Diagnosis. This species can be clearly distinguished from H. amamioshima by the male labial palpus, of which second segment is long and straight, directed forwards, and the third segment is shorter (Figs 1–4). The basal ornamentation of the aedeagus vesica of this species is a little variable, but slightly different from that of H. amami- oshima (Figs 21, 25–26), i.e. short conical cornuti at basal portion are a little larger (Figs 22, 27–28). Shape of uncus and length of costal process are rather variable. In H. terminalis, the ostium of ductus bursae is contracted (Fig. 41), while it is widened in H. amamioshima (Fig. 40). On the other hand, the basal potion of ductus bursae is widened in H. terminalis, while it is rather constricted in H. amamioshima .

Description. Male (Fig. 13) & female (Fig. 14). Expanse, 20–27 mm; length of forewing, 10–14 mm. Male labial palpus (Figs 2, 4) long, second segment straight, directed forwards, third segment shorter than that of H. amamioshima, ca. 1/3 of second segment. Male foreleg and wing maculation as in H. amamioshima . Male genitalia (Fig. 22, 27–28). Similar to those of H. amamioshima . Apical costal process of valva longer. In basal portion of everted vesica, cornuti a little larger. Coecum penis small. Female genitalia (Fig. 41). Papillae anales and 8th segment as in H. amamioshima . Ductus bursae sclerotized, a little curved, contracted at ostium, broadened in basal portion. Cervix and corpus bursae as in H. amamioshima .

Distribution. Endemic to Taiwan.
