Wang, Mingqiang, Chen, Fuqiang, Zhu, Chaodong & Wu, Chunsheng, 2019, A supplemental description of the genus Lista Walker from China (Lepidoptera: Pyralidae), with two new and a newly record species, Zoological Systematics 44 (1), pp. 84-88 : 85

Lista furciillatusa Wang, Chen & Wu sp. nov. ( Figs 2–3 , 6–7 )

Diagnosis. The new species is similar to L. haraldusalis ( Walker, 1859) with a broad and serrated apex on the gnathos in the male genitalia, which is unique in the genus. But the new species has the folk-like lateral arms on the uncus, while spine-like ones in L. haraldusalis , which also distinguish this species from others of the genus.

Description. Adult male. Forewing length 9.0–10.0 mm (n = 3). Head mixed with fuscous and yellow; first and second segments of labial palpus with fuscous scales on outer side and yellow scales on inner side; third segment with pale brown scale; maxillary palpus yellow; antenna brown, scape extension yellow, mixed with more black scales on outer side. Thorax mixed with fuscous and yellow scales. Forewing covered with yellow, fuscous black and pink scales; central area mixed with pink and fuscous scales, postmedial fascia straight, yellow with black edge on inner side and brown edge on outer side, respectively, outer area covered with fuscous and pink scales; cilia brown. Hindwing with similar pattern as forewing.

Male genitalia. Uncus broad, suffused with dense setae, two folk-like lateral arms located. Gnathos broad and strongly sclerotized, apex serrated. Valva nearly same width from base to apex, terminal margin arc-shaped; costa slightly sclerotized; sacculus with two processes in middle, the inner one strong with apex serrated, the outer one small, thorn-like, a broad sclerotized plate from sacculus to center of valva. Juxta swollen, bifurcated with two pointed spines at apex. Phallus slender, slightly curved in middle, with a sclerotized plate-like cornutus.

Female genitalia. Unknown.

Material examined. Holotype ♂, China, Tibet, Medog, Beibeng (29.2486°N, 95.1751°E; elev. 1453 m), 11.VIII.2017, leg. Yi Li (gen. slide no. Ep740). Paratypes. 2♂, China, Tibet, Medog, Beibeng (29.3431°N, 95.1700°E; elev. 799 m), 20.VIII.2015, leg. Mingqiang Wang (gen. slide no. Ep750, Ep752) .
