description: Cheumatopsyche quadrifasciata Oláh & Johanson, new species   
Fig. 106, 151–154  
 This species is similar to C. afra (Mosely) in the genitalic morphology, but the harpagones are more slender in lateral and ventral view. The 2 species are easily separated also in the forewing pattern, present in C. quadrifasciata as 4 white fasciae that are absent in C. afra.   
Male. Body and wings brown with pale 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 7 visible, slightly paler warts. Proepisternum without swollen setal wart. Protarsal claws asymmetrical, laterally flanked by setal bundle. Each protibiae with 1 spur. Forewing length 6.4 mm, hind wing length 4.9 mm. Forewing crossvein m-cu and cu tangental. Hind wing fork I absent.  
Male genitalia. Segment IX fused annularly; tergum and sternum equally long; anterior margins of segment IX uniformly convex in lateral view (Fig. 151); apical lobe on posterolateral margins well developed, triangular, long, located above and partially covering base of coxopodites (Fig. 151); spine row along posterior margins of segment IX continuous, spines on dorsocaudal lobes longer than other spines. Intersegmental step between segment IX and segment X deep (Fig. 151). Segment X quadrangular in lateral and dorsal view, clearly bilobed (Fig. 152). Transverse sutures crossing segment X (Fig. 151). Longitudinal sutures forming continuation of apicoventral setal lobes (Fig. 151). Setaless mesocaudal lobe straight-cut apically with sharpangled tip in lateral view (Fig. 151). Apicoventral setal lobes nearly straight in lateral view (Fig. 151), curving mesad in dorsal view (Fig. 152); slightly narrowing toward apices, rounded. Pair of lateral setose areas reduced to small, elevated, circular warts located well beyond transverse sutures distally on segment X, near apical end of dorsomesal margins (Fig. 151). Coxopodites slightly extending beyond apex of segment X; straight, with weakly dilated apices. Harpagones slender along their lengths, arising from ventral corner of coxopodites (Fig. 151); slightly sigmoid in lateral and ventral view (Fig. 151, 153). Phallothecal dorsum (Fig. 154) straight, constricted at midlength; sclerotised endothecal process shortened, as broad as phallothecal apex; phallotremal sclerites rounded in lateral view.  
 Holotype male: TANZANIA, USA River, ix.1965 – ii.1966, light [J. Szunyoghy] (HNHM, in alcohol).   
 Paratypes: same data as holotype — 42 males (HNHM, in alcohol), 6 males (OPC, in alcohol).   
 Distribution: Tanzania.   
 Etymology: named after the four striking white bands on the forewing, four “ quadri ”, band “ fascia ” in Latin.
