Derelomus baka Haran sp. nov. urn:lsid:zoobank.org:act: 288FC910-5687-42E8-A423-8C0643C74AC7 Fig. 27 Diagnosis In the D. ephippiger group, this species can be distinguished by the combination of a rostrum distinctly longer than the pronotum in lateral view, the concolorous club and the elytra with a single dark spot near the middle of the suture. This species is close to D. antonioui, but in the latter species, the protibiae lack a comb of erect setae in the male and the body of the penis is more elongate. Etymology The species is dedicated to the Baka people, semi-nomadic hunter-gatherers of central Africa, including Cameroon. These people live in a remarkable and non-destructive equilibrium with forest ecosystems enabling the maintaining of the high biodiversity of these biomes.
