Irepacma bispicifera Wang, sp. nov.

(Figs 1, 9)

Type material. CHINA, Fujian: Holotype ♁, Tongmu Village (27.75°N, 117.69°E), Mt. Wuyi, 2.V.2014, leg. XF Yang, slide No. LiSR16231.

Diagnosis. The new species can be distinguished by the following male genital characters: i) the sinuate ventral margin of the valva distinctly concave beyond the middle, and ii) the aedeagus with two densely spiny spicate distal processes that exceed its the apex.

Description. Adult (Fig. 1). Wingspan 21.0 mm.

Head yellowish brown. Labial palpus in male yellow on inner surface; first palpomere with black scales and second one blackish brown on outer surface. Antenna yellow on ventral surface; on dorsal surface, scape black, flagellum black and yellow.

Thorax. Mesonotum and tegula dark grayish brown. Forewing brown; fringe dark brown, with a yellow basal line along costal margin and termen. Hindwing dark brown; fringe brown. Legs yellow with exceptions on ventral surface: coxa of foreleg dark brown, coxa of midleg with brown scales; on dorsal surface, femur and tibia of foreleg black, tibia of midleg mixed with brown, tarsi of fore- and midlegs black at base of first tarsomere; on outer surface: tibia of hindleg with dense gray scales at base and near apex, first tarsomere grayish brown at base.

Male genitalia (Fig. 9). Uncus conical, tapered from wide base to narrowly rounded apex; lateral margin sclerotized, with sparse setae near base. Gnathos membranous, banded. Valva wide at base, slightly narrowed medially, gradually narrowed from distal 1/4 to obliquely obtuse apex, setose distally; ventral margin sinuate, slightly convex basally, distinctly concave medially, with dense setae from beyond middle to apex; costa banded, exceeding dorso-apex of valva, with a triangular process at base. Sacculus triangular, apex heavily sclerotized, weakly hooked, with short setae. Saccus with basal 1/3 uniformly wide, gradually narrowed from basal 1/3 to narrowly rounded apex. Juxta subquadrate, concave medially on posterior margin, forming two thumb-shaped posterolateral lobes. Aedeagus slightly longer than valva, parallel-sided from basal 1/3 to 2/3, distal 1/3 spatulate, with two densely spiny spicate processes exceeding its apex.

Female unknown.

Distribution. China (Fujian).

Etymology. The specific epithet is derived from the Latin bi - and spicifera, referring to the two spicate processes of the aedeagus.
