Abstract
We investigated diminutive day geckos (SVL < 40 mm) of the genus Cnemaspis (Cnemaspis kandiana Group) from mainland Sumatra and islands along its western margin (Nias, Siberut, Pagai, and Enggano). The assemblage includes several species based on morphological evidence, five of which we describe as new. The new species occur in the Sumatran provinces of Aceh, North Sumatra, and West Sumatra. Finally, we provide a new key and redescriptions for three previously recognized species: Cnemaspis dezwaani, Cnemaspis modiglianii, and Cnemaspis whittenorum, based on recently collected material, and clarify contradictory information concerning their original descriptions and their key under each species account.

[Botany • 2017] Habenaria yookuaaensis • A New Species (Orchidaceae: Orchidioideae) from Oaxaca, Mexico


Habenaria yookuaaensis 
Mejía-Marín, Espejo, López-Ferr. & R. Jiménez


Abstract

Habenaria yookuaaensis, a new species from the state of Oaxaca, is described and illustrated. The new taxon is part of the H. brevilabiataH. virensH. odontopetalaH. strictissima, and H. acalcarata complex, species with which the new entity is compared.

Keywords: Jamiltepec, Monocots, San Juan Colorado, terrestrial orchid, Mexico


 

Habenaria yookuaaensis Mejía-Marín, Espejo, López-Ferr. & R. Jiménez, sp. nov. (Figs. 1, 2)

Similar to Habenaria brevilabiata Richard & Galeotti (1845: 29), but habit terrestrial, with flowers white-greenish, petals oblong-falcate, and lip acuminate, with two triangular divaricate basal auricles.


Etymology:— The specific epithet refers to the name of San Juan Colorado, place where was found the new taxon, and derives from the Mixtec word “yo’o kua’a” formed by the terms “yo’o” (bejucos, lianas) and “kuaa’a” (rojo, colorado), and means “lugar de tierra colorada” (place of red soil). 

Distribution and Habitat:— Habenaria yookuaaensis is known until now from two localities in the state of Oaxaca. The plants are very scarce and grow between rocks, on moist soils rich in organic matter, under the shade of the trees on the riverbanks. It flowers in September.

[PaleoIchthyology • 2017] Scleropages sinensis • First Complete Fossil Scleropages (Osteoglossomorpha) from the early Eocene, Hubei, China


Scleropages sinensis 
Zhang & Wilson, 2017
Abstract
A new species of osteoglossid fish, Scleropages sinensis sp. nov., is described from the Early Eocene Xiwanpu Formation in Hunan and the Yangxi Formation in Hubei, China. The new species was attributed to Scleropages, an extant genus of Osteoglossidae, because it very closely resembles the genus in skull bones, caudal skeleton, the shape and position of fins, and reticulate scales. The new fish is very similar to extant Scleropages except: the nasals do not appear to be ornamented; the sensory pore in the antorbital is large; the posterior infraorbitals are not quite covering the dorsal limb of the preopercle; the posteroventral angle of the preopercle is produced to point; the posteroventral margin of the opercle is concave and the ventral end of the bone is produced to a point; the pectoral fin is very long and extends well behind the beginning of the pelvic fin; the vertebral count is about 46–48; the parapophyses are shorter and the upper and lower caudal rays are nearly as long as the inner rays. The new fish is closer to its Asian neighbor, S. formosus, than to its southern relative, S. leichardti. Scleropages formosus inhabits natural lakes, swamps, flooded forests, and slowly moving, deep parts of rivers with overhanging vegetative cover. It is a carnivorous fish and its food consists mainly of insects, fishes, worms, small amphibians, small mammals, and even birds. S. sinensis may live in the same natural environment and have a similar diet except for the largest items. Sexual dimorphism may exist in S. sinensis. The presumed male has a slimmer and shallower body, a relatively larger head, and a deeper mouth cleft. The discovery of Scleropages sinensis sp. nov. dates the divergence of Scleropages and Osteoglossum to no later than the Early Eocene.

[Herpetology • 2017] Eleutherodactylus cattus • Cryptic within Cryptic: Genetics, Morphometrics, and Bioacoustics Delimitate A New Species of Eleutherodactylus (Anura: Eleutherodactylidae) from Eastern Cuba

  DOI: 10.11646/zootaxa.4221.5.1 
  
Abstract

We studied the variation in genetics, bioacustics, and morphology in Eleutherodactylus glamyrus, a regionally endemic frog species restricted to high elevations in the Sierra Maestra Massif, Western Cuba that was originally described as a cryptic species hidden under the name E. auriculatus. Genetic analysis of mtDNA sequences of the 16S and cob genes identify two allopatric and strongly supported mitochondrial clades (phylogroups) which also showed no haplotype sharing in the nuclear Rag-1 gene. Bioacustic, and morphological comparisons concordantly identify these two phylogroups as independent evolutionary lineages. Therefore, we herein restrict the name Eleutherodactylus glamyrus Estrada and Hedges to populations represented in our analyses as the western phylogroup (Cordillera del Turquino to Pico La Bayamesa) and consider specimens from the eastern phylogroup (Sierra del Cobre) to represent a new species described and named as Eleutherodactylus cattus. Our results add to the growing list of Eleutherodactylus species endemic to Cuba and highlight the importance of combining different sources of evidence for obtaining robust assessments of species limits in amphibians.

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.

[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.

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.

[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.
