Diagnosis. Length of forewing is 11.5–13 mm in males and 15.5–16 mm in females. This and the next three species (N. fangae sp. nov., N. angkorensis and N. pusilla) form a complex of the closely related taxa (so called ‘ N. pusilla species-complex’), with the male genitalia characterized by the valve slightly narrowed distally, the short and broad apical costal lobe, the large trigonal ampulla, and the large aedeagus and its vesica (compared to the genital capsule). Nephelomilta karenkonis is one of the unmistakable species of the genus, which can be easily distinguished from other red patterned species by its thin antemedial transverse line, which is strongly V-like curved in the cell, the thin postmedial line, and the broad area between the medial and postmedial lines. The male genitalia of N. karenkonis are most similar to those of N. fangae sp. nov. due to the absence of a basal dentation of the costa, but differ by the larger apical lobes of the juxta, the slightly narrower valve with the more strongly prominent medial costal angle, the apical costal lobe slightly narrower and more prominent, the ventral costal plate significantly narrower and almost straight, the much smaller ampulla, the slightly shorter subapical saccular process, the more numerous spines on the distal diverticulum of the aedeagus vesica, and the larger and more numerous spines on the tip of the medial diverticulum. The female genitalia of N. karenkonis differ clearly from those of N. fangae sp. nov. in the shorter and narrower antevaginal plate, the ostium bursae margin smoothly
arcuate (whereas in N. fangae sp. nov. it has the deep V-like ventral concavity), the larger appendix bursae, and the narrower cluster of spines in the medial section of the corpus bursae.
Distribution. Endemic of Taiwan Island.
