Derelomus rhodesianus Hesse, 1929: 529.

Differential diagnosis

This species is distinct from all Ebenacobius by the presence of small whitish scales on prothorax and elytra ( Fig. 1I View Fig ). It is closest in general appearance to E. turneri gen. et comb. nov. but the latter species has appendiculate claws (claws simple in E. rhodesianus gen. et comb. nov.).

Remarks

The single card mounted specimen used by Hesse (1929) for the description of Derelomus rhodesianus Hesse was located in the collection housed at SAMC. This specimen bears a red type label, it was identified as the holotype for this species and labelled accordingly.

Life history

This species was collected in large numbers on Euclea cf. crispa . Adults were observed on the branches, near the flower buds before blooming. The single record on flowers of Lonchocarpus ( Fabaceae ) is probably accidental. Adults were collected from July to October.
