Wang, Shuxia, Xu, Zhixin & Li, Suran, 2022, Description of eight new species of the genus Irepacma Moriuti, Saito & Lewvanich (Lepidoptera: Autostichidae) from China, Zootaxa 5222 (1), pp. 37-48 : 40

Irepacma flaviptera Wang , sp. nov.

( Figs 4 , 12 )

Type material. CHINA, Zhejiang: Holotype ♁, Qianjiangyuan ( 30.39°N, 119.49°E), Mt. Tianmu , 866 m, 8.VII.2014, leg. AH Yin et al., slide No. LiSR16263.

Paratypes: 1♁, same data as holotype, slide No. XZX20376; Guizhou: 1♁, Xiannvtang, Mt. Leigong , 1553 m, 30.VII.2018, leg. ML Zheng et al., slide No. XZX20508 .

Diagnosis. The new species can be distinguished in the male genitalia by the costa with a short subquadrate process at the base, the sacculus distinctly narrowed at distal 1/3, the ventral margin of the valva roundly produced at basal 1/3, and the aedeagus with denticles and long thorns distally.

Description. Adult ( Fig. 4 ). Wingspan 14.0 – 14.5 mm.

Head yellow. Labial palpus and antenna yellow.

Thorax. Mesonotum and tegula yellow, with scattered yellowish brown scales at apex. Forewing yellow, covered with brown scales; discal, discocellular and plical stigmata dark brown; terminal dots brown; fringe yellow. Hindwing and fringe gray, tinged with yellow. Legs yellow, with brown scales.

Male genitalia ( Fig. 12 ). Uncus triangular, with setae medially. Gnathos circular, narrowly banded. Valva narrowed near base, subparallel medially, slightly narrowed from distal 1/4 to obtusely rounded apex, densely setose; ventral margin obtusely produced at basal 1/3; costa with subquadrate process at base, concave semicircularly beyond this process, widened at basal 2/5, then narrowed to before dorso-apex of valva. Sacculus about 2/5 length of valva, narrowed from wide base to basal 2/3, then distinctly narrowed, distal 1/3 triangular, narrowed to apex, with short setae. Saccus subtriangular, apex rounded. Aedeagus slightly shorter than valva, basal 1/4 slenderly clubbed, distal 3/4 wider, bifurcated from its half, forming two branches: one branch slender, clubbed, obtusely rounded at apex; the other branch gradually narrowed to its middle, then widened to apex, with teeth and spines distally.

Female unknown.

Distribution. China ( Guizhou, Zhejiang).

Etymology. The specific epithet is derived from the Latin flavus and - pterus, referring to the color of the forewing.
