Cheumatopsyche krugerana Oláh & Johanson , new species

Fig. 380–383

This species is similar to C. brazzana Oláh & Johanson from Zaïre from which it is easily distinguished by the presence of serrate harpagones and by the presence of circular, sclerotized endothecal process on the phallothecal apex.

Male. Body and wings pale stramineous, with light pubescence; legs and antennae stramineous. Maxillary palp formula I-II-(III, IV)-V, segment V as long as sum of segments I–IV. Head dorsum pale brown, with 7 pale brown setal warts. Swollen setal wart absent on proepisternum. Setal wart present on precoxale. Pretarsal claws asymmetrical, laterally flanked by setal bundle. Mid- and hind-leg claws asymmetrical. Spur fomula 244. Protibiae with posteroapical spur much smaller than anteroapical spur.

Wings. Forewing evenly pale, with slightly darker veins. Crossveins m-cu and cu situated closely, distance between them equal to length of crossvein m-cu. Sc and R, and Cu2 and A1 separate along their lengths. Hind wing Sc and R meeting at crossvein r. Crossvein r on line with crossvein s. Fork 1 absent. Forewing length 6.0 mm.

Male genitalia. Abdominal segment IX fused annularly, tergum slightly shorter than sternum ( Fig. 380). Anterior margins of segment IX regularly bow-shaped, dorsally sinuate in lateral view ( Fig. 380). Apical lobe on posterolateral margins right angled, located immediately above less sclerotized articulation cavity of gonocoxites; articulation cavity narrow ( Fig. 380). Spine row on posterior margin of segment IX almost continuous ( Fig. 380) and heterogeneous. Spines on dorsolateral spiny lobes longer than on apicoventral setose lobes; dorsolateral spiny lobes separate, shallowly protruding in dorsal view ( Fig. 381); located at intersegmental depression and dorsal rim; continuous with smooth lobe at dorsum of segment IX. Intersegmental step between segments IX and X stepwise, shallow, right angled. Segment X long, nearly triangular in lateral view ( Fig. 380); regularly quadrangular in dorsal view ( Fig. 381), slightly broadening apically ( Fig. 381); clearly monolobed in dorsal view; dorsal interlobular gap absent ( Fig. 381). Lateral sutures faint, transverse, crossing segment X obliquely ( Fig. 380). Longitudinal sutures associated with apicoventral setose lobes, meeting transverse sutures into Y. Smooth mesocaudal plate protruding at middle into small, rounded, mesal hump in dorsal view ( Fig. 381). Apicoventral setose lobes modified into small, lateral, dorsad curving, spiny processes ( Fig. 380). Lateral setose areas (superior or preanal appendages) forming small, circular, elevated setal wart; shifted distally; ventrally surrounded by longitudinal sutures of modified apicoventral lobes. Coxopodites exceeding apex of segment X; forming straight rod dilating gradually apicad ( Fig. 380); curving mesad in ventral view ( Fig. 382). Harpagones slightly curving dorsad; short in lateral view ( Fig. 380); in ventral view ( Fig. 382) nearly straight, parallel-sided; with serrate posterior margin ( Fig. 382). Phallotheca with welldeveloped, ventrad curving anterior part ( Fig. 380); dorsum concave. Endophallus forming narrow, long, tube; running through entire phallotheca; ending in sclerotized ring at gonopore. Chitinized endothecal process circular. Phallotremal sclerites vertically broad in lateral view. Vestigial ventral endothecal lobes membranous.
