Type material. CHINA: Holotype ♂, Mt. Gaoligong [24.83°N, 98.77°E], Baoshan, Yunnan Province, 2157 m, 21.vii.2015, coll. Kaijian Teng and Xia Bai, genitalia slide no. CPX15185.
Paratype: 1 ♀, Dahaoping, Tengchong, Yunnan Province, 2020 m, 5.viii.2007, coll. Dandan Zhang, genitalia slide no. CPX15176.
Diagnosis. This species is characterized by the forewing having seven shining yellowish brown, unequally sized and spaced streaks along costal margin, the dorsum with two yellowish brown bands extending obliquely upward and joined with the forth, fifth and sixth costal streaks (Fig. 3 f), and the ductus bursae with posterior 3/5 sclerotized on dorsal surface in the female genitalia (Fig. 5 c). Anthonympha reniforma sp. nov. is closer to A. trapezia sp. nov. in the male genitalia, and the differences between them are stated under the latter species.
Description. Adult (Fig. 3 f): Wingspan 14.0‒15.0 mm. Head snowy white. Antenna with scape white, pecten brown; flagellum greyish white except basal four flagelomeres brown dorsally. Labial palpus white, with first and second palpomeres deep greyish brown on outer surface. Thorax white, with a pale brown transverse band before posterior margin. Tegula white, with a brown spot basally. Forewing with M3 and CuA1 separated; white; costal margin with approximately seven shining yellowish brown streaks unequally sized and spaced: basal two streaks and seventh streak triangular, third streak smallest, subsemicircular, forth to sixth streaks wider, quadrate, combined posteriorly, yellowish brown dot at distal 1/7 and apex respectively; dorsum with transverse yellowish brown bands at basal 1/3 and 2/3 respectively, obliquely extending upward and joined with forth to sixth costal streaks from costa, with blackish brown scales medially, inner band wider, subrectangular, slightly narrowed medially, outer band narrower, sinuate on outer margin; the area from outer margin of second band to apex scattered with yellowish brown scales; cilia white, brown along costal margin. Hindwing with M3 and CuA1 stalked; basal half white, distal half pale grey; cilia white except pale brown along costal margin. Foreleg deep greyish brown, mixed with white scales on coxa; mid- and hindlegs yellowish white, midleg with tibia covered with brown scales distally, tarsi of mid- and hindlegs brown at apex of each segment on outer side. Abdomen deep grey mixed with white scales on dorsal surface, silvery white on ventral surface.
Male genitalia (Fig. 4 e): Socius slender, basal 2/5 wide, almost uniform, distal 3/5 gradually narrowed to pointed apex, curved ventrad in a hook distally. Tuba analis membranous, ventro-median sclerotized band from near base to middle. Gnathos with a large forked process posteromedially. Valva kidney-shaped, narrowed basally, widened medially, gradually narrowed distally, bluntly rounded apically. Saccus short, rounded apically. Aedeagus 1.7 times length of valva, straight; cornutus being a thorn, curved basally, about 2/5 length of aedeagus, placed near middle.
Female genitalia (Fig. 5 c): Apophyses anteriores as long as apophyses posteriores. Lamella postvaginalis being a sclerotized band, its posterior margin concave at middle, lined with long setae. Antrum wider than long, being a sclerotized ring; ductus bursae nearly as long as corpus bursae, narrowed medially, posterior 3/5 sclerotized on dorsal surface, anterior 2/5 membranous; ductus seminalis elliptical, larger than corpus bursae. Corpus bursae elongate, gradually expanded anteriorly, pear-like in shape.
Distribution. China (Yunnan).
Etymology. The specific name is derived from the Latin adjective reniformis, meaning kidney-shaped, referring to the shape of the valva in the male genitalia.
