Li, Weihai & Yang, Ding, 2005, Two new species of Indonemoura (Plecoptera: Nemouridae) from Fujian, China, Zootaxa 1001 (1), pp. 59-63 : 60-61

Indonemoura fujianensis Li & Yang , sp. nov.

( Figs. 1–5 )

Diagnosis. Tergum 10 distinctly constricted medially. Epiproct with small apical incision and ventral sclerite expanded ventrally into a large semicircular ridge. Outer lobe of paraproct strongly sclerotized, apically with two slender spines.

Male. Body length 4.2 mm; forewing length 6.7 mm, hindwing length 5.5 mm. Head, compound eyes, antennae, and mouthparts dark brown. Thorax brown. Wings hyaline. Legs brownish. Abdomen yellowish with pale hairs.

Terminalia ( Figs. 1–5 ): Terga 9 and 10 weakly sclerotized, with two groups of tiny spines and hairs at mid­posterior margin respectively. Sternum 9 with claviform vesicle; hypoproct wide basally, then gradually tapering toward tip. Tergum 10 constricted medially, with large mid­posterior incision, hind margin mostly sclerotized. Cercus slightly sclerotized, longer than wide. Epiproct long, recurved, dorsal sclerite with a small incision, with ventral sclerite strongly sclerotized, broad at base and becoming narrower toward apex, expanded ventrally into a large semicircular ridge with black spines. Paraproct divided into three lobes: outer lobe distinctly sclerotized and curved inward, apically with two slender spines, outer spine of left outer lobe bifurcated apically while of the right one not; median lobe slightly sclerotized, basally broad and tapering toward apex; inner lobe sclerotized and curved upward, about as long as outer and median lobes, with pointed tip.

Female. Unknown.

Type Material. Holotype 1 male, CHINA: Fujian, Meiluowan , 1980. XI. 14, F. Jiang.

Distribution. China (Fujian).

Etymology. The species is named after its type locality, Fujian.

Remarks. The new species is similar to Indonemoura hubeiensis , but may be separated from the latter by the following features: terga 9 and 10 each with two groups of tiny spines at mid­posterior margin; outer lobe of paraproct rather wide apically with two long curved spines, of which the outer spine of the left outer lobe is forked; inner lobe of paraproct curved upward and triangular. In I. hubeiensis , terga 9 and 10 have no tiny spines, the outer lobe of the paraproct is rather narrow apically with a single long straight spine bearing 2 weak subapical spines.
