Diagnosis. The male labial palpus of this species is same as in H. decipiens (Figs 5, 6). The basal ornamentation of everted vesica is not so variable, and two large conical cornuti are present. The coecum penis of Himalayan H. yuksam (Fig. 24) is distinctly larger than those of H. decipiens, H. terminalis and H. amamioshima (Figs. 21, 22, 23). In the female genitalia, the anterior portion of the ductus bursae is wider and has not a small round tubercle (Fig. 43), which is found in H. decipiens (Figs 42, 45–50).

Description. Male (Fig. 18) & female (Fig. 19). Expanse 22–27 mm; length of forewing 12–13 mm. Male labial palpi (Fig. 6) similar to those of H. decipiens (Fig. 5). Male foreleg and male and female wings as in the other species of this complex. Male genitalia (Fig. 24, 38–39). Similar to those in H. terminalis, costal apical process a little longer. Coecum penis distinctly larger. Two large short conical cornuti at base of everted vesica (Figs 38–39). Female genitalia (Fig. 43). Papillae anales and 8th segment as in H. amamioshima and H. decipiens . Ductus bursae sclerotized, slightly curved, narrow in ostium, gradually broadened towards basal portion, without a small round protuberance found in H. decipiens . Cervix and corpus bursae as in H. amamioshima and H. decipiens .

Distribution. India (Sikkim), East Nepal.
