description: Cheumatopsyche tungpa Oláh & Johanson, new species   
Fig. 325–328  
 This small brown animal is close to C. uchidai Kobayashi from Taiwan. Cheumatopsyche tungpa, new species is easily distinguished from that species in having a minute mesocaudal, smooth plate of segment X, being triangular in dorsal view and curving dorsad in lateral view. In addition, segment X is clearly dividing, with elevating basal half more sclerotized than at distal half. It also has slender harpagones, and the phallothecal apex is not capitate.   
Male. Body brown, with dense, lighter pubescence, especiallyt on legs. Maxillary palp formula I-(III, IV)- II-V, segment V as long as sum of segments I–IV. Head dorsum dark brown, with 9 clearly visible brown setal warts. Swollen setal wart absent on both proepisternum. Setal surface present on each precoxale. Pretarsal claws asymmetrical, laterally flanked by setal bundle. Mid- and hind-leg claws asymmetrical.  
Wings. Forewing membrane evenly brown, with slightly darker veins. Forewing crossveins m-cu and cu meeting in oblique line. Cu2 and A1 running separately before costa. Hind wing Sc and R meeting at crossvein r. Crossvein r on line with crossvein s. Fork 1 absent. Forewing length 5.0 mm.  
Male genitalia. Abdominal segment IX fused annularly, tergum slightly shorter than sternum (Fig. 325). Anterior margins of segment IX regularly bow-shaped, more dorsally flat in lateral aspect (Fig. 325). Apical lobe on posterolateral margins blunt, right-angled; located above less sclerotized articulation cavity of gonocoxite (Fig. 325). Spine row on posterior margin of segment IX intermittent and heterogeneous. Spines on dorsolateral spiny lobes 2 times longer than spines on apical lobes; in dorsal view, dorsolateral spiny lobes protruding into triangular (Fig. 325). Intersegmental step between segments IX and X pronounced, deep, right angled. Segment X medium sized, quadrangular in lateral view (Fig. 325). Step on dorsum of the segment X present, dividing segment into higher, more sclerotized basal part and lower, less sclerotized distal half; clearly bilobed in dorsal aspect, although smooth and slightly sclerotized mesocaudal plate produced into minute triangle (Fig. 326). Dorsal interlobular gap almost disappearing due to present of large apicoventral lobes. Sutures on both sides well developed; transverse, crossing segment X obliquely, reaching dorsal step (Fig. 325). Longitudinal sutures broad, forming continuation of apicoventral setose lobes; meeting transverse suture into X (Fig. 325). Smooth, mesocaudal plate reduced to minute, clearly dorsad curving triangle. Apicoventral setose lobes very long, parallel-sided, directed dorsad in lateral view (Fig. 325); in dorsal view (Fig. 326), broad with blunt apex, occupying entire intersegmental gap with lateral, subapical protuberances. Lateral setose areas (superior or preanal appendages) forming small, elevated, circular warts, located centrally on segment X. Coxopodites exceeding apex of segment X, forming nearly straight rods, ending in dilating apex; weakly bow-shaped in ventral view (Fig. 327). Harpagones curving dorsomesad (Fig. 325, 327), tapering. Phallotheca (Fig. 328) with straight dorsum and concave ventrum. Phallothecal apex not broadening ventrally. Endophallus long, running through entire phallotheca, ending in narrow tube at gonopore. Chitinized endothecal process ovoid. Phallotremal sclerites directed vertically narrow in lateral view. Vestigial, membranous, ventral endothecal lobes slightly visible.  
 Holotype male: TAIWAN: NanTowCo., Tungpu, 1000 m, shrub, 19.vi.1980 [D. R. Davis] - (NMNH). Paratype: TAIWAN: same data as holotype - 1 female (NMNH).   
 Distribution. Taiwan.   
 Etymology. tungpa, derived from the type locality, Tungpu.
