Remark. In the original description, Wileman (1910) mentions two specimens, a male with the date “ April 22nd, 1906 ” and a female with the date “ May 2nd, 1907 ”, which should be treated as syntypes. We did not find the female specimen in the NHMUK collection. Therefore, to avoid any confusion with N. karenkonis , here we designate the male syntype as the lectotype.

Diagnosis. The species significantly varies in size: the length of forewing is 9–11 mm in males and 13–13.5 mm in females. Nephelomilta pusilla is most similar externally to N. fangae sp. nov., and can be distinguished from it only by the genitalia structure (see the diagnosis of N. fangae sp. nov.). The male genitalia of N. pusilla are very similar to those of N. angkorensis , but differ in the shorter apical costal lobe, the significantly larger distal membranous lobe of the valve, the slightly larger ventral-apical costal process, the significantly larger area of the basal dentation of the costa, the smaller ampulla, the slightly smaller subapical saccular process, the narrower and more weakly sclerotized carinal plate of the aedeagus with the smaller thorns, the significantly broader distal diverticulum with the broader cluster of spines, which are more robust than those in N. angkorensis , and the narrower medial diverticulum with the smaller spines on its tip. The female genitalia of N. pusilla are similar to those of N. angkorensis , but differ in the antevaginal plate slightly longer, narrower, and more heavily sclerotized, the symmetric lateral margins of the ostium bursae, and the slightly broader appendix bursae.

Distribution. Endemic to Taiwan Island.
