Revision of the Oriental and Afrotropical species of Cheumatopsyche Wallengren (Hydropsychidae, Trichoptera) Author Oláh, János Author Johanson, Kjell Arne Author Barnard, Peter C. text Zootaxa 2008 2008-03-31 1738 1 171 journal article 1175­5334 Cheumatopsyche kala Oláh & Johanson , new species Fig. 236–239 This species is similar to C. copiosa Kimmins from Central Africa but segment X is broad in both lateral and dorsal view; the dorsad orienting apicoventral setal lobes are much longer; the harpagones have a filiform process; and the phallotheca is not constricted at mid-length. The most striking feature of this dark species is the symmetrical protarsal claws, with no laterally flanking setal bundle. Male. Body and wings dark brown, some part almost black; wing without spots or pattern. 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 dark brown with 7 paler warts. Proepisternum without swollen setal wart. Each protibiae with 2 spurs. Protarsal claws symmetrical, without lateral setal bundle. Forewing length 10.0 mm, hind wing length 7.5 mm . Forewing crossveins m-cu and cu forming unbroken line. Hind wing fork I absent. FIGURES 231–235. Cheumatopsyche fahara Oláh & Johanson , new species , holotype. 231 — genitalia, lateral; 232 — genitalia, dorsal; 233 — gonocoxite, ventral; 233 — gonocoxite, dorsal; 235 — phallus, lateral. Male genitalia. Segment IX fused annularly; tergum longer than sternum ( Fig. 236 ); anterior margins of segment IX regularly convex, more extended dorsally; apical lobe on posterolateral margins weakly developed, located above base of coxopodites; spine row on posterior margins of segment IX complete; spines on dorsum twice as long as others. Intersegmental depression between segment IX and segment X absent. Segment X broad ( Fig. 236 ), with fused, well delineated, dorsad curving apicoventral setal lobes ( Fig. 236 ); in dorsal view ( Fig. 237 ) apicoventral setal lobes fused into broad, rounded, wing-shaped processes surrounding shallow dorsal interlobular gap ( Fig. 237 ). Lateral interlobular gaps absent. Setaless mesocaudal lobe reduced; posterior margin concave, forming base of dorsal interlobular gap. Lateral setose areas produced into pair of elongating warts ( Fig. 237 ), situated behind transverse sutures at mid-height on segment X. Short transverse sutures forming Y with longitudinal sutures ( Fig. 236 ). Coxopodites parallel-sided, except dilated at apices; nearly straight in lateral view ( Fig. 236 ); in ventral view ( Fig. 238 ), very slender near base, gradually widening apically, slightly curving mesad from mid-length. Harpagones short, almost as wide as coxopodites in lat- eral view ( Fig. 236 ); each with short filiform process at apicolateral corner. Phallotheca ( Fig. 239 ) with large phallobase; horizontal shaft short, gradually narrowing distad along proximal three-quarts; sclerotised endothecal process narrow, elongated; phallotremal sclerites broad; vestigial ventral endothecal membranous lobe visible. Holotype male: MADAGASCAR : Mt. Tsaratanana , 1700 m , x.1950 [ R. Paulian ] ( MNHN , in alcohol). Distribution: Madagascar . Etymology: after its very dark colour, black “kala” in Sanscrit.
