description: Cheumatopsyche junolahi Oláh & Johanson, new species   
Fig. 361–364  
 This species is similar to C. schwendingeri Malicky & Chantaramongkol from Thailand, especially in the presence of a pair of very large lateral setal areas covering large parts of segment X and with short, strong setae. Cheumatopsyche junolahi is easily separated from C. schwendingeri in dorsal view by the broader and parallel-sided segment X; the long, dorsad curving apicoventral setal lobes forming sharply triangular apices in dorsal view; and the harpagones that are broader and more robust. In addition, the body and forewings of C. junolahi are a very dark brown to fuscous, not light brown or yellowish as in C. schwendingeri.   
Male. Body and wings dark brown, almost fulvous with brown pubescence; wings with no 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 similarly coloured warts. Proepisternum without swollen setal wart. Each protibiae with 2 spurs. Protarsal claws asymmetrical, laterally flanked by setal bundle. Forewing length 7.1 mm, hind wing length 5.8 mm. Hind wing fork I absent. Distance between forewing crossveins m-cu and cu equal to 1.5 times length of crossvein m-cu.  
Male genitalia. Segment IX fused annularly, short; sternum twice as long as tergum (Fig. 361); anterior margin of segment IX shallowly convex, straight at mid-height (Fig. 361); apical lobe on posterolateral margins nearly right-angled, very short, located immediately above base of coxopodites; spine row on posterior margins of segment IX complete, with long, stiff spines. Intersegmental step between segment IX and segment X shallow, obtuse-angled in lateral view (Fig. 361). Segment X long, slender, quadrangular in lateral view (Fig. 361); broad, quadrangular in dorsal view (Fig. 362). Dorsal and lateral interlobular gaps absent. Setaless mesocaudal lobe reduced, with slightly concave posterior margin (Fig. 362). Pair of lateral setose areas covering large areas behind transverse and above longitudinal sutures (Fig. 361). Transverse sutures very pronounced, running obliquely in lateral view (Fig. 361). Longitudinal sutures strongly sclerotised, forming continuation of apicoventral lobes (Fig. 361); running well above and parallel with ventral margin of segment X. Coxopodites robust, slightly dilating distad from basal one-third, with almost parallel-sided distal one-third (Fig. 361); dorsal margins strongly convex near apices; in ventral view slightly curving mesad along their lengths; narrowest at basal one-third (Fig. 363). Harpagones broad, in lateral view nearly drop-shaped (Fig. 361); in ventral view parallelogram-shaped, slightly curving mesad (Fig. 363). Phallotheca (Fig. 364) straight, narrowing towards mid-length before slightly broadening apicad; phallobase shallow; sclerotised endothecal process rounded with small incision at ventral margin; phallotremal sclerites exceeding ventral margin of endothecal process, not covered by endothecal process; vestigial ventral, endothecal membranous lobe present.  
 Holotype male: VIETNAM: Thua Thien Hue Province: Bach Ma National Park, 700 m, 22.ii.2006, light trap [J. Oláh Jr & Z. Ecsedi] (OPC, in alcohol).   
 Distribution: Vietnam.   
 Etymology: named in honour of the collector, János Oláh Jr. for operating light traps during bird survey activities in some very remote areas in Vietnam.
