Description of the female

(Fig. 9). Forewing length 6.5-7.2 mm; coloration similar to male. Sternum VII membranous, lacks pregenital plate. Sternum VIII with wide, entirely brown subgenital plate covering more than two third of length and slightly overhanging, its width is less than two thirds of segment’s width; paired paragenital plate relatively large but indistinct, rounded triangular, weakly attached to lateral sides of the subgenital plate. Posterior margin of the subgenital plate laterally rounded and medially slightly concave. Sternum IX lightly sclerotised, anterior margin overlapped by the subgenital plate. Sternum X and paraproct typical. Inner genitalia mostly membranous, with two small lateral sclerites attached to the anterolateral edges of the subgenital plate, and a medium sized, bulbous structure beneath spermathecal ductus, involving a central sclerite ring; genital opening narrow.

Material examined.

China: Guangxi Zhuang Autonomous Region, Wuming County, Liangjiang Town, Neichao, Neichao River above Neichao Ming Hotel, 220 m, 23°29.664'N, 108°21.622'E, 2015.VII.24, leg. JN Li, S Li, WH Li, D Murányi: 1 male and 3 females (HNHM); the same locality, 230 m, 23°29.457'N, 108°21.600'E, 2017.Ⅶ.13, leg. RR Mo, Y Lai: 1 male (HIST); China: Guangxi, Laibin City, Jinxiu County, Dayaoshan National Nature Reserve, Yinshan Park, 1210 m, 24°16.133'N, 110°36.924'E, 2012.IV.8. Leg. WH Li: 1 male (HIST).

Distribution.

China (Fujian, Guangdong, and Guangxi).

Ecology.

In Guangxi, the species was found in a large, rocky stream by the foothills of the Damingshan (Fig. 10d). Other adult stoneflies collected at the locality are Rhopalopsole sinensis Yang & Yang, 1993 and a yet undescribed Amphinemura sp. Not any Euholognatha larvae were found, but several larvae and exuviae of Perlidae ( Agnetina sp., Neoperla sp., Togoperla sp.). All the I. scalprata specimens were fully coloured, indicating that emergence period was past its peak.

Remarks.

The female of I. scalprata is less distinctive, similar to the female of I. quadrispina as described above.
