Abstract

Bats belongs to Pteropodidae Family that spreaded evenly in Indonesia. Genus Rousettus have their morphological variances among its own species based on characteristics on each species. Among them there is fruit-feeding bats of from genus Rousettus (Chiroptera: Pteropodidae) that have many variances of morphology among its own species. This study was aimed to identify the morphological variations and its sex type influence of genus Rousettus bats from Gunung Duasudara Sanctuary, North Sulawesi. The locations were consisted 7 types of major vegetations at altitude range from 0 to 1351 m above sea level (asl). All habitat types were observed using Mist-net method at 1 and 3 m above the ground. There were found 452 individuals, including R. amplexicaudatus (224), R. celebensis (219) and R. tangkokoensis n. sp. (9). Nine individuals of Rousettus tangkokoensis n. sp. were newly found in lowland forest and coastal forest. These newly-found species were different from other Rousettus. There was discovered that sex type had influenced the skull and external body characters on R. amplexicaudatusRtangkokoensis n. sp. R. celebensis. However, most of other characters were statistically not-significant that indicated there was not any sexual dimorphism. According to the Discriminant Function Analysis (DFA), these morphological groups possess different specification. Therefore, the three species of genus Rousettus have statistically variation of skull and external body characters one to another.

Hyphessobrycon petricolus 
Ohara, Lima & Barros, 2017

Abstract
A new species of Hyphessobrycon is described from the rio Roosevelt, rio Madeira basin, Mato Grosso State, Brazil. Hyphessobrycon petricolus sp. n. can be distinguished from its congeners by the unique combination of the following features: a well-defined, relatively narrow dark midlateral stripe on body extending from immediately behind posterior margin of opercle to the middle caudal-fin rays, relatively conspicuous humeral blotch, and 16–20 branched anal-fin rays. Comments on the remaining Hyphessobrycon species presenting a conspicuous dark midlateral stripe are presented.

FIGURE 3. Hyphessobrycon petricolus, paratypes, immediately after capture. 

Sexual dimorphism. Bony hooks on fins, a common dimorphic feature in characids (Malabarba & Weitzman, 2003), were not found in any specimens of Hyphessobrycon petricolus.

Distribution. The new species is so far only known from its type locality, a small tributary of the middle rio Roosevelt, rio Aripuanã drainage, rio Madeira basin, northwestern Mato Grosso State, Brazil (Fig. 4).

Ecological notes. The type locality of Hyphessobrycon petricolus is a small, black water stream 1.5–4 m wide and 0.3–1.5 m deep, with swift water current, and rocky bottom (Fig. 5a), upstream a large waterfall (Fig. 5b). The stream run across a small cerrado-vegetation enclave situated within Amazon forest. Individuals of Hyphessobrycon petricolus were captured near of surface during the night in small groups of 2 to 4 individuals. Other species sampled syntopically were: Aequidens sp., Erythrinus erythrinus, Pyrrhulina sp., Synbranchus sp. and Tatia cf. brunnea

Etymology. The specific name petricolus derives from the Latin petra meaning rock and colus, to abide, to dwell, referring to the occurrence of the species in a rocky-bottomed stream. An adjective.

[Arachnida • 2017] On the New Monotypic Wolf Spider Genus Ovia gen. nov. (Araneae: Lycosidae, Lycosinae)


Ovia procurva Yu & Song, 1988

Abstract

A new monotypic wolf spider genus, Ovia gen. nov. is proposed to accommodate a misplaced species: Pardosa procurva Yu & Song, 1988. Ovia procurva comb. nov. is redescribed, illustrated and designated as the type species for the genus. The subfamily placement of the new genus is discussed and it is considered as a member of Lycosinae Sundevall, 1833 and possibly closely related to Alopecosa Simon, 1885. The presence of an apical process (spur) on the median apophysis is proposed as the putative synapomorphy of Ovia gen. nov. The possible sister-taxon relationship of Ovia gen. nov. with Alopecosa is discussed and evidence on the occurrence of sexual dimorphism and mating plug within the genus are presented. Ovia gen. nov. is assumed to be of Holarctic origin, from which it has migrated to the Indomalayan region. Additionally, a current distribution map for the genus is provided.

