Cheumatopsyche rineta Oláh & Johanson , new species

Fig. 187–190

This species is similar to C. afra Mosely in the genitalia. It is very close to C. chirapali new species, distinguished by its homogenously brown forewing membranes. In addition, segment X is shorter; the apices of the apicoventral lobes are thicker and only slightly turned mesad. Furthermore, the apex of both coxopodites are more dilated; the phallotheca is not constricted at mid-length, and the sclerotised endothecal lobes are short.

Male. Body and wing membrane brown with light pubescence. Maxillary palp segment I shortest, segment II longer, segments III and IV equally long, segment V as long as sum of segments I–IV. Head dorsum brown, with 5 warts of same dark colour. Proepisternum without swollen setal wart. Protarsal claws asymmetrical, laterally flanked by setal bundle. Protibiae each with 2 spurs. Forewing length 6.7 mm, hind wing length 5.3 mm. Forewing crossveins m-cu and cu tangental. Hind wing fork I absent.

Male genitalia. Segment IX fused annularly, short; tergum half as long as sternum ( Fig. 187); tergum capitate in lateral view ( Fig. 187); anterior margins of segment IX regularly convex in lateral view ( Fig. 187), tergal part less excised, flatter than sternal part ( Fig. 187); apical lobe on posterolateral margins broadly triangular, located above base of coxopodites; spine row along posterior margins of segment IX continuous. Intersegmental area between segment IX and segment X stepped. Segment X short, with apicoventral setal lobes slightly narrowing and curving dorsad in lateral view ( Fig. 187); lobes nearly quadrangular and narrowly separated in dorsal view ( Fig. 188). Transverse sutures located centrally on segment X, running immediately above lateral setose areas ( Fig. 187). Longitudinal sutures not visible. Setaless mesocaudal lobe forming plate with centrally convex margin ( Fig. 188). Pair of lateral setose areas forming setose surfaces located behind and below end of transverse sutures, immediately above apicoventral setal lobes. Coxopodites exceeding apex of segment X; straight, with strongly dilating apex. Harpagones slender, curving dorsally and finger-like in lateral view ( Fig. 187), in ventral view continuing from bulbous coxopodite apices ( Fig. 189). Phallothecal dorsum ( Fig. 190) straight, not constricted at midlength; sclerotised endothecal process short; phallotremal sclerites visible as horizontal small plates.
