Diagnosis

The female of this species has an epigyne similar to that in Evarcha pinguis Wesołowska & Tomasiewicz, 2008 from Ethiopia. Both species have lateral pockets in the anterior part, also the internal structure of their epigynes are similar. They differ in the shape of the epigynal depressions, whereas E. pinguis has two large round depressions with strongly sclerotized lips the depressions in Evarcha zougoussi sp. nov. are only slightly marked (compare Fig. 16D with Wesołowska & Tomasiewicz 2008: fig. 61).