Keywords: Araneae, Indomalayan region, mating plug, sexual dimorphism, taxonomy, transfer

[Herpetology • 2016] Celestus laf • A New Species of Celestus (Squamata: Anguidae) from western Panama


Celestus laf  
Lotzkat, Hertz & Köhler, 2016   

Abstract
 We describe the second specimen of the anguid genus Celestus collected in Panama as representative of a new species. The holotype of this new taxon was collected in the Reserva Forestal La Fortuna, about halfway between the type localities of the Panamanian endemic C. adercus and the Costa Rican endemic C. orobius. The new form is most similar to these two species, but differs from them and all other Mesoamerican congeners in scalation and coloration. 

Key Words: Cryptozoic diversity, endemism, Lower Central America, Reserva Forestal La Fortuna, Talamancan highlands 


    

Etymology: The specific name is composed of the initials of the “Lost and Found” ecohostel and given in appreciation of the type locality. Ever since their first visit, which occurred at the beginning of their respective Ph.D. projects in May of 2008, Andreas Hertz and Sebastian Lotzkat have benefited greatly from the exceptional hospitality they always experienced at the ecohostel, and were happy to use its facilities as a convenient base for their herpetological explorations of the La Fortuna Forest Reserve and other areas nearby. Through this mutual partnership, the beautifully situated and by now widely known cloud forest lodge has contributed significantly to our herpetodiversity research in western Panama, and we are glad to honor this exceptional venture by dedicating the second new species we found on its grounds to it, well-timed in its 10th anniversary year.

Abstract 
The genus Neolissochilus was described by Rainboth, 1985 and currently includes 24 nominal taxa with distributions in southern and south-eastern Asia. Five new species of Neolissochilus are described herein from streams and rivers of the Western Ghats, peninsular India, one of the World’s hotspots of biodiversity. The new species include Neolissochilus capudelphinus, N. minimus, N. micropthalmus, N. acutirostris and N. tamiraparaniensis. Neolissochilus wynaadensis (Day, 1873), also from the Western Ghats is considered a valid species. The five new species are described based on meristic, morphometric characters, and molecular data. Relationships among the newly described species and the relationships of Neolissochilus with Systomus (=Barbodes /Puntius), Hypselobarbus Bleeker and Tor Gray, all presumed closely related lineages are discussed.

[Herpetology • 2016] Anolis purpuronectes • A New Species of Semiaquatic Anolis (Squamata: Dactyloidae) from Oaxaca and Veracruz, Mexico


Anolis purpuronectes 
Gray, Meza-Lázaro, Poe & Nieto-Montes de Oca, 2016  

Abstract  

We describe a new species of semiaquatic Anolis (Anolis purpuronectes) from the Chimalapas region of eastern Oaxaca and adjacent Veracruz, Mexico, and investigate its phylogenetic relationships with the closely related species A. barkeri to which the populations under investigation have previously been assigned to. Anolis barkeri and the new species appear to be allopatric, and differ primarily in male dewlap colour (red and orange in A. barkeri, pale purple in A. purpuronectes). A partitioned Bayesian analysis of the mitochondrial genes encoding ND1 (part), ND2, and the intervening tRNAs revealed that A. barkeri and A. purpuronectes are genetically distinct (uncorrected genetic distance between them=11.5%), nested within the A. schiedii group as sister species, and most closely related to a clade composed of A. cymbops, A. milleri, and A. parvicirculatus.

Key words: Anole, Anolis barkeri, Anolis schiedii group, Chimalapas, Mexico, new species, semiaquatic lizard 



 

Etymology.— The specific epithet purpuronectes, a noun in apposition, is a combination of the Latin adjective purpureus (purple) and the Greek noun nektes (a swimmer).

