Cheumatopsyche montapo Oláh & Johanson , new species

Fig. 349–352

This species is similar to C. bardiana Malicky from Nepal, and C. hoasena Oláh & Johanson from Vietnam. It is separated from the 2 species in the dorsum of segment X lacks the sharply acute-angled elevation in lateral aspect. It also differs in lateral view by having narrow and long body of segment X, not wide and short as in the other species. The coxopodites of C. montapo are sinuate, not straight as in C. bardiana and C. hoasena . The harpagones are basally broad and tapering distad, while uniformly slender in C. hoasena , and expanded ventrad in C. bardiana .

Male. Body and wings pale brown, with brown pubescence. Maxillary palp formula I-(III, IV)-II-V, segment V as long as sum of segments I–IV. Head dorsum dark brown, with 9 slightly lighter warts. Swollen setal wart absent on proepisternum. Setal wart present on precoxale. Pretarsal claws asymmetrical, laterally flanked by setal bundle.

Wings. Forewing evenly light speckled with darker veins. Forewing crossveins m-cu and cu almost tangential. Hind wing fork 1 absent. Forwing length 6.7 mm; hind wing length 4.9 mm.

Male genitalia. Abdominal segment IX fused annularly, tergum short, sternum 3 times longer than tergum ( Fig. 349). Anterior margins of segment IX regularly bow-shaped, nearly flat dorsally in lateral aspect ( Fig. 349). Apical lobe on posterolateral margins blunt right-angled, located above less sclerotized articulation cavity of gonocoxite. Spine row on posterior margin of segment IX intermittent and heterogeneous. Spines on dorsolateral spiny lobes 2 times longer than spines on apical lobes. Intersegmental step between segments IX and X shallow, right angled. Segment X long, nearly triangular in lateral view ( Fig. 349), somewhat quadrangular in dorsal aspect, broadening apically ( Fig. 350); clearly bilobed in dorsal aspect. Dorsal interlobular gap wide and deep. Transverse suture on each side crossing segment X obliquely. Longitudinal suture on each side forming continuation of apicoventral setose lobes; meeting transverse sutures into Y. Smooth dorsomesal plate straight. Apicoventral setose lobes fusing with segment X along mesal margin; apex free in lateral view ( Fig. 349), curving slightly mesally, tapers in dorsal view ( Fig. 350); setae restricted to apical tips. Lateral setose areas (superior or preanal appendages) forming large, elevating wart, surrounded basally by apicoventral setose lobes. Coxopodites exceeding apex of segment X; forming straight rod; with slightly sinuous margins ( Fig. 349); apices dilating in lateral aspect ( Fig. 349); weakly curving mesad in ventral view ( Fig. 351). Harpagones each with broad basal half; tapering at distal half in lateral view ( Fig. 349); straight and tapering in ventral view ( Fig. 351). Phallothecal dorsum straight ( Fig. 352). Chitinized endothecal process elongating, curving ventrad, tapering ventrocaudad. Phallotremal sclerites broad, vertical, in lateral view. Vestigial, membranous, ventral endothecal lobes slightly visible.
