A preliminary molecular phylogeny of the Namib Desert darkling beetles (Tenebrionidae)
A systematic classification of Namib Desert darkling beetles (Coleoptera: Tenebrionidae) based on morphological characters is complicated as strong selection pressures exerted by desert conditions have led to a suite of convergent morphological characteristics. Here we present a first and preliminar...
