He Zhiqiang; Yunnan Prov.: 12 females, Menglun Town, 640m, 21–30.IV.1974, coll. Zhou Yao, Yuan Feng & Hu Yinyue; 1 male, Zhenkang County, Nansan Town, 09.V.2011, coll. Lu Lin, at light; 1 male, Mengla County, Bubang Village, 690m, 19.V.2011, coll. Lu Lin; 3 males, Menghai County, Daluo Town, 679m, 22.V.2011, coll. Lu Lin, at light.

Remarks. A description of this species was given by Ghauri (1971). Some variation is found as follows. Crown always without black band, but black markings of forewing vary (Plate V: A–H). Pygofer side usually distodorsal and distoventral corner round, spine 1 long, slim; other spines usually 4 in number, short, but variation is found ( Figs. 17 A–E); apophysis of style always elongate, but its shape varies ( Figs. 18 A–C). This is the most easily distinguished Nephotettix sp. The most important feature is the completely unmarked crown with a distinct furrow (Plate V: A–H).
