Diagnosis: The species is distinguished from congeners by the densely grey or yellow pruinose sct with two narrow median apruinose stripes and two lateral apruinose stripes, the apruinose proximal half of abdominal T2, and features of the ơ terminalia (d aed shea laterally flattened).

Type material - The type specimens have to be considered lost. I was unable to locate the depository. Type locality and distribution ( Fig. 16 ): Sudan , Elba, Gebel, 2110'N 36 35'E . Efflatoun stated the type locality to be Gebel Elba in the south-eastern desert in Egypt . The only place I was able to find is Elba in north-eastern Sudan , lying close to the border of present day Egypt . Additionally to the specimens examined, the species is known to occur in Sudan in the Afrotropical Region (Oldroyd 1980) and Egypt in the Palaearctic Region ( Lehr 1988 ) .
