Figs 5–6

Baryphas scintillans Berland & Millot, 1941: 316 , fig. 18.

Diagnosis

The species is similar to Baryphas jullieni Simon, 1902 . The male can be recognized by the curved tibial apophysis of the palp vs straight in the latter species. The female colour pattern is the same as in B. jullieni . The epigynes of both species are similar, but differ in their internal structure; a characteristic feature of B. scintillans is the presence of two large posterior pockets, while B. jullieni has a strongly sclerotized rim.
