Description | Onymacris brainei Penrith, 1984 – the most recent species of Onymacris to be described – is known only
from its type locality in the Namib Desert, adjacent to the Cunene River in northern Namibia. No additional
specimens are known to have been collected beyond the type series. Herein, we report on eight specimens
discovered at a second site near the original locality. DNA from four beetles was used to determine
the phylogenetic placement of O. brainei among congeners, based on sequence data from one nuclear
(histone III) and two mitochondrial (cox1, cox2) genes. Maximum likelihood analysis identifies O. brainei
as a member of the ‘white’ Onymacris clade, in which it forms a strongly supported subclade with O. bicolor
and O. marginipennis. More broadly, its phylogenetic placement augments previous molecular results
that revealed a sister taxon relationship between the ‘white’ Onymacris and a second genus, Physadesmia.
The paraphyly of Onymacris with respect to Physadesmia highlights a need for nomenclatural change, but revision should await acquisition of genetic data for the few species outstanding in both genera. | en_US |
