An investigation of name-bearing types and other relevant type specimens of twelve nominal Leptopelis taxa described from or distributed in the Eastern Arc Mountains in East Africa was carried out. Our aim was to clarify their status and where necessary revise respective nomina. We suggest several nomenclatural and taxonomic actions: 1) Leptopelis barbouri Ahl, 1929 is transferred to the synonymy of Leptopelis flavomaculatus (Günther, 1864) as a junior subjective synonym; 2) Leptopelis grandiceps Ahl, 1929 is resurrected from the synonymy of Leptopelis uluguruensis Barbour & Loveridge, 1928 as a valid species conforming to the tree frogs which have been known as 'L. barbouri' and a lectotype is designated; 3) Leptopelis usambarae Ahl, 1929 is transferred from the synonymy of L. uluguruensis Barbour & Loveridge, 1928 to the synonymy of L. grandiceps Ahl, 1929 as a subjective synonym; 4) a lectotype of Leptopelis amaniensis Ahl, 1929 (synonym of L. uluguruensis), Hylambates johnstoni Boulenger, 1897 (synonym of L. flavomaculatus) and Leptopelis signifer Ahl, 1929 (synonym of L. vermiculatus) is designated to stabilize identity of the nomina; and 5) the type locality of Leptopelis martiensseni Ahl, 1929 and Leptopelis tanganus Ahl, 1929 is corrected. © 2014 Magnolia Press.

Climate change can lead to decreased climatic suitability within species distributions, increased fragmentation of climatically suitable space, and/or emergence of newly suitable areas outside present distributions. Each of these extrinsic threats and opportunities potentially interacts with specific intrinsic traits of species, yet this specificity is seldom considered in risk assessments. We present an analytical framework for examining projections of climate change-induced threats and opportunities with reference to traits that are likely to mediate species responses, and illustrate the applicability of the framework.Sub-Saharan Africa.We applied the framework to 195 sub-Saharan African amphibians with both available bioclimatic envelope model projections for the mid-21st century and trait data. Excluded were 500 narrow-ranging species mainly from montane areas. For each of projected losses, increased fragmentation and gains of climate space, we selected potential response-mediating traits and examined the spatial overlap with vulnerability due to these traits. We examined the overlap for all species, and individually for groups of species with different combinations of threats and opportunities.In the Congo Basin and arid Southern Africa, projected losses for wide-ranging amphibians were compounded by sensitivity to climatic variation, and expected gains were precluded by poor dispersal ability. The spatial overlap between exposure and vulnerability was more pronounced for species projected to have their climate space contracting We illustrate the application of a framework combining spatial projections of climate change exposure with traits that are likely to mediate species responses. Although the proposed framework carries several assumptions that require further scrutiny, its application adds a degree of realism to familiar assessments that consider all species to be equally affected by climate change-induced threats and opportunities.

Data on an infestation of ectoparasites on a Canarian Houbara Bustard Chlamydotis undulata, fuerteventurae Rothschild et Hartert, 1894 are presented for the first time. Two insect groups were discovered: Icosta (Rhyponotum) pilosa (Macquart, 1843) (Hippoboscidae, Diptera) and a possibly unnamed species of Philopteridae (Phthiraptera) closely allied to Otidoecus houbarae (Barthélemy, 1836). For the latter, a DNA-barcode is presented. The philopterid was found in a phoretic relationship with the hippoboscid. © Fundacja Natura optima dux.

For the first time a comprehensive checklist and description of all species of the dwarf snake genus Eirenis is presented using both external morphological characters and osteological information derived from micro-computed tomography, and by considering more than 300 specimens from the entire distribution range. Our study recognizes 18 valid species, but also emphasizes that Eirenis modestus and E. persicus each represent a complex of several taxa which urgently need a revision. Regarding the latter complex, the validity of the taxon "Eirenis mcmahoni" is not accepted due to the current lack of understanding of the persicus-group. Also, further studies should be carried out to fully understand the species status of the newly described Eirenis kermanensis, which seems closely related to E. medus. At the same time, E. hakkariensis is resurrected to full species status given the dramatic morphological differences to E. thospitis, casting doubt on the apparent genetic identity as revealed by a previous investigation. In addition, our study presents the first record of E. eiselti for Syria. On the basis of our results it is for the first time possible to compile a key to all currently recognized species of Eirenis, which should be helpful for future systematic studies and faunal surveys. © Senckenberg Gesellschaft für Naturforschung, 2013.
