, Alycaeus kelantanensis, Alycaeus liratulus, Alycaeus perakensis perakensis, Alycaeus perakensis altispirus and Alycaeus thieroti) and 2 are confirmed as absent from the peninsula (Alycaeus jagori and Alycaeus pyramidalis). A new record of Alycaeus robeleni is reported for Peninsular Malaysia. One species, Chamalycaeus jousseaumei is confirmed as present on the peninsula and is reassigned to Alycaeus. The subspecies Alycaeus perakensis altispirus Möllendorff, 1902, is elevated to species. Examined Peninsular Malaysian materials that do not fit previously recognised species are described as new species. A total of 11 new species are proposed (Alycaeus selangoriensis sp. n., Alycaeus costacrassa sp. n., Alycaeus ikanensis sp. n., Alycaeus alticola sp. n., Alycaeus charasensis sp. n., Alycaeus kurauensis sp. n., Alycaeus regalis sp. n., Alycaeus virgogravida sp. n., Alycaeus senyumensis sp. n., Alycaeus expansus sp. n., Alycaeus clementsi sp. n.). Overall, 23 species of Alycaeus are now recognised in Peninsular Malaysia.

[Herpetology • 2017] Theloderma pyaukkya • A New Cryptic Species of the Theloderma asperum Complex (Anura: Rhacophoridae) from Myanmar


Theloderma pyaukkya Dever, 2017


Abstract
I describe a new species of Theloderma from two regions in Myanmar (Chin State in western Myanmar and Kachin State in northern Myanmar). Highly similar in appearance and size to Theloderma albopunctatum and Theloderma asperum, the new species differs by the presence of small, bilateral vocal sac openings absent in T. albopunctatum and T. asperum. Molecular phylogenetic analysis from two mitochondrial and four nuclear gene fragments infers that individuals are members of a unique genetic lineage within the T. asperum Complex.

Abstract

Numerous specimens of squat lobsters belonging to the families Munididae, Munidopsidae and Eumunididae were collected during several cruises along the eastern coasts of Africa. The study of these specimens revealed the presence of 10 new species (one Eumunida Smith, 1883, eight Munida Leach, 1820 and one Munidopsis Whiteaves, 1874). We describe and illustrate these new species, providing some new data on occurrences and colour patterns for previously described taxa. We have also included molecular data from two mitochondrial markers (16S rRNA and COI) to support the taxonomic status of different species. Some deep-sea species show a clear increase in their geographic range distribution. Finally, a key to known species of the genus Munida from the western and central Indian Ocean is also presented.

[Entomology • 2017] Dendrobia gen. nov. • A New Genus and other New Species of Agraeciini (Orthoptera: Tettigoniidae; Conocephalinae) from the Eastern Arc Mountains, East Africa


Dendrobia amaniensis  
Hemp, Ingrisch & Heller, 2017


Abstract

The genus Dendrobia n. gen. is erected to include Dendrobia amaniensis n. sp. from the East Usambara Mountains as type species. A second species in this genus, Dendrobia octopuncata n. sp., is described from the Udzungwa Mountains of Tanzania. Dendrobia n. gen. is a canopy dweller found only high up on trees in closed submontane and montane forest. The peak frequency of its song is lower than in all other known African Agraeciini, correlating with the large resonant areas in the tegmina. Two new Afroanthracites species, Afroanthracites ngologolo n. sp. and Afroanthracites nguru n. sp. are described from the Eastern Arc Mountains in Tanzania. These species are dwellers of understory vegetation in closed forest in the Udzungwa and Nguru Mountains respectively.

[Herpetology • 2017] Nasikabatrachus bhupathi • A New Species of the Genus Nasikabatrachus (Anura, Nasikabatrachidae) from the eastern Slopes of the Western Ghats, India


Nasikabatrachus bhupathi 
Janani, Vasudevan, Prendini, Dutta & Aggarwal, 2017

We describe a new species of the endemic frog genus Nasikabatrachus, from the eastern slopes of the Western Ghats, in India. The new species is morphologically, acoustically and genetically distinct from N. sahyadrensis. Computed tomography scans of both species revealed diagnostic osteological differences, particularly in the vertebral column. Male advertisement call analysis also showed the two species to be distinct. A phenological difference in breeding season exists between the new species (which breeds during the northeast monsoon season; October to December), and its sister species (which breeds during the southwest monsoon; May to August). The new species shows 6 % genetic divergence (K2P) at mitochondrial 16S rRNA (1330 bp) partial gene from its congener, indicating clear differentiation within Nasikabatrachus. Speciation within this fossorial lineage is hypothesized to have been caused by phenological shift in breeding during different monsoon seasons—the northeast monsoon in the new species versus southwest monsoon in N. sahyadrensis. It is postulated that proximate triggers of breeding behavior and highly stenotopic adaptation of Nasikabatrachus tadpoles to inhabit cascades during monsoonal stream flows, have led to allopatry on the eastern and western slopes of the Western Ghats, thereby promoting speciation in this ancient genus.

