Abstract Since early in its taxonomic history, placement of the Socorro Wren (Thryomanes sissonii) has been an object of contention. Of particular interest is its current placement in the genus Thryomanes, which makes that genus ditypic and leads to an odd biogeographic scenario for the Socorro Wren's colonization of Socorro Island. We assessed its phylogenetic position by analyzing 516 base pairs of mitochondrial DNA sequences from the ND2 gene of this species and 14 additional wren taxa. Contrary to its present placement, the Socorro Wren is nested phylogenetically within the House Wren species complex, being placed as sister to the clade Troglodytes aedon + T. musculus. The current hypothesis (i.e. sister to Thryomanes bewickii) is strongly invalidated by our analysis. Our analyses indicate that the most appropriate taxonomic classification for the Socorro Wren is Troglodytes sissonii. Posición Filogenética y Ubicación Genérica de Thryomanes sissonii

A New Species

A new species of the genus Caecilia (Caeciliidae) from the western foothills of the Serranía de los Yariguíes in Colombia is described. Caecilia pulchraserranasp. nov. is similar to C. degenerata and C. corpulenta but differs from these species in having fewer primary annular grooves and a shorter body length. With this new species, the currently recognized species in the genus are increased to 35. Mitochondrial DNA sequences, including newly sequenced terminals representing two additional, previously unanalyzed species, corroborate the phylogenetic position of the new species within Caecilia and the monophyly of the genus. This analysis also included newly sequenced terminals of Epicrionops aff. parkeri (Rhinatrematidae) and trans-Andean Microcaecilia nicefori (Siphonopidae). Evidence was found for the non-monophyly of the family Siphonopidae and the siphonopid genera Microcaecilia and Siphonops. The implications of these results for caecilian systematics are discussed and the status of the trans-Andean populations of Caecilia degenerata is commented upon.

Background: Genome-scale approaches have played a significant role in the analysis of evolutionary relationships. Because of rich polymorphisms, high evolutionary rate and rare recombination, mitochondrial DNA sequences are commonly considered as effective markers for estimating population genetics, evolutionary and phylogenetic relationships. Flying fishes are important components of epipelagic ecosystems. Up to now, only few complete mitochondrial genomes of flying fishes have been reported. In the present study, the complete mitochondrial DNA sequences of the Cheilopogon pinnatibarbatus japonicus and Hirundichthys rondeletii had been determined. Methods: Based on the published mitogenome of Cheilopogon atrisignis (GenBank: KU360729), fifteen pairs of primers were designed by the software Primer Premier 5.0 to get the complete mitochondrial genomes of two flying fishes. According to the reported data, the phylogenetic position of two flying fishes were detected using the conserved 12 protein-coding genes. Result: The complete mitochondrial genomes of Cheilopogon pinnatibarbatus japonicus and Hirundichthys rondeletii are determined. They are 16532bp and 16525bp in length, respectively. And they both consists of 13 protein-coding genes, 22 transfer RNA (tRNA) genes, two ribosomal RNA (rRNA) genes and a control region. The OL regions are conserved in these two flying fishes and might have no function. From the tree topologies, we found C.p. japonicus and H. rondeletii clustered in a group. The findings of the study would contribute to the phylogenetic classification and the genetic conservation management of C.p. japonicus and H. rondeletii.

Meadow vipers (Vipera ursinii–renardi complex) are small-bodied snakes that live in either lowland grasslands or montane subalpine-alpine meadows spanning a distribution from France to western China. This complex has previously been the focus of several taxonomic studies which were based mainly on morphological, allozyme or immunological characters and did not clearly resolve the relationships between the various taxa. Recent mitochondrial DNA analyses found unexpected relationships within the complex which had taxonomical consequences for the detected lineages. The most surprising was the basal phylogenetic position of Vipera ursinii graeca, a taxon described almost 30 years ago from the mountains of Greece. We present here new analyses of three nuclear markers (BDNF, NT3, PRLR; a first for studies of meadow and steppe vipers) as well as analyses of newly obtained mitochondrial DNA sequences (CYT B, ND4).Our Bayesian analyses of nuclear sequences are concordant with previous studies of mitochondrial DNA, in that the phylogenetic position of the graeca clade is a clearly distinguished and distinct lineage separated from all other taxa in the complex. These phylogenetic results are also supported by a distinct morphology, ecology and isolated distribution of this unique taxon. Based on several data sets and an integrative species concept we recommend to elevate this taxon to species level: Vipera graeca Nilson & Andrén, 1988 stat. nov.
