description: Indonemoura baishanzuensis Li & Yang, sp. nov.
(Figs. 1–7)
Diagnosis. Tergum 9 distinctly constricted medially. Epiproct nearly parallel­sided in dorsal view, with distinct apical incision; ventral sclerite expanded ventrally into a large semicircular ridge narrowing apically. Outer lobe of paraproct strongly sclerotized with apical spines curved inward apically, of which the inner spine is forked but the outer spine is single and curved inward apically.
Male: Forewing length 7.5–8.4 mm, hindwing 6.5–6.8 mm. Head (Fig. 7) and mouthparts brown; compound eyes dark. Antennae, thorax including pronotum (Fig. 7), and legs brownish yellow; wings hyaline. Abdomen, hypoproct, and cerci yellow; hairs on abdomen mostly pale.
Terminalia. (Figs. 1–6): Tergum 9 weakly sclerotized, distinctly constricted medially, with distinct mid­anterior incision and small mid­posterior incision, and with two groups of tiny spines at middle. Sternum 9 with slender vesicle; hypoproct rather wide basally, then distinctly tapering toward tip, without tiny spines apically. Tergum 10 mostly weakly sclerotized except distinctly sclerotized bands obliquely across each side of the tergum, with a rather deep median concavity, and with two groups of tiny spines along anterolateral margin of the concavity. Cercus membranous, longer than wide, slightly curved inward apically. Epiproct nearly parallel in dorsal view, with distinct apical incision, with ventral sclerite strongly sclerotized, broad at base and becoming narrower toward apex, expanded ventrally into a very large semicircular ridge narrowing apically and bearing row of distinct spines. Paraproct divided into three lobes: inner lobe pointed, distinctly sclerotized, adhering to large median lobe; median lobe mostly sclerotized, well developed, with a broad proximal rectangular lobe and an adjacent papillate lobe; outer lobe strongly sclerotized, distinctly recurved at middle, with apical spines curved inward, of which the inner spine is forked but the outer spine is single and curved inward apically.
Female: Unknown.
Type material. Holotype: male, CHINA: Zhejiang, Qingyuan, Baishanzu Mountain, 1,500 m, 1994. V.18, H. Wu. Paratypes: 1 male, CHINA: Fujian, Wuyi Mountain, Sangang, 750 m, 2004. V.9, X. Liu; 1 male, CHINA: Zhejiang, Yuyao, Siming Mountain, 1960. IV. 29, C. Yang.
Distribution. China (Zhejiang, Fujian).
Etymology. The species is named after its type locality.
Remarks. The new species is similar to I. fujianensis from Fujian, but may be separated from the latter by the following features: median lobe with a broad proximal rectangular lobe and an adjacent papillate lobe; apical spines of outer lobe with its proximal apical spine forked but outer spine single and curved inward apically. In fujianensis, the median lobe of the paraproct is narrow and has no sclerotized lobes; apical spines of the outer lobe has its proximal spine single but the outer spine furcated (Li & Yang 2005).
