Type material.
Holotype: ♂, Baoshan City, Mt Gaoligongshan, Yunnan Province, China (98°47'42"E, 25°18'20"N; 1745 m elev.), 4 August 2018, coll. Zhou Yu (GUGC). Paratypes: 1♂, 6♀♀, same data as holotype.
Diagnosis.
The new species can be distinguished from other Idioscopus species by the combination of the following features: anal tube short; style apophysis with a row of three or four subapical teeth along inner margin; aedeagal shaft with long, recurved, hook-like apical processes.
Description.
Coloration. Ground coloration translucent brown. Vertex pale brown with two round spots close to the adjacent eyes (Fig. 1A View Figure 1 ). Eyes and ocelli brown (Fig. 1A-C View Figure 1 ). Face (Fig. 1B, C View Figure 1 ) yellowish white, narrow area along inner margin of eye, area surrounding bases of antennae, and inner margins of gena along frontal suture black, upper area with dark brown semicircular marking. Pronotum (Fig. 1A View Figure 1 ) yellowish brown along anterior margin, posterior two-thirds brown, with a brown U-shaped band medially. Mesosternum (Fig. 1A View Figure 1 ) black, mesepimeron with black spot. Mesonotum (Fig. 1A View Figure 1 ) yellow with pair of triangular, laterobasal, black maculae. Forewing with veins brown (Fig. 1A View Figure 1 ).
External features as in generic description with face and pronotum shagreen and crown finely transversely rugose. Male antennae without apical disc. Forewing (Fig. 1D View Figure 1 ) with two subapical cells; inner subapical open.
Male genitalia. Male pygofer (Fig. 1E, F View Figure 1 ) without ventral process; anal collar thin with apex upturned; anterodorsal apodemes well developed. Anal tube (Fig. 1E View Figure 1 ) short. Subgenital plates (Fig. 1E View Figure 1 ) of uniform width, with reduced hair-like marginal setae. Connective (Fig. 1G View Figure 1 ) T-shaped, with stem narrow. Style apophysis (Fig. 1G View Figure 1 ) with a row of three or four tooth-like projections along inner margin subapically, outer margin with macrosetae in distal one-third. Aedeagus (Fig. 1H, I View Figure 1 ) with shaft laterally compressed, with pair of long, recurved, hook-like processes subapically from ventral margin, acute apically; basal apodeme pillar-like in lateral view, distally and laterally expanded in ventral view.
Female genitalia. Posterior margin of sternite VII (Fig. 3A View Figure 3 ) slightly produced medially. Valvulae as in Figure 3B-E View Figure 3 .
