Peptidomic analysis of skin secretions from Rana heckscheri and Rana okaloosae provides insight into phylogenetic relationships among frogs of the Aquarana species group

Mitochondrial DNA (mtDNA) restriction site maps for three Drosophila montium subgroup species of the melanogaster species group, inhabiting Indian and Afrotropical montium subgroup territories, were established. Taking into account previous mtDNA data concerning six oriental montium species, a phylogeny was established using distance-matrix and parsimony methods. Both genetic diversity and mtDNA size variations were found to be very narrow, suggesting close phylogenetic relationships among all montium species studied. The phylogenetic trees that were constructed revealed three main lineages for the montium subgroup species studied: one consisting of the Afrotropical species Drosophila seguyi, which is placed distantly from the other species, one comprising the north-oriental (Palearctic) species, and one comprising the southwestern (south-oriental, Australasian, Indian, and Afrotropical) species. The combination of the mtDNA data presented here with data from other species belonging to the melanogaster and obscura subgroups revealed two major clusters: melanogaster and obscura. The melanogaster cluster is further divided into two compact lineages, comprising the montium subgroup species and the melanogaster complex species; the species of the other complex of the melanogaster subgroup, yakuba, disperse among the obscura species. The above grouping is in agreement with the mtDNA size variations of the species. Overall, among all subgroups studied, the species of the montium subgroup seem to be the most closely related. Key words : mtDNA restriction site maps, mtDNA size variations, Drosophila, phylogeny.

Abstract The combination of genetic and phenotypic characters for species delimitation has allowed the discovery of many undescribed species of Neotropical amphibians. In this study, we used DNA sequences (genes 12S, 16S, ND1 and COI) and morphologic, bioacoustic and environmental characters of the Boana semilineata group to evaluate their phylogenetic relationships and assess their species limits. In addition, we included DNA sequences of several species of Boana to explore cryptic diversity in other groups. We found three Confirmed Candidate Species (CCS) within the B. semilineata group. Holotype examination of Hyla appendiculata shows that it is a valid species that corresponds to one of the CCS, which is here transferred to Boana. We describe the two remaining CCS. Our phylogeny highlights a number of secondary but meaningful observations that deserve further investigation: (1) populations of B. pellucens from northern Ecuador are more closely related to B. rufitela from Panama than to other Ecuadorian populations of B. pellucens; (2) we report, for the first time, the phylogenetic relationships of B. rubracyla showing that it is closely related to B. rufitela and B. pellucens; and (3) B. cinerascens and B. punctata form two species complexes consisting of several unnamed highly divergent lineages. Each of these lineages likely represents an undescribed species.

Close Phylogenetic Relationship

We examined phylogenetic relationships among newst of the genus Paramesotriton using partial mitochondrial gene se-quences, including the ND2-tRNATyr region (1415 bp) and the 12S rDNA-tRNAVal -16S rDNA region (1774 bp), from 42individuals of 10 recognized Paramesotriton species and outgroups by Bayesian inference (BI), Maximum likelihood(ML) and Maximum Parsimony (MP) methods. We found that, (1) Laotriton laoensis is the sister group of Paramesotri-ton, (2) the genus Paramesotriton is monophyletic, composed of either the P. caudopunctatus species group and the P.chinensis species group, or the subgenera Allomesotriton and Paramesotriton (3) P. longliensis and P. zhijinensis shouldbe placed in the P. caudopunctatus species group or subgenus Allomesotriton; (4) P. fuzhongensis is not a junior synonym of P. chinensis, and there is a close phylogenetic relationship between P. fuzhongensis and P. guangxiensis.

Limited Dispersal

A small sector of Northern Apennines the Tuscan-Emilian Apennines constitutes an interesting diversity centre of a new Verdanus species group closely related to V. bensoni and the V. limbatellus group. It consists of three species: V. tyrannus sp. nov., V. saurosus sp. nov. and V. rosaurus sp. nov., the latter with two subspecies, V. rosaurus rosaurus ssp. nov. and V. rosaurus rex ssp. nov., which doubtless form a monophyletic group (V. rosaurus group). Data on their distribution, ecology and life cycle are added to their original descriptions. The new taxa live allopatrically in a very restricted area and thus occupy a distribution gap of another species group of Verdanus, the V. abdominalis group, present in Italy in the mountain regions of the Alps and Central and Southern Apennines. A hypothesis of the origin of the new taxa is presented based on the ecological conditions in the Tuscan-Emilian Apennines during the last Postglacial period and on the limited dispersal ability of these normally brachypterous insects. Possible synapomorphic characters and phylogenetic relationships of the new taxa with each other and with V. bensoni (China) and the V. limbatellus group (V. limbatellus (Zetterstedt), V. kyrilli (Emeljanov), V. sichotanus (Anufriev), V. kaszabi (Dlabola)) are discussed and a cladistic analysis is conducted. Comparing V. bensoni and the V. limbatellus group on the one hand and the V. rosaurus group on the other, some morphological characters appear to change often in parallel on the same paths, independently from the phylogenetic hypothesis. Remarkably, within the same morphological characters the range of variation among species inhabiting the comparatively minute area of the Tuscan-Emilian Apennines is similar to that found among other taxa distributed across vast areas of northern and central Eurasia.

Recently, in an examination of the phylogenetic relationships among the mole-rats of the family Bathyergidae (Mammalia: Rodentia), Ingram et al. (2004) documented molecular evidence for the recognition of the Cryptomys mechowii species group at the generic level and resurrected the name Coetomys Gray, 1864 for this group. Subsequent literature review revealed that Coetomys is not available to this species group, being a junior synonym of Cryptomys Gray, 1864. Here, we describe and diagnose Fukomys genus novum. In addition, we discuss the taxonomic history of this group in an attempt to reduce the nomenclatural confusion that has plagued studies of the Bathyergidae for over a century.
