A New Species of Trechus from the Ethiopian Highlands (Coleoptera: Carabidae: Trechinae) and Key to the Trechus Species of Ethiopia

The enormous genus Trechus Clairville is distributed mainly in the Holarctic regions, but 24 species from Ethiopia were described previously. A key to the species of Ethiopian Trechus is provided, including a new species, Trechus amharicus from the Choke Mountains (Ethiopian Highlands). The latter taxon is described. The species was found in the Afroalpine grassland, living under stones, sometimes located at the base of the giant Lobelia rhynchopetalum Hemsl. It is noteworthy that in spite of the small number of known species of Ethiopian Trechus, there are more morphological and chaetotaxic variations among them than in their Holarctic congeners. The taxonomic position of the new species is difficult to situate, because T. amharicus does not fit in any of the groups of species recognized to date in Ethiopia. T. amharicus n. sp. bears some resemblance to T. patrizii in that it has a pronotum with posterior angles without setae, and elytra with only a single anterior discal seta. However, the different configuration of the protarsus and aedeagus in the male clearly separates the two taxaThis work was supported by the University of Santiago de Compostela (Spain).

Rare failures of DNA bar codes to separate morphologically distinct species in a biodiversity survey of Iberian leaf beetles

During a survey of genetic and species diversity patterns of leaf beetle (Coleoptera: Chrysomelidae) assemblages across the Iberian Peninsula we found a broad congruence between morphologically delimited species and variation in the cytochrome oxidase (cox1) gene. However, one species pair each in the genera Longitarsus Berthold and Pachybrachis Chevrolat was inseparable using molecular methods, whereas diagnostic morphological characters (including male or female genitalia) unequivocally separated the named species. Parsimony haplotype networks and maximum likelihood trees built from cox1 showed high genetic structure within each species pair, but no correlation with the morphological types and neither with geographic distributions. This contrasted with all analysed congeneric species, which were recovered as monophyletic. A limited number of specimens were sequenced for the nuclear 18S rRNA gene, which showed no or very limited variation within the species pair and no separation of morphological types. These results suggest that processes of lineage sorting for either group are lagging behind the clear morphological and presumably reproductive separation. In the Iberian chrysomelids, incongruence between DNA-based and morphological delimitations is a rare exception, but the discovery of these species pairs may be useful as an evolutionary model for studying the process of speciation in this ecological and geographical setting. In addition, the study of biodiversity patterns based on DNA requires an evolutionary understanding of these incongruences and their potential causes.AB was funded by the Spanish Ministry of Science and Innovation (grant CGL2009-10111).
