Polyphena chongzuoensis Li & Solovyev, 2019

Li, Wen-Tao, Solovyev, Alexey V. & Wang, Hou-Shuai, 2019, A new species of the genus Polyphena Solovyev, 2014 (Lepidoptera: Limacodidae) from China, Zootaxa 4664 (3), pp. 434-440 : 435-436

Polyphena chongzuoensis Li & Solovyev sp. nov.

( Figs. 3 , 7, 9, 10 , 11 )

Diagnosis. The new species is superficially similar to Parasa semperi Holloway, 1987 ( Figs. 4 , 8 ), but can be distinguished from the latter by the basal area of hindwing reddish brown, green patch of forewings with fuzzy margins, anellus in male genitalia has two rows of spines. Polyphena chongzuoensis sp. nov. and P. bana ( Figs. 2 , 6 ) are resembling each other in appearance, but the former has a much more reduced, small triangle greenish patch, the latter has a larger greenish patch reaching the costa of forewing. In male genitalia, the new species can be distinguished from P. bana by the shorter spurs of anellus and aedeagus with distinctly smaller apical process ( Figs. 9, 10 ).

Description. Male adult ( Figs. 3 , 11 ). Length of forewing 7–8 mm. Head brown, vertex with dense scales. Antennae brown, broadly bipectinate basally, filiform distally. Labial palpus upturned, scattered with yellow scales. Haustellum absent. Thorax green dorsally, with brown dorsal fascia in the middle. Forewing ground color brown, with a small green patch with fuzzy margins at the basal area; vein Sc relatively straight, R1 and R2 almost parallel, R3+4 branching from near the base of R5, with R3 extending to apex, M1 parallel to M2, M2 and M3 separated basally. Hindwing blackish brown; Rs and M1 stalked basally, M2 and M3 almost parallel. The tibial spurs formula is 0-2-2. Abdomen dark brown.

Male genitalia ( Figs. 7, 9, 10 ). Uncus claw-shaped, strongly sclerotized apically, broaden basally. Gnathos slen- der, stick-like laterally. Valvae long triangle-shaped, narrowing from base to apex. Saccus short, U-shaped. Juxta flattened, medially with a dorsal round incision. Anellus with two rows of spines dorsally. Aedeagus long, tubeshaped, with slightly developed apical process.

Type materials. Holotype: Male, 10-VI-2016, Jiangzhou District , Chongzou City, Guangxi Autonomous Re- gion, leg. Tiantian Yu (in SCAU) . Paratype: 1 male, same data as those of the holotype (in SCAU) .

Distribution. China (Guangxi Zhuang Autonomous Region).

Etymology. The species is named after the type locality.
