Diagnosis

This species shares the shape of the copulatory canals with Rhene formosa Rollard & Wesołowska, 2002 , they are long, very thin and situated mesially; however, the two species differ in sclerotization of atria – cf. Fig. 79C with Rollard & Wesołowska (2002: fig. 16c).

Etymology

Specific epithet is Latin, meaning ‘sisterly’ (noun in genitive), and refers to kinship of this species to other members of Rhene .
