Cheumatopsyche nohondoan Oláh & Johanson , new species
Fig. 105, 147–150
The species is similar to C. doan , new species but is distinguished in the apicoventral lobes being straight and parallel, not bulbous in dorsal view; the preanal appendages are not developed into long digitiform processes, nor sharply cut at their apices; the forewing membrane pattern is reduced to small, light patches; the forewing crossveins m-cu and cu are separate, and the hind wing fork I is absent.
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 sum of segments I–IV. Head dorsum dark brown, with 7 visible, slightly lighter warts. Swollen setal wart absent on proepisternum. Protarsal claws asymmetrical, laterally flanked by setal bundles. Forewing length 6.1 mm, hind wing length 5 mm. Hind wing fork I absent. Forewing with light pattern of 2 large patches on both anterior and posterior margins ( Fig. 105).
Male genitalia. Segment IX fused annularly; tergum short, sternum slightly longer than tergum ( Fig. 147); anterior margins of segment IX regularly convex in lateral view ( Fig. 147); apical lobe on posterolateral margins both triangularly rounded, located immediately above base of coxopodites; spine row on posterior margins of segment IX complete, spines on dorsocaudal spiny lobes more than 3 times longer than other spines. Intersegmental step between segment IX and segment X sloping, shallow and obtusely angled ( Fig. 147). Segment X long, quadrangular in dorsal and lateral views ( Figs. 147, 148); clearly bilobed in dorsal view ( Fig. 148). Transverse sutures crossing segment ( Fig. 147). Longitudinal sutures form continuation of apicoventral setal lobes ( Fig. 147). Setaless mesocaudal lobe slightly excised in middle ( Fig. 148). Apicoventral setal lobes curving dorsad, with blunt digitate lobe; both apices parallel-sided in dorsal view ( Fig. 148). Pair of lateral setose areas forming elevated warts ( Fig. 148); located beyond transverse sutures and above longitudinal sutures ( Fig. 147). Coxopodites extending beyond apex of segment X, straight, each apices slightly dilating ( Fig. 147). Harpagones broad at base, both tapering into hook-like apices in lateral and ventral view ( Fig. 147, 149). Phallothecal dorsum ( Fig. 150) concave, constricted at mid-length; sclerotised endothecal process with
small apicoventral projection; phallotremal sclerites broad, vertical in lateral view ( Fig. 150).
Holotype male: VIETNAM: Quang Nam Da Nang Province: Lo Xo Pass , 15.ii.2006, light [J. Oláh Jr. & Z. Ecsedi] ( OPC, in alcohol).
Distribution: Vietnam (Quang Nam Da Nang Province).
Etymology: named after the reduced light pattern on the forewing, less “nohon” pattern “doan” in Vietnamese. There is much less pattern on the forewing than in C. doan .
