Eoophyla fusca, Chen & Wu, 2019

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 : 228

Eoophyla fusca sp. nov. ( Figs 35–36 , 43–44 )

Diagnosis. The new species is very similar to E. sinensis , but has the ground color darker, the androconial hairs of forewing larger, the eyespots of hindwing smaller (but larger than other species of the group). It is also special by the upper edge of cell diffused with fuscous long setae on basal half and androconial hairs covered with apical half of the cell from the upper edge. In male genitalia, the species has the first specilized seta little longer than half of others, second and third setae little longer than half length of valva, third seta with minute spines laterally and a slightly expanded apex. The expanded apex of the third seta smaller than E. sinensis . In female genitalia, the species has the signa longer than E. sinensis .

Description. Wing span ♂ 22–28 mm (n = 88), ♀ 33–38 mm (n = 35). Head pale brown; antennae filiform, base with a side projection present in male; 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 dark brown, with basal half slightly paler; costa with basal half dark brown, covered with short setae; upper edge of cell diffused with fuscous long setae on basal half and androconial hairs covered with apical half of cell from upper edge; a longitudinal yellow fascia arising along inner margin; a triangular pale yellow patch beyond discocellulares, with outer edge slightly bended; postmedial fascia band-like, touched with triangular patch; submarginal fascia band-like, yellow, with fusous edges on both sides; cilia fuscous. Hindwing dark brown, with basal area white; antemedial fascia brown, with dark fuscous edge; white between ante- and postmedial fasciae; postmeidal fascia brown, with dark fuscous edges on both sides; an incision present below apex; three eyespots present along outer margin (smaller than E. siensis , but larger than others), with silvery scales centrally; submarginal fascia band-like, yellow, with dark fuscous edges on both sides; cilia fuscous. Female same with male except androconial hairs absent.

Male genitalia ( Fig. 43 ). Uncus slender, with apex pointed; gnathos about 3/4 length of uncus, apex with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely with setae, slight widen from base to apex, three strong specialized setae present at apex, first seta little longer than half of others, second and third setae little longer than half length of valva, third seta with minute spines laterally and a slightly expanded apex; vinculum broad; saccus round; juxta platelike, apex bifid; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 44 ). Anal papillae relativelyl narrow, densely covered with setae; apophysis anterioris and posterioris near same length, about 1.5 times as long as anal papillae; antrum cylindric; collar sclerotized; ductus seminalis arising below collar; ductus bursae relatively short, about 1/3 length of corpus bursae, with many minute spines; corpus bursae membranous, with a pair of signa, consisting of many minute spines, about 4/5 length of corpus bursae.

Distribution. China (Sichuan).

Etymology. The specific name is from the Latin “ fuscus ”, referring to its fuscous color.
