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 : 229-232

Eoophyla clarusa sp. nov. ( Figs 47–48 , 55–56 )

Diagnosis. The species is different by the forewing of male has its upper edge of cell diffused with fuscous setae from base to 2/3 length, and androconial hairs covered with apical 1/3 of the cell from the upper edge. In male genitalia, the species has two short strong specialized setae about 1/3 length of valva. In female genitalia, the species has the pair of slender signa about 2/3 length of corpus bursae.

The species is very similar to E. abstrusa , but has the triangular patch on forewing with clear outer edge while blurry in the latter. Moreover, the species has the androconial hairs obvious smaller than E. abstrusa . In genitalia, the species has the specialized setae and the signa shorter than those of E. abstrusa .

Description. Wing span ♂ 27–29 mm (n = 5), ♀ 27–35 mm (n = 12). Head pale yellow brown; antennae filiform, base with a side projection present in male; labial palpi upturned, little longer than compound eyes, densely suffused with long scales in ventral. Thorax and abdomen brown. Legs and tarsi slender.

Male. Forewing rufous, little paler in basal half; upper edge of cell diffused with fuscous long setae from base to 2/3 length, and 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 outer edge straight; postmedial fascia band-like, fuscous, surrounding a triangular white patch with triangular fuscous patch; submarginal fascia band-like, yellow, with black edges on both sides; cilia fuscous. Hindwing with basal half white; antemedial fascia rufous, with dark fuscous outer edge; postmedial fascia rufous, 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. 55 ). Uncus slender, with apex pointed; gnathos about 2/3 length of uncus, with several dorsal teeth; tegumen with sclerotized dorsal ridge X-shaped; valva densely covered with setae, nearly same width from base to apex, two short strong specialized setae present at apex, about 1/3 length of valva; vinculum broad; saccus round; juxta plate-like, with apex bilobed; aedeagus slender, vesica with many minute spines, ductus ejaculatorius arising from middle.

Female genitalia ( Fig. 56 ). Anal papillae relatively broad, densely covered with setae; apophysis anterioris about 1.5 times as long as anal papillae, apophysis posterioris little shorter than anterioris; antrum elongated, cylindric; collar sclerotized; ductus seminalis arising bellow collar; ductus bursae about half length of corpus bursae, with many minute spines; corpus bursae long, with a pair of slender signa, consisting of many minute spines and about 2/3 length of corpus bursae.

Distribution. China (Fujian, Guangxi, Yunnan).

Etymology. The specific name is from the Latin “ clarus ”, means clear, corresponding to its clear edges of the triangular patch on forewing, different from E. abstrusa .
