Cymbium with retrolateral swelling and prolateral row of five comb-shaped setae. Embolus a broad semi-circular sclerite, truncate and indented at its tip, with subdistal tooth near sperm duct opening. Tegulum with swelling in centre. MA with narrow, strongly sclerotized prong, pointing retrolaterad.

Female. Described in Jocqué (2011).

Remark. The species was described from a female allegedly from a locality in the United Arabian Emirates ( UAE). The specimen had been registered with a collection of A. van Harten from the UAE that was submitted with labels that only mentioned a number referring to an Excel-sheet with all the details. One tube mentioned CV105 and was given a label with the data corresponding to the field number ‘105’. In a collection of the same collector from Cape Verde that was acquired later, a conspecific female and the corresponding males (here described) were found in a tube with label CV15. It is thus clear that the species is from Cape Verde and should have been registered with the data corresponding to ‘CV105’. Therefore, the type locality is Cape Verde, Santiago São Jorge dos Órgãos.
