description: Cheumatopsyche agnetae Oláh & Johanson, new species   
Fig. 43–46  
 This species is similar to C. criseyde Malicky from Thailand, and C. kim Oláh & Johanson, new species from Vietnam. Cheumatopsyche agnetae is easily separated from the 2 species by the narrowly and sharply triangular setaless mesocaudal lobe on segment X being much shorter than the apicoventral lobes; these lobes dominating distal part of segment X in lateral and dorsal views. The harpagones are basally convex in ventral view as in C. criseyde, not tapering sharply as in C. kim. The shaped of segment X in dorsal view is the most striking feature of this species. Similar shape of segment X is known in C. trifasciata Li & Dudgeon from the Fujian Province in China, but that species has forewings with 3 white fasciae, and the phallic apparatus lacks the subapical ventral broadening.   
Male. Body and wings brown with brown pubescence. Maxillary palp segment I shortest, segment II longer, segments III and IV equally long, segment V as long as segments I–IV together. Head dorsum darker brown, with 9 slightly lighter warts. Swollen setal warts absent from proepisternum. Protarsal claws asymmetrical, laterally flanked by setal bundle. Forewing length 6 mm, hind wing length 4.5 mm. Hind wing fork I absent.  
Male genitalia. Segment IX fused annularly; tergum short, sternum 3 times longer than tergum (Fig. 43); anterior margins of segment IX almost regularly curving in lateral view, slightly more produced ventrally (Fig. 43); apical lobe on posterolateral margins short, located immediately above base of coxopodites (Fig. 43), posterolateral margins nearly straight; spine row on posterior margins of segment IX continuous. Intersegmental step between segment IX and segment X short, almost absent. Segment X well developed, subquadrangular in lateral view (Fig. 43); in dorsal view (Fig. 44) narrowing towards mid-length before strongly widening at distal three-fourths its length, clearly trilobed in dorsal view. Setaless mesocaudal lobe narrowly triangular in dorsal view (Fig. 44). Apicoventral setal lobes forming long, almost straight, obliquely directed and heavily sclerotised finger-like processes (Fig. 43); geniculate in dorsal view (Fig. 44), directed mesad, almost touching mesally. Pair of lateral setose areas forming tuboid elevated warts clearly visible in dorsal and lateral view (Fig. 43, 44), located ventrally immediately after mid-length of segment X. Transverse and longitudinal sutures well-developed. Coxopodites slightly exceeding apex of segment X (Fig. 43), straight, with slightly dilating apices (Fig. 43); in ventral view (Fig. 45) slender at mid-length, gradually dilating apically and curving mesad. Harpagones slender, gradually tapering from base into sharply dorsad pointing apices in lateral view (Fig. 43), less pointed and curving mesad in ventral view (Fig. 45). Phallothecal dorsum straight (Fig. 46); sclerotised endothecal process half-ovoid; phallotremal sclerites broad, vertical in lateral view; with short, sub-apical, ventrally rounded broadening about as large as sclerotised endothecal process.  
 Holotype male: HONG KONG, Sai Kung East Country Park, stream 500 m N Tai Mun Shan Mt., at Tai Long Au, Malaisetrap, loc 1, 20–27.v.2005 [A. Olsson & E. Ohlsson] (NRM, in alcohol).   
 Distribution: Hong Kong.   
 Etymology: after the first collector, Agneta Olsson.
