Pionea nephelistalis Hampson, 1913: 9 .

Nephelobotys nephelistalis (Hampson) : Munroe & Mutuura, 1970: 299.

Diagnosis. Wingspan 25.0–29.0 mm. In appearance, the chocolate brown forewing with the predominantly yellow base, costal and termen bands, dark brown hindwing with yellow termen band and pale yellow vannus ( Fig. 3 ) can be regarded as the most distinct characters for this species in Nephelobotys . In the male genitalia, this species is somewhat similar to N. apiculata sp. nov. in distal protrusion of sacculus with inner angle extending into a process, but can be distinguished by costal margin of valva without a process, ventral process of transtilla developed and thick, outside sella with pointed and excurved ventral process, distal protrusion of sacculus with dorsal margin thickly bearing spines and inner angle extending into a stout process ( Fig. 13 ). In the female genitalia, the well sclerotized, inversely trapezoidal antrum with posteroventral margin straight, and ductus bursae with a sclerite near seminalis ductus ( Fig. 20 ) can separate N. nephelistalis from all other species in the genus.
