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 : 232

Eoophyla minita sp. nov. ( Figs 49–50 , 57–58 )

Diagnosis. The species has the adults obvious smaller than other species of the group. It has the androconial hairs covered with apical 1/3 of the cell from the upper edge. In male genitalia, the species has two strong specialized setae about half length of vlava. In female genitalia, the species has the pair of signa shorter, at base of corpus bursae, about 1/7 length of it.

Description. Wing span ♂ 15–16 mm (n = 8), ♀ 17–27 mm (n = 13). Head pale yellow; antennae filiform, base with a side projection present in male; laibal 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; androconial hairs covered with apical 1/3 of cell from upper edge; a longitudinal brown fascia arising along inner margin; a triangular fuscous patch beyond discocellulares, with straight outer edge, touched with postmedial fascia; postmedial fascia band-like, fuscous; submarginal fascia yellow, with dark fuscous edges on both sides; cilia fuscous. Hindwing with base white; antemedial and posemedial fasciae yellow, with dark fuscous edges on both sides; an incision present below apex; three eyespots present along outer margin, with silvery scales centrally; submarginal fascia band-like, yellow, with black edges on both sides; cilia fuscous. Female same with male except androconial hairs absent.

Male genitalia ( Fig. 57 ). Uncus slender, with apex pointed; gnathos about 2/3 length of uncus, apex blunt, with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, nearly same width from base to apex, two strong specialized setae present at apex, about half length of vlava, apex not expanded; vinculum broad; saccus round; juxta plate-like, with apex incurved; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising below middle.

Female genitalia ( Fig. 58 ). Anal papillae relatively narrow, densely covered with setae; apophysis anterioris about 2 times length of anal papillae, apophysis posterioris little shorter than anterioris; antrum elongated, cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae about 1/3 length of corpus bursae, with many minute spines; corpus bursae long, with a pair of signa at base, consisting of many minute spines, about 1/7 length of corpus bursae.
