Diagnosis

This species is related to Icius grassei ( Berland & Millot, 1941) . Both species are very similar in size, shape of body and colouration. The male can be recognized by the palpal tibial apophysis, which is pointed in I. grassei but wide and truncate at the tip in the newly described species, (compare Fig. 28B with Wesołowska 2017: fig. 1c). The female of both species have an epigyne with a centrally placed atrium, but the internal structures of the epigyne are different (compare Fig. 28D with Wesołowska 2017: fig. 2d). Icius grassei has a large pocket located at the epigastric fold (no pocket in I. bandama sp. nov.).

Etymology

The specific name is a noun in apposition, referring to the type locality.
