Two new genera and three new species of Epipaschiinae Meyrick from China (Lepidoptera, Pyralidae) Author Wang, Mingqiang Author Chen, Fuqiang Author Zhu, Chaodong Author Wu, Chunsheng text ZooKeys 2017 722 87 99 http://dx.doi.org/10.3897/zookeys.722.12362 journal article http://dx.doi.org/10.3897/zookeys.722.12362 1313-2970-722-87 C7EA4AAE64484FCEADF11BF5F99C8B23 C7EA4AAE64484FCEADF11BF5F99C8B23 Arcanusa apexiarcanusa Wang, Chen & Wu sp. n. Figs 1, 7, 14 Differential diagnosis. The new species is very similar to Ar. sinuosa comb. n. in external characters, especially the forewing. However, the hindwing is obviously paler than the forewing in the new species, while lightly paler in Ar. sinuosa . In male genitalia, Ar. apexiarcanusa Wang, Chen & Wu, sp. n. has the gnathos beaked and the sacculus with a bifurcated stick-like process while Ar. sinuosa has the gnathos trifurcate with a spine-like apex and the sacculus has a spine-like process. In addition, there are more minute spines on the juxta of the new species than on that of Ar. sinuosa . Figures 1-6.

Scale bars: 5.0 mm. Description. Adult male. Forewing length 15.5 mm (n=1). Head yellow mixed with fuscous; first and second segments of labial palpus with fuscous scales on outer side and pale yellow scales on inner side; third segment with pale brown scales; antenna yellow, scape extension fuscous, mixed with black scales on outer side and pale yellow scales on inner side; apical 2/3 of scape extension with yellow hair-like scales. Thorax mixed with yellow and small number of brown scales. Forewing covered with pale yellow, yellow and black scales; base black mixed with yellow scales, antemedial line black, waved, a black patch above discocellular; central area suffused with yellow scales; postmedial line black, waved, arched outward medially; outer area covered with yellow scales; cilia mixed with yellow and brown. Hindwing pale fuscous, with a blurry waved postmedial line. Male genitalia. Uncus broad, slightly expanded at apex, densely suffused with setae laterally, apex truncated. Gnathos strongly sclerotized, beaked. Valva widening from base to apex, apex expanded; sacculus with stick-like sclerotized process in middle, bifurcated at apex. Juxta with two strongly sclerotized lateral lobes joined in apex, apex with minute spines. Phallus cylindrical, curved slightly, with many spinules laterally. Female genitalia. Unknown. Holotype. ♂, Yunnan: Jinghong, 2700 m, 4.VII.1980, gen. slide. no. Ep537 (IZCAS). Distribution. Yunnan. Etymology. The specific name is derived from the Latin "apex" (= apex) and "arcanus" (= closed) in accordance with the lateral lobes of juxta joined distally in the male genitalia.
