Chen, Fuqiang & Wu, Chunsheng, 2019, A taxonomic review of the genus Eoophyla Swinhoe, 1900 (Lepidoptera: Crambidae: Acentropinae) from China, Zoological Systematics 44 (3), pp. 212-239 : 233-234

Eoophyla leiokellula sp. nov. ( Figs 23 , 68 )

Diagnosis. The species is obvious different with other species of the group by following: the androconial hairs absent, the triangular fuscous patch beyond discocellulares not touched with postmedial fascia. In male genitalia, the species is specifical by its valva with a tuft of specialized setae rather than strong specialized setae and the gnathos with a slightly expanded apex.

Description. Wing span ♂ 27 mm (n = 1). Head pale brown; antennae filiform, base without side projection present; labial palpi upturned, as long as compound eyes, densely suffused with long scales in ventral. Thorax and abdomen brown. Legs and tarsi slender.

Male. Forewing brown, little paler in basal half; upper edge of cell diffused with brown long setae in basal half, without androconial hairs; a longitudinal brown fascia arising along inner margin; a triangular fuscous patch beyond discocellulares, with outer edge waved, not touched with postmedial fascia; postmedial fascia band-like, fuscous; submarginal faicia bandlike, yellow, with dark fuscous edges on both sides; cilia fuscous. Hindwing with basal half white; antemedial fascia brown, with fuscous outer edge; postmedial fascia brown, with fuscous edges on both sides; an incision present below apex; three eyespot present along outer margin, with silvery scales centrally; submarginal fascia band-like, yellow, with black edges on both sides; cilia fuscous.

Male genitalia ( Fig. 68 ). Uncus slender, thinner than gnathos, with apex pointed; gnathos about 2/3 length of uncus, apex slightly expanded, round, with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, nearly same width from base to apex, apex constricted, a tuft of specialized setae present at apex; vinculum broad; saccus round; juxta plate-like, with apex bilobed; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female. Unknown.

Material examined. Holotype (♂). Yunnan, Jinping, Hetouzhai , 1700 m, 1956.V.14, Huang Keren , deposited in IZCAS.

Distribution. China (Yunnan).

Etymology. The specific name is from Greek “ lei ” and “ kello ”, corresponding to the androconial hairs absent in the new species.
