The Kokshaal racerunner, Eremchenko et Panfilov, 1999, together with other central Asian racerunner species, is included in the complex. In the present work, for the first time, the results of the analysis of historical mitochondrial DNA (barcode) are presented and the taxonomic status and preliminary phylogenetic relationships within the complex are specified. We present, for the first time, the results of the molecular analysis using historical DNA recovered from specimens of several species of this complex (paratypes of the Kokshaal racerunner and historical collections of the Kashgar racerunner from Kashgaria) using DNA barcoding.

In this study, we employed current methods of molecular phylogenetics based on 15 nuclear genes and the mitochondrial gene cytb to revise relations and systematics within Allactaginae. We also applied species distribution modelling projected on paleo-environmental data to reconstruct the geographic patterns of speciation in Allactaginae.

We examined the genetic variation in based on historical DNA samples from museum collections, including the type series. Mitochondrial and nuclear data indicated that the species complex includes two major clades: Northern (N) and Southern (S) ( distance 13%).

View Article and Find Full Text PDFFrogs of the genus include some of the world's smallest amphibians and represent the largest radiation of Asian microhylids, currently encompassing 50 species, distributed across the Oriental biogeographic region. The genus remains one of the taxonomically most challenging groups of Asian frogs and was found to be paraphyletic with respect to large-sized fossorial . In this study we present a time-calibrated phylogeny for frogs in the genus , and discuss taxonomy, historical biogeography, and morphological evolution of these frogs.

Researchers have previously placed the Malayan noctule, , into , because of similar body shape and proportions, or into , based on karyological analysis. This study reassesses using available collection material and compares it to various members of and , as well as with some other related and similar genera, based on respective morphological and molecular genetic features.

The mitochondrial analysis demonstrated that the type specimen of is close to several recently collected specimens from southern Gansu, northern Sichuan and Shaanxi, which are highly distinct from the two species of Asiatic short-tailed shrews of southern Sichuan, Yunnan, and Vietnam, and . Our analysis of four nuclear genes supported the placement of as sister to / , with the level of divergence between these two clades corresponding to that among genera of Soricinae.

Both molecular (28S rRNA) and morphological data support the position of this extraordinary eye-less genus within the family Scolopendridae Leach, 1814, a sighted clade, and thus suggests the polyphyly of blind scolopendromorphs. The species diagnosis has been amended and color images of provided for the first time.

Based on the morphological differences and high divergence in COI (mtDNA) gene sequences a new subspecies of is described from Khorasan Razavi Province in Iran. Partial sequences of COI mtDNA gene of 31 specimens of from 17 localities from all major parts of species range were analyzed.

As a key element of Palearctic deserts, it serves as a promising model for studies of historical biogeography and formation of arid habitats in Eurasia.
