Diagnosis

The male of Andromma deogratias sp. nov. is characterized by the shape of the RTA with a fairly long, slender, sharp, tipped prong, pointing antero-dorsally. The female has an epigyne with egg shaped copulatory openings in a trapezoidal epigyne and long spermathecae hardly separated from the copulatory ducts.

Etymology

The species name is a patronym after Déogratias Nduwarugira, who collected all the available specimens.
