Cheumatopsyche parafra Oláh & Johanson , new species

Fig. 183–186

The genitalic structures follow the general pattern of C. afra Mosely. The species is morphologically similar to C. chirapali , new species from which it is distinguished in forewings by the homogenous brown membrane. In addition, segment IX is longer, the apices of the apicoventral setal lobes turn only slightly mesad; the distal ends of the coxopodites are less dilated; the phallotheca is not constricted at mid-length, and the sclerotised endothecal lobes are prolonged posterad.

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. Each protibiae with 2 spurs. Forewing length 7.4 mm, hind wing length 5.6 mm. Forewing crossveins m-cu and cu tangental. Hind wing fork I absent.

Male genitalia. Segment IX fused annularly, short ( Fig. 183); tergum half as long as sternum ( Fig. 183); anterior margins of segment IX regularly convex in lateral view; tergal parts less excising, flatter than sternal parts; apical lobe on posterolateral margins of segment IX broad, triangular, short, located above base of coxopodites, located at mid-height of segment ( Fig. 183); spine row along posterior margin of segment IX continuous. Intersegmental step between segment IX and segment X sloping. Segment X long, with apicoventral lobe subtriangular in lateral view ( Fig. 183); nearly quadrangular in dorsal view ( Fig. 184); widely separate in dorsal view ( Fig. 184). Transverse sutures located centrally on segment X; running toward both lateral setose areas. Longitudinal sutures not visible. Setaless mesocaudal lobe with slightly convex central margin ( Fig. 184). Apicoventral setal lobes straight, with slightly tapering, posterodorsad orienting apices ( Fig. 183); in dorsal view slightly curving mesad ( Fig. 184). Pair of lateral setose areas forming small, elevated setose surfaces, located immediately below posterior end of transverse sutures, above base of apicoventral setal lobes ( Fig. 183). Coxopodites extending beyond apex of segment X, curving ventrad along their length, apically dilated ( Fig. 183). Harpagones slender, slightly curving dorsad in lateral view; finger-like except with broad base in lateral view ( Fig. 183); nearly straight in ventral view ( Fig. 185). Phallotheca ( Fig. 186) sinuate, not constricted at mid-length; sclerotised endothecal process elongate, narrow; phallotremal sclerites visible in ventrocaudal corner ( Fig. 186).

Holotype male: MADAGASCAR: Perinet , xii.1954 [R. Paulian] ( MNHN, in alcohol).

Paratypes: MADAGASCAR: Perinet , xi–xii.1954 (R. Paulian) — 6 males ( MNHN, in alcohol), 2 males ( OPC, in alcohol) .

Distribution: Madagascar.

Etymology: referring to its general similarity to C. afra Mosely , widely distributed in the mainland Africa.
