Aim: The study was carried out to ascertain whether morphotype of Scomberoides commersonnianus (Talang queenfish) existing along the Indian coast is a new species or not. Methodology: Talang queenfish and the morphotype were tested for their uniqueness using systematic and molecular tools. The morphometric and meristic details including otolith morphometry were analysed and compared for taxonomic divergence and Cytochrome Oxidase I and Cytochrome b gene sequences for quantifying genetic divergences. Results: The systematic analysis indicated significant morphometric differences between both. The otolith morphometry and phylogeny also confirmed the divergence between them, and qualified the morphotype as an independent species status and named Scomberoides pelagicus sp. nov. Interpretation: The new species is distinct by deep ovate body, concave dorsal head profile, anal fin origin anterior to second dorsal fin and pelvic to pectoral fin, helical arrangement of body scale and stout and less numerous gill rakers on the first gill arch. The phylogeny as on Cytochrome b and Cytochrome Oxidase 1 sequences are very distinct, with 11.2% and 2.0% divergence respectively. Their known distributional range are peninsular region of Indian coast, Malaysian region of the South China Sea and Manila Bay, Philippines.

A New Species

Abstract The integrated results of morphological and molecular phylogenetic analyses confirmed the new species status of a recently discovered population of Ansonia from Suan Phueng District, Ratchaburi Province, Thailand. Ansonia karensp. nov. is separated from all other species of Ansonia by a unique combination of mensural, discrete morphological, and color pattern characteristics and is the sister species of A. thinthinae from Tanintharyi Division, Myanmar. This discovery fills a geographic hiatus of 350 km between it and A. kraensis from Ranong Province, Thailand. Ansonia karensp. nov. is the newest member of a long list of range-restricted endemics having been recently discovered in the northern Tenasserim Mountain region of western Thailand and continues to underscore the unexplored nature of this region and its need for conservation.

A New Species

AbstractAmong fish parasitic nematodesRhabdochonais one of the most speciose genera, withc.100 species. Twelve congeneric species occur in Mexican freshwater fishes, in a region located between the Nearctic and Neotropical biogeographical regions. Host association and biogeographical history have determined the high species richness ofRhabdochonain Mexico. One of these species,Rhabdochona mexicana, is highly specific to the characid genusAstyanax.Characids are a group of freshwater fish with Neotropical affinity. In this paper, we explore the genetic diversity ofR. mexicanathrough samples obtained from populations ofAstyanaxspp. across river basins of Mexico and Guatemala. Sequences of one mitochondrial and two ribosomal genes were obtained from 38 individuals and analysed using Maximum Likelihood and Bayesian Inference analysis. Phylogenetic analyses usingcox1, and a concatenated alignment of 18S + 28S +cox1 recovered two genetic lineages. One of them corresponded withR. mexicana sensu stricto; this lineage included three reciprocally monophyletic subgroups; the other lineage was highly divergent and represented a putative candidate species. A detailed morphological study was conducted to corroborate the molecular findings. We describe a new species herein and discuss the implications of using molecular tools to increase our knowledge about the diversity of a speciose genus such asRhabdochona.

Age Estimates

A new species of lacertid lizard of the genus Psammodromus is described from the Iberian Peninsula. Genetic and recentlypublished phenotypic data support the differentiation of Psammodromus hispanicus into three, and not as previously sug-gested two, distinct lineages. Age estimates, lineage allopatry, the lack of mitochondrial and nuclear haplotype sharingbetween lineages, ecological niche divergence, and the current biogeographic distribution, indicated that the three lineagescorrespond to three independent species. Here, we describe a new species, Psammodromus occidentalis sp. n., which isgenetically different from the other sand racers and differentiated by the number of femoral pores, number of throat scales,snout shape, head ratio, green nuptial coloration, and number of supralabial scales below the subocular scale. We also pro-pose to upgrade the two previously recognized subspecies, Psammodromus hispanicus hispanicus Fitzinger, 1826 fromcentral Spain and Psammodromus hispanicus edwardsianus (Dugès, 1829) from eastern Spain, to the species level: Psam-modromus hispanicus stat. nov. and Psammodromus edwardsianus stat. nov. Given that the holotype of Psammodromushispanicus was lost, we designate a neotype. We also analysed museum specimens of P. blanci, P. microdactylus and P. algirus to describe differentiation of the Psammodromus hispanicus lineages/species from their closest relatives.

A New Species

A new species of the genus Colias Fabricius from the Arequipa region of Peru, C. misti Kir’yanov sp. nov., stat. nov., is established by raising it from the subspecies rank, C. lesbia misti Kir’yanov 2017. This taxonomic act is justified after detailed comparison of C. misti with representatives of phenotypically similar other South American Colias, including the subspecies of C. lesbia. The newly presented taxa are diagnosed by adult morphology, bionomics, and male genitalia. The diagnosis of a new subspecies Colias misti ccota Kir’yanov ssp. nov., discovered in the World’s deepest canyon Cotahuasi (Peru), is based on different and stable characters in phenotypes, genitalia, and bionomics of C. misti ccota and C. misti misti. Both subspecies of C. misti are endemic to the Western slopes of the Andes. It is also demonstrated that the shape of the male aedeagus is diagnostic for a reliable identification of the South American Colias.

A New Species

Halichoeres sazimai, n. sp. is described from the Western South Atlantic. During many years it was misidentified as H. bathyphilus from the Northwestern Atlantic, but it can be distinguished from the latter by striking color differences between the two species, with H. sazimai being characterized by a white body with a midline, zigzag patterned stripe on body, black and brownish in terminal males and yellow or golden in females and juveniles. Preserved specimens can also be distinguished by the visible mid-body stripe in H. sazimai, which disappears in H. bathyphilus. Diagnostic differences in the mitochondrial DNA cytochrome b gene separate H. sazimai from all other Western Atlantic labrids, with H. bathyphilus being its sister species. Individuals of H. sazimai were observed living on the deeper parts (20-40 m) of rocky reefs and sand bottoms, apparently associated with water temperatures lower than 18°C. This species is currently known from the southeastern and southern coasts of Brazil, from Espírito Santo to Santa Catarina States.

A new species of water mites from Montenegro and Bulgaria, Atractides anae Pešić sp. nov., is described, combining traditional morphological techniques with the analysis of partial mtDNA COI sequences (DNA-barcodes). Based on our molecular and morphological analysis, the new species is most closely related to the crenobiontic A. pennatus (K. Viets 1920) from which it differs by 6.4 (SD = 1.12)% K2P distance. A dataset including the novel COI sequences of 10 Atractides species from Montenegro and Iran is assembled in order to facilitate further studies on the genus by using molecular tools.

This is the second species known for the genus, which is restricted to the montane rainforests of north-eastern Madagascar. Dolurgocleptes is transferred from the tribe Dryocoetini to Polygraphini and placed near Polygraphus Erichson, based on examination of internal and external morphological characters and molecular data from Elongation Factor-1α and Cytochrome Oxidase I.

A New Species

A new species of Labuanium Serène & Soh, 1970, L. vitatum is described from northeastern Indian Ocean. It belongs to the L. rotundatum species-group, but is most closely related to L. scandens Ng & Liu, 2003, and L. papuomalesiacum (Nobili, 1899), the latter being here formally removed from synonymy with L. rotundatum (Hess, 1865) and raised to full species status. The new species differs from congeners by numerous characters including the structure of the male first pleopod, carapace and third maxillipeds, and by differences in proportions of the male abdominal somites.