[Paleontology • 2017] Shringasaurus indicus • A New Horned and Long-necked Herbivorous Stem-Archosaur from the Middle Triassic of India


Shringasaurus indicus 
Sengupta, Ezcurra & Bandyopadhyay, 2017

   DOI: s41598-017-08658-8 

Abstract
The early evolution of archosauromorphs (bird- and crocodile-line archosaurs and stem-archosaurs) represents an important case of adaptive radiation that occurred in the aftermath of the Permo-Triassic mass extinction. Here we enrich the early archosauromorph record with the description of a moderately large (3–4 m in total length), herbivorous new allokotosaurian, Shringasaurus indicus, from the early Middle Triassic of India. The most striking feature of Shringasaurus indicus is the presence of a pair of large supraorbital horns that resemble those of some ceratopsid dinosaurs. The presence of horns in the new species is dimorphic and, as occurs in horned extant bovid mammals, these structures were probably sexually selected and used as weapons in intraspecific combats. The relatively large size and unusual anatomy of Shringasaurus indicus broadens the morphological diversity of Early–Middle Triassic tetrapods and complements the understanding of the evolutionary mechanisms involved in the early archosauromorph diversification.

Shringasaurus indicus gen. et sp. nov.

Etymology: Śṛṅga’ (Shringa), horn (ancient Sanskrit), and ‘sauros’ (σαῦρος), lizard (ancient Greek), referring to the horned skull; ‘indicus’, Indian (Latin English), refers to the country where such species was discovered.

Holotype: ISIR (Indian Statistical Institute, Reptile, India) 780: partial skull roof (prefrontal, frontal, postfrontal, and parietal) with a pair of large supraorbital horns (Fig. 2e,i).

Locality and horizon: Near Tekapar village, Hoshangabad district, Madhya Pradesh, India (Fig. 1); Denwa Formation, Anisian, early Middle Triassic18, Satpura Gondwana Basin.

Diagnosis: Relatively large (3–4 m total body length; Fig. S1) allokotosaurian archosauromorph that differs from other stem-archosaurs in the following combination of character-states: confluent external nares; pair of anterodorsally oriented supraorbital horns; similar sized and leaf-shaped marginal and palatal teeth with large denticles; middle-posterior cervical, dorsal, and at least the first two caudal vertebrae with mammillary processes on the neural spines; middle-posterior cervical, dorsal, and sacral vertebrae with hyposphene-hypantrum accessory articulations; cervical vertebrae 2–5 with epipophyses (unknown in Cv6); dorsal vertebrae with spinoprezygapophyseal and spinopostzygapophyseal laminae; dorsal vertebrae 1–12 with spinodiapophyseal laminae; anterior dorsal vertebrae with neural spines two times taller than its respective centrum (see Supplementary Information for differential diagnosis).

Abstract
A new species of clearwing moth, Pyrophleps ellawi Skowron Volponi, sp. n., is described from Peninsular Malaysia. Information on the habitat, time and conditions of occurrence, flight and mud-puddling behaviour, functional morphology, and DNA barcode are also provided. Photographs and a supplementary video from the wild demonstrate the postures and behaviour of this species of Pyrophleps, whose remaining members were described only on the basis of pinned specimens. This is the first record of this genus in Peninsular Malaysia.

Keywords: Sesiidae, clearwing moth, Pyrophleps ellawi, mimicry, mud-puddling, behaviour, Malaysia

Diagnosis: The new species is superficially most similar to Pyrophleps vitripennis, from which it can easily be distinguished by the configuration of male genitalia (compare Fig. 4 herein with Arita and Gorbunov 2000, fig. 6), presence of hair-like scales on labial palpi (smoothly scaled in species compared), presence of orange hair-like scales on fore- and mid tibiae and lack of orange scales on wings, broader external transparent area of forewing. Apart from morphological features, P. ellawi shows 8% COI sequence divergence from P. vitripennis (Table 1). Based on genitalia configuration, this species is most similar to P. nigripennis. However, it differs in the shape of the valva and gnathos. Besides that, it can immediately be distinguished by the well-developed transparent areas of forewing (compare Fig. 3 herein with Arita and Gorbunov 2000, fig. 8), narrow discal spot on hindwing and by the colouration of the hind leg tuft (extensive red both externally, on tibia, and internally, on tibiae and tarsi, in P. nigripennis). From P. ruficrista it differs in more developed forewing ATA and PTA and less developed ETA and in the hind leg tuft (cinnabar red with two black spots and patches of blue scales in P. ruficrista). From P. cruentata, P. haematochrodes , P. cucphuonganae and P. bicella, it can be distinguished by the entirely transparent hindwings and absence of red scales on wings and abdomen.

Etymology: The species is named after our dear friend El Law, a dedicated conservation activist with sincere sensibility for Malaysian nature who, over the years of our studies on Malaysian Sesiidae, offered us his help in countless aspects.

Distribution and habitat: In addition to the type locality, the species is known also from the Taman Negara National Park, Malaysia, where it was observed and filmed in two locations approx. 50 km from each other. All observations were done on sandy and pebble river banks exposed to sunlight, in a lowland dipterocarp forest (Fig. 5)

Conclusion: 
The new wasp-mimicking species of Sesiidae, Pyrophleps ellawi, represents the first record of the genus Pyrophleps in Peninsular Malaysia and the first filmed in the wild. The video realized in its habitat provided valuable information on its authentic habitus, functional morphology, and behaviour.
