Diagnosis. Length of forewing is 9.5–11 mm in males and 12.5–13 mm in females. Nephelomilta angkorensis is similar externally to N. sumatrana effractoida ssp. nov ., N. klapperichi , N. fangae sp. nov. and N. pusilla , but can be distinguished from them by the medial line V-like curved on the vein 1A; the similar shape of the medial line is also characteristic for N. hortensis hortensis sp. nov. and N. hortensis fansipana ssp. nov ., but N. angkorensis differs from the nominate subspecies of N. hortensis sp. nov. in the narrower posterior section of the medial line and the slightly paler hindwings, and from N. hortensis fansipana ssp. nov . it differs in its more reddish pattern and also the narrower posterior section of the medial line. In many cases a reliable identification of N. angkorensis is possible only by the genitalia structure. The male genitalia of N. angkorensis are very similar to those of N. pusilla , but differ in the longer apical costal lobe, the significantly smaller distal membranous lobe of the valve, the slightly smaller ventral-apical costal process, the larger ampulla, the significantly smaller area of the basal dentation of the costa, the slightly larger subapical saccular process, the larger and more heavily sclerotized carinal plate of the aedeagus with the much larger distal thorn, the significantly broader medial diverticulum with the larger spines on its tip, the smaller distal diverticulum with the narrower cluster of spines, which are thinner than those in N. pusilla . The female genitalia of N. angkorensis are similar to those of N. pusilla , but differ in the shorter and slightly broader antevaginal plate, the asymmetric lateral margins of the ostium bursae, and the slightly smaller appendix bursae.
