Material examined. China: Hainan Prov.: 1 male, Jianfengling, 18.V.1983, coll. Zhang Yalin; 1 male, 2 females, Bawangling, 25.V.1983, coll. Zhang Yalin, at light; 2 females, Bawangling, 28.V.1983, coll. Zhang Yalin; Yunnan Prov.: 2 males, 10 females, Xishuangbanna, Menghai County, 21–30. IV.1974, coll. Zhou Yao, Yuan Feng & Hu Yinyue; 1 male, Jinghong Town, Jinghong County, 30.VIII.2010, coll. Han Juan, at light; 3 males, Yingjiang County, Zhina Town, 1086m, 03.VI.2011, coll. Lu Lin, at light.

Remarks. An adequate description of this species was given by Ghauri (1971) but some variation occurs as follows. Crown always with submarginal black transverse band but black markings of forewing vary (Plate IV: A– B, D–F). Although closely resembling N. nigropictus in general coloration, males of N. parvus may be distinguished by the distinctive aedeagus ( Figs. 16 G–H) and females by the almost pointed crown (Plate IV: D–F).