Abstract

We describe a species of Hoolock gibbon (Primates: Hylobatidae) that is new to science from eastern Myanmar and southwestern China. The genus of hoolock gibbons comprises two previously described living species, the western (Hoolock hoolock) and eastern hoolock (H. leuconedys) gibbons, geographically isolated by the Chindwin River. We assessed the morphological and genetic characteristics of wild animals and museum specimens, and conducted multi-disciplinary analyses using mitochondrial genomic sequences, external morphology, and craniodental characters to evaluate the taxonomic status of the hoolock population in China. The results suggest that hoolocks distributed to the east of the Irrawaddy-Nmai Hka Rivers, which were previously assigned to H. leuconedys, are morphologically and genetically distinct from those to the west of the river, and should be recognized as a new species, the Gaoligong hoolock gibbon or skywalker hoolock gibbon (Hoolock tianxing sp. nov.). We consider that the new species should be categorized as Endangered under IUCN criteria. The discovery of the new species focuses attention on the need for improved conservation of small apes, many of which are in danger of extinction in southern China and Southeast Asia.

  Holotype: AMNH M-43068 (adult male, skin only; Figure 3), collected by Roy Chapman Andrews and Yvette Borup Andrews on April 5, 1917 during the American Museum of Natural History's Asiatic Zoological Expedition (Allen, 1938).

 Type locality: Ho-mu-shu (=Hongmushu) Pass, Baoshan, Yunnan, China (25.00 N, 98.83 E).

 Paratypes: AMNH M-43065 (adult female, skin only; Supplemental Figure S1) and MCZ 26474 (=AMNH M-43067, skin and skull, relocated to MCZ in September 1930), collected at the same locality as the holotype (Allen, 1938). IOZ 25965 (adult male, skin and skull; Supplemental Figure S3), collected on 4 June, 1965 at Tengchong, Yunnan, China. MCZ 30383 (adult male, skin and skull; Supplemental Figure S3) collected on 15 January, 1932, ca. 40 miles east of Bhamo, northern Myanmar, during the Brooke Dolan expedition.

 Etymology: Tianxing, meaning heaven's movement or skywalker (xing, movement, can act as either a noun or a verb), a name referring to the unique locomotory mode of gibbons (brachiation; Figure 8) and derived from the text of the I Ching, an ancient Chinese work of divination (“As heaven's movement is ever vigorous, so must the scholarly gentleman (ajp22631-gra-0005, “junzi”) ceaselessly strive for self-improvement”). Gibbons were widely regarded as a symbol of scholar-officials or junzi in ancient China, as the perceived “noble” characteristics of gibbons were considered to accord with the aesthetic taste of both Daoism and traditional Chinese scholars (van Gulik, 1967; Ye & Heule, 2013).



Diagnosis:  Hoolock tianxing is a hoolock gibbon distinguished from other described hoolock species by a combination of external and dental characters. In males, the ventral pelage is brownish, resembling that of H. leuconedys but differing from H. hoolock. The eyebrows are relatively thinner than in H. hoolock and H. leuconedys, and well-separated, differing from the condition in H. hoolock, where there is only a narrow gap between the eyebrows. White hairs are absent in the suborbital area, differing from H. leuconedys, which has white hairs in the suborbital area. The beards of males are black or brown, differing in color from H. leuconedys, which has a whitish or buffy beard, and not as prominent as in H. hoolock. The black, brown or grayish genital tuft in males differs in color from H. leuconedys, which has a white or silvery tuft. The face rings in females are incomplete, differing from the condition in both H. hoolock and H. leuconedys. The crown outline of the lower p4 is oval, making it distinct from H. leuconedys and H. hoolock individuals from Myanmar and more similar to H. hoolock from Assam.

DistributionBetween the Irrawaddy-Nmai Hka River and the Salween River in China and Myanmar. The Dulongjiang valley, the upper tributary of the Nmai Hka River, may serve as a dispersal barrier for hoolocks. Wild individuals are confirmed to occur on Mt. Gaoligong, and historical museum specimens are also known from further south at Gokteik, Shan State, northern Myanmar. Geissmann et al. (2013) estimated that a healthy population with ca. 50,000 individuals of eastern hoolock live in Shan State subtropical forests, and ca. 16,000 individuals live in montane rainforest in Kayah-Kayin.

