Hyllus lwoffi Berland & Millot, 1941: 337 , fig. 41.

Diagnosis

The female of this species can be distinguished from congeners by the abdominal pattern with four pairs of white dots in the posterior part and by the structure of the epigyne with two lateral pockets with heavily sclerotized rims located at the epigastic furrow ( Fig. 21B ). The epigyne appears to have two small holes at the posterior border.
