Type materials.

Holotype: China • ♂; Yunnan, Jinghong, Mt Jinuo; 21.98°N, 100.89°E; 1425 m elev.; 6 Aug. 2022; S Yu & KJ Teng leg.; slide no. YUS064, LCU. Paratype: 1♂; same data as holotype; slide no. YUS060, LCU.

Diagnosis.

The new species can be distinguished by the triangular apical process of the sacculus which extends for less than 1/2 the length of the cucullus, and by the aedeagus which has dorsal and ventral extensions at the apex; in W. similangoonae and W. angoonae , the apical process of the sacculus is long, extending posteriorly at least as far as the apex of the cucullus (sometimes further). Woonpaikia villosa has a transverse fascia in the hindwing ( Park 2010: 240, fig. 1), whereas W. imperspicua lacks this fascia.

Description.

Wingspan 13.5-14.0 mm (Figs 1D , 2A ). Head brown. Antenna orange white; scape with a small imperceptible pectin-like scale tuft ventrodistally. Labial palpus dorsally with dense, long, hair-like scales; third palpomere shorter than second palpomere. Forewing slightly widened distally, costal margin almost straight, apex produced, termen gently concave; ground color dark brown; orange-yellow along costal margin from before middle to apex; discal stigma black, small, rounded; plical stigma black; discocellular stigma black, larger than plical stigma; fringe greyish brown, with an orange-white basal line; R3, R4 and R5 stalked, R5 to termen, CuA1 and CuA2 with short stalk. Hindwing and fringe pale greyish brown; M3 and CuA1 stalked.

Male genitalia (Fig. 3B ). Uncus with caudal lobes thumb-shaped. Gnathos with basal plate distally semi-ovate, with rounded apex; median process almost uniformly wide in basal 2/3, thereafter sharply narrowed to a pointed apex, curved ventrad at basal 2/3 by a right angle. Costal bar narrow, taenioid. Valva with basal part subquadrate; cucullus arising from upper corner of basal part of valva, narrowed at base, widened to middle, width at middle about twice width of base, thereafter narrowed to blunt apex, nearly straight on costal margin, bearing a row of needle-like setae along ventral margin; sacculus wide, straight on its ventral margin, with a triangular apical process extending less than 1/2 length of cucullus and bearing a row of needle-like setae. Juxta elliptical, wider than long, with a subquadrate process at middle on anterior margin. Vinculum rounded on anterior margin. Aedeagus slightly shorter than valva, almost uniformly wide, with a horn-like dorsal extension and a spiniform ventral extension; cornuti consisting of a flake-like plate placed beyond middle and three spinules near apex.

Female. Unknown.

Distribution.

China (Yunnan).

Etymology.

The specific name is derived from the Latin imperspicuus, referring to the small imperceptible pectin-like scale tuft on the scape of the antenna.
