Nemoura sichuanensis Li & Yang View in CoL , sp. nov.
( Figs. 21–25 View FIGURES 21 – 25 )
Diagnosis. Epiproct elongate, dorsal sclerite with two darkly sclerotized lateral plates sublaterally, and a downward, wedgeshaped strip crossed by a slanting sclerotized bar. Cercus sclerotized, narrowly elongate, with a sharp apical spine and a bifurcate, subapical hook.
Male. Forewing length 5.8 mm, hindwing length 5.0 mm. Head dark brown; compound eyes dark. Thorax and mouthparts brown. Wings hyaline; legs yellow. Abdomen yellowish brown with pale hairs.
Terminalia ( Figs. 21–25 View FIGURES 21 – 25 ): Tergum nine weakly sclerotized, constricted medially, and with many tiny spines and two long hairs at middle. Sternum nine with slender vesicle; hypoproct rectangular, tapering posteromedially to a slender tip. Tergum 10 mostly sclerotized, with a longitudinal median concavity bearing several tiny, black spines located along anterolateral margin. Cercus sclerotized except membraneous apex, slightly curved medially and narrowing toward tip, with a sharp apical spine and a bifurcate, subapical hook. Epiproct elongate and constricted at middle, its tip emarginate. Dorsal sclerite with two darkly sclerotized sublateral plates and a downward, wedgeshaped strip crossed by a slanting sclerotized bar; ventral sclerite sclerotized, broad at base and narrowing toward apex, lacking spines ventrally. Paraproct with outer lobe distinctly sclerotized to form a papillate projection subapically, adhering to inner lobe; inner lobe slightly sclerotized, broad at proximal half, with a round tip.
Female. Unknown.
Type Material. Holotype: male, CHINA: Sichuan, Luding, Moxi, Yajiageng, 2,100 m, 2005. VI. 19, J. Liu.
Distribution. China (Sichuan).
Etymology. The specific epithet refers to the type locality, Sichuan.
Remarks. The new species is related to N. hangchowensis Chu from Zhejiang because of their elongate epiproct and the similarly sclerotized plates. It may be separated from the latter by the cercus bearing an apical spine and a bifurcate subapical hook and the inner lobe of paraproct round at tip. The epiproct of N. hangchowensis has a slender, large hook in distal half and the outer lobe of the paraproct is characterized by two apical hooks ( Wu 1938).
