Derelomus incognitus Hesse, 1929: 526.

Differential diagnosis

This species can be distinguished by the following combination: claws appendiculate and dorsum (prothorax + elytra) with minute whitish setae, glabrous in appearance. In most specimens, the basal 4/5 of first interstriae are dark brown ( Fig. 3F View Fig ). Apex of protibiae in females has a long premucro giving the impression of a double mucro.

Remarks

Ebenacobius incognitus gen. et comb. nov. was described in the genus Derelomus based on a single male deposited at SAMC ( Hesse 1929). This specimen was loaned to Guillermo Kuschel (loan 24018) who undertook a study on palaeotropical Derelomini from 2007. Unfortunately he passed away before he could complete this work and left the very preliminary manuscript and the material borrowed from institutions (see postscript in Haran et al. 2020). Despite intensive search in the material of Derelomini loaned, the holotype of this species could not be identified and is provisionally considered as lost. This species is very distinct and specimens examined were easily identified based on Hesse’s description.

Life history

Host plant unknown. The record on Encephalartos longifolius (Jacq.) Lehm. is accidental given the known biology of the genus. Adults were collected in March, April, August, November and December.
