Triturus anatolicus
http://novataxa.blogspot.com/2016/05/tr ... licus.html

Multilocus molecular data play a pivotal role in diagnosing cryptic species (i.e. genetically distinct but morphologically similar species). A multilocus phylogeographic survey has provided compelling evidence that Triturus ivanbureschi sensu lato comprises two distinct gene pools with restricted gene flow. We conclude that this taxon had better be treated as two distinct (albeit morphologically cryptic) species. The name T. ivanbureschi should be restricted to the western species, which is distributed in western Asiatic Turkey plus the south-eastern Balkan Peninsula. No name is as yet available for the eastern species, which is distributed in northern Asiatic Turkey. We propose the name Triturus anatolicus sp. nov. for the eastern species and provide a formal species description.



Pachytriton wuguanfui
http://novataxa.blogspot.com/2016/03/pa ... anfui.html

Despite recent descriptions of multiple new species of the genus Pachytriton (Salamandridae), species richness in this China-endemic newts genus likely remains underestimated. In this study, we describe a new species of Pachytriton from northeastern Guangxi and southern Hunan, southeastern China. Both molecular analyses and morphological characters reveal that the new species can be distinguished from its congeners. The mitochondrial gene tree identified the new lineage highly divergent (uncorrected p-distance > 5.8 % by mitochondrial gene) from currently recognized species and placed it as the sister species of P. xanthospilos and P. changi. Furthermore, a nuclear gene haplotype network revealed a unique haplotype in the new populations. Statistical species delimitation using Bayes factor strongly supported the evolutionary independence of the new species from the closely-related P. xanthospilos. Morphologically, the new species is characterized by a uniformly dark brown dorsum without bright orange dots or black spots; irregular orange blotches on the venter; tips of fingers and toes orange on the dorsal side; moderately developed webs on the side of digits; absence of costal grooves between the axilla and groin; and widely open vomerine tooth series.

not new species, but new genera for some of the former Mabuya, Trachylepis. For the "mediterranean" countries:
Karin et al., 2016 split the circumtropical Mabuya group. For the area, covered here by this database,
Trachylepis vittata
Trachylepis aurata
Trachylepis septemtaeniata

are now in the masculin genus Heremites GRAY, 1845

Heremites vittatus
Heremites auratus
Heremites septemtaeniatus

Regarding "threat", please consult the English dictionary... or you really meant it?

Oedipina capitalina • On the Taxonomy of Oedipina stuarti (Caudata: Plethodontidae), with Description of A New Species from Suburban Tegucigalpa, Honduras

Abstract: We review the taxonomy and distribution of Oedipina stuarti in Honduras. Based on uncertainty related to the type locality, we restrict the taxon to the holotype, which we posit originated from a mine in the northern portion of the Department of Valle, Honduras. We subsequently describe a new species of Oedipina from Distrito Central, Departamento de Francisco Morazán, Honduras, based on newly collected material as well as one specimen previously designated as a paratype of O. stuarti. The new species is differentiated from all other members of the genus by having 19 costal grooves, 20 trunk vertebrae, 27–38 maxillary teeth, and 20–24 vomerine teeth, as well as by its phylogenetic relationships. Phylogenetic analysis suggests this species to be most closely related to O. ignea, O. motaguae, and O. stenopodia, three other members of the subgenus Oedipina known to inhabit dry deciduous forest habitats in Guatemala and Honduras.

Key words: Amphibia, subgenus Oedipina, Oedipina sp. n., Francisco Morazán, Honduras, morphology.

Distribution and natural history: O. capitalina sp. n. is known only from type locality, a suburban homestead yard adjacent to a heavily degraded headwater stream near the top of Cerro Grande in the central portion of the Departamento de Francisco Morazán (Fig. 7). This locality lies in the upper portion of the Choluteca Valley on the northern side of Tegucigalpa at 1,220 m a.s.l.. This denuded area lies within the Premontane Dry Forest formation (Holdridge 1967, Townsend & Wilson 2010) and likely supported both dry forest and pine-oak forest habitat prior to its being denuded. Specimens were collected during the day in June and September from underneath rotten logs and dead vegetation.

Etymology: The specific name “capitalina” is a Honduran colloquialism that refers to a female inhabitant of the capital city of Tegucigalpa. This name is given in reference to the type locality’s proximity to the largest city in the country and is used as a noun in apposition.

[Herpetology • 2016] Hynobius unisacculus • A New Species of Salamander of the Genus Hynobius (Caudata, Hynobiidae) from South Korea

Image


Abstract

We describe a new species of lentic-breeding Hynobius salamander from the Naro Islands, near the village of Bongrae-myeon, Goheung-gun, Jeollanam-do, South Korea, on the basis of results of morphological, ecological and genetic analyses. Hynobius unisacculus sp. nov. is distinguished from its congeners by a combination of the following morphological attributes: (1) comparatively small size (adult SVL up to 61 mm; range 38.3–60.3 mm in males and 37.5–59.9 mm in females); (2) relatively slender short limbs; tips of fore- and hindlimbs adpressed on body never meeting, but separated by a large gap (gap of -3.0 to -1.5 costal folds in males and -3.5 to -1.5 in females); (3) comparatively short tail (TL/SVL ratio in adult males varying from 0.54–0.98, in adult females from 0.55 to 0.89), tail flattened and with a low dorsal fin extending to the posterior one-third of tail length; (4) usually 11 (occasionally 12) costal grooves; (5) in adults, dark brown dorsum with indistinct bronze or dark copper spots, lighter greyish-white or pinkish belly; (6) well developed fifth toe; (7) comparatively shallow vomerine tooth series with 13–23 vomerine teeth; (8) small, pigmented ova, located in one, occasionally two, strings in a small, curved egg sac with folded envelope, lacking distinct mucous stalks or whiptail-like structures on both ends. The molecular differentiation among Korean Hynobius is high; Hynobius unisacculus sp. nov. is genetically highly divergent from the morphologically similar H. leechii, H. yangi and H. quelpaertensis: pairwise distances are 9.7%, 9.1% and 8.0% of sequence divergence at the COI mtDNA gene respectively, and 10.9%, 10.9% and 9.4% of sequence divergence at the cyt b mtDNA gene, respectively. At present, the new species is known from coastal areas and offshore islands in southeastern part of Jeollanam-do in South Korea. We suggest the species should be considered as Vulnerable (Vu2a) in accordance with IUCN’s Red List categories. Our study supports the presence of undiagnosed taxonomic diversity among Korean Hynobius.

Keywords: Amphibia, Hynobius unisacculus sp. nov., H. leechii, H. quelpaertensis, H. yangi, egg sacs, lentic-breeding species, mtDNA, morphology

Not really new, but may you didn't noticed, even though we already spammed the entire facebook. :D
