Indonemoura wangae sp. nov.

(Figs. 1–3)

Adult habitus. General color dark brown. Head dark brown; mouthparts brown but palpi brownish; antennae brown; compound eyes black. Thorax dark brown. Pronotum dark with paler anterolateral corners, generally rectangular but anterior margin slightly convex, much longer than wide. Legs mostly dark brown, with lighter tarsi, femora lacking band; wings membrane brownish, with darker veins. Abdominal segments mostly brownish but terminalia darker, covered with brown clothing hairs.

Male (Figs. 1–3). Forewing length ca. 9.3 mm, hindwing length ca. 8.3 mm. Tergum 9 (Figs. 1a, 3a) with distinctly sclerotized anterior margin, with a small weakly sclerotized mid-posterior area, mid-posterior portion lacks long setae and bears tiny spines. Sternum 9 (Figs. 1b, 3b) basomedially with claviform vesicle, constricted basally and enlarged subapically; hypoproct basally wide and nearly quadrate, medially gradually tapering towards tip where several short stout spines are covered. Tergum 10 (Figs. 1a, 3a) mostly sclerotized except for narrow longitudinal concavity beneath epiproct, the concavity widened anteriorly and anterolaterally bearing many black spinules. Cercus slightly sclerotized, ca. 2x as long as basal width. Epiproct (Figs. 1a, 1 c–d, 2b, 3a, 3c) nearly parallel-sided with narrower apex in dorsal view, apex with a narrow median incision; ventral sclerite strongly sclerotized, broad at base and medially getting narrower, expanded ventrally into semicircular ridge with rows of black spines, the ridge nearly rounded in outline but with shallow posterior notch (Fig. 1d). Paraproct typical of the complex (Figs. 1a, 1b, 1d, 2a, 3 a–3b, 3d): slender inner lobe sclerotized and adhering to median lobe; median lobe sclerotized, basally broad and then tapering toward a bilobed apex; outer lobe darkly sclerotized, much longer than median lobe, with an out-curved, finger-like apical prong and an inward and upward directed subapical tooth.

Female. Unknown.

Type material. Holotype male (CAU): China: Hubei Province, Shennongjia National Natural Reserve, Guanmenshan, 2007.VII.19, light trap, F. Wang.

Etymology. The species is named after the collector of the holotype, Ms. Fang Wang.

Distribution. It is known only from the type locality in Hubei Province of Central China, and it is the second Indonemoura to be known from the province nearly thirty years after the description of I. hubeiensis Yang & Yang, 1991.

Remarks. The new species seems most similar to I. yangi Li & Yang, 2006 from Guangxi, in having similar inner and median lobes of paraproct, and similar spinous apex of hypoproct, but it can be easily separated from I. yangi by the apex of outer paraproctal lobe which has a slender outer prong and a short inner subapical tooth. In I. yangi, the outer lobe of paraproct only has 2–3 similar sized apical spines and lacks a subapical tooth (Li & Yang 2006). Additionally, I. wangae has a nearly parallel-sided epiproct in dorsal view whereas the epiproct of I. yangi is swollen medially.