[Ichthyology • 2017] Molecular based Phylogenetic Species Recognition in the Genus Pampus (Perciformes: Stromateidae) reveals Hidden Diversity in the Indian Ocean



Highlights

• The phylogenetic relationships between Pampus species were determined based on 150 mitochondrial COI gene sequences.
• Morphological and molecular evidence suggests the silver pomfret, reported as Pampus argenteus, distributed in the Bay of Bengal and Arabian sea is distinct from East Asian P. argenteus.
• The silver pomfret in the Indian region represents species with genetic affinity to P. cinereus.
• Hidden species diversity among Pampus species is revealed from Bay of Bengal and Arabian waters.

Abstract
Pomfrets (Genus Pampus) are commercially important fishes in the Indo Pacific region. The systematics of this genus is complicated due to morphological similarities between species. The silver pomfret from Indian waters has long been considered to be Pampus argenteus. The objective of the study was to utilize the mitochondrial COI gene to establish the molecular identity of the silver pomfret distributed in Indian waters and to resolve the phylogenetic relationships among Pampus species in the world based on sequence data in the NCBI database. Seven valid Pampus species are identified in this study. The mean genetic divergence value calculated between clades representing these species was 7.9%. The mean genetic distance between the so-called Pampus argenteus from Indian waters and sequences attributed to P. argenteus from the South China Sea, where the neotype of this species was collected, was found to be greater than 12%, strongly supporting the likelihood of the Indian species being distinct. The Indian Pampus species show very close affinity to P. cinereus, with inter species differences less than 2%. The taxonomic identity of the silver pomfret in India is also discussed here, in light of molecular and morphological evidence.

[Herpetology • 2017] Ameerega shihuemoy • A New Species of Poison-dart Frog (Anura: Dendrobatidae) from Manu Province, Amazon Region of southeastern Peru


Ameerega shihuemoy 
SeRrano-Rojas, Whitworth, Villacampa, Von May, Gutiérrez, Padial & Chaparro, 2017


Abstract

We describe and name a new species of poison-dart frog from the Amazonian slopes of the Andes in Manu Province, Madre de Dios Department, Peru; specifically within the Amarakaeri Communal Reserve and the buffer zone of Manu National Park. Ameerega shihuemoy sp. nov. is supported by a unique combination of characters: black dorsum with cream to light orange dorsolateral lines, blue belly reticulated with black, and the lack of axillary, thigh and calf flash marks. Within Ameerega, it shares the general appearance of A. altamazonica, A. boliviana, A. hahneli, A. ignipedis, A. petersi, A. picta, A. pongoensis, A. pulchripecta, A. simulans, A. smaragdina, and A. yungicola; each possessing a granular black to brown dorsum, a light labial bar, a conspicuous dorsolateral line running from the snout to the groin, and a metallic blue belly and underside of arms and hind limbs. From most of these species it can be distinguished by lacking flash marks on the axillae, thighs, and calves (absent in only A. boliviana and A. smaragdina, most A. petersi, and some A. pongoensis), by having bright cream to orange dorsolateral stripes (white, intense yellow, or green in all other species, with the exception of A. picta), and by its blue belly reticulated with black (bluish white and black in A. boliviana, green and blue with black marbling in A. petersi, and green and blue lacking black marbling in A. smaragdina). Its mating call also shows clear differences to morphologically similar species, with a lower note repetition rate, longer space between calls, and higher fundamental and dominant frequencies. Phylogenetic analyses based on the 16S mitochondrial rRNA fragment also support the distinctiveness of the new species and suggest that Ameerega shihuemoy is most closely related to Ameerega macero, A. altamazonica, A. rubriventris, and two undescribed species (Ameerega sp. from Porto Walter, Acre, Brazil, and Ameerega sp. from Ivochote, Cusco, Peru). Genetically, the new species is most similar to the sympatric A. macero, from which it clearly differs in characteristics of its advertisement call and coloration. The new species is found near rocky streams during the dry season and near temporary water bodies during the rainy season. Tadpoles are found in lentic water along streams, or in shallow, slow-moving streams. Given its small geographic range, we recommend that A. shihuemoy should be considered 'Near threatened' (NT) according to IUCN Red List criteria.

Etymology. The specific name shihuemoy (English pronunciation: shee-way-moy) corresponds to the Harakmbut word for "poison dart frog". The Amarakaeri are aboriginals from Amazonian Peru and their language belongs to the Harakmbut linguistic group. They coexist with the new species.
