Baryphas scintillans Berland & Millot 1941

Baryphas scintillans Berland & Millot, 1941 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. Material examined UGANDA • 1 ♂, 2 ♀♀; Entebbe; Apr. 2001; FSCA • 1 ♂, 1 ♀; Entebbe, Botanical Gardens; on vegetation; 2 Apr. 1995; D.
