Diagnosis and notes. Owada (1982) recorded two male moths collected in Amami-oshima Island, Ryukyus, under the name Herminia terminalis . In a revision of Japanese Herminiinae, Owada (1987) enumerated collection data of H. terminalis from Japan , Taiwan , Nepal and South India , with illustrations of the male genitalia from Amami-oshima Is. and the female genitalia from Taiwan . In the present study, judging from the structure of the male labial palpi ( Figs 1, 3 ), it is doubtless that the Japanese population of the decipiens complex is a bona species. The sickle shaped labial palpus represents the ground plan of the subfamily Herminiinae . The male short costal projection and the female ductus bursae are also clear diagnostic features. The basal ornamentation of the aedeagus vesica of H. amamioshima is very similar to that of H. terminalis , but the basal short conical cornuti are a little smaller. Description. Male ( Fig. 11 ). Expanse: 20–24 mm ; length of forewing: 10–13 mm .Antenna ciliate. Labial palpus sickle-shaped, upturned ( Figs 1, 3 ), third segment long, ca. 1/2 of second segment. Foreleg ( Owada 1987 , fig. 206) heavily tufted with hairs; coxa elongate; trochanter a little elongate; femur a little longer than coxa; tibial sheath large, longer than femur; tarsus reduced to one segment, very short. Forewing brownish grey, transverse lines dark brown, antemedial line slightly dentate, oblique from costa, angulate in cell, median shade dark brown, distinct under reniform stigma, postmedial line irregularly dentate, excurved from costa to M 3 , concave inwardly at M 1 , subterminal line faint, represented by dark brown shade, irregularly sinuate; medial and terminal areas of forewing broadly shaded by dark brown in fresh specimens. Hindwing paler, subterminal line pale ochre, faint, edged internally with dark brown. Female ( Fig. 12 ). Expanse: 21–24 mm ; length of forewing: 11–12 mm . Labial palpus sickle shaped, foreleg not modified, wing pattern same as in male. Male genitalia ( Figs 21 , 25–26 ). Uncus falciform, curved, with pointed apex. Vinculum wide V–shaped. In valva, sclerotized costa straight, ended in an acute pointed projection. Aedeagus slightly curved, everted vesica with a mass of short conical cornuti in basal portion, finely scobinate in apical portion. Coecum penis small. Female genitalia ( Fig. 40 ). Papillae anales and 8th segment rather broad. Ductus bursae sclerotized, straight, rather wide in ostium, the gradually narrowed, tightened in base. Cervix bursae furrowed, with many minute spines, corpus bursae about twice as large as cervix bursae, with larger spines in caudal half and minute spines in bottom. Distribution. Japan : Amami-oshima Is., Shimo-Koshikijima Is., Kyushu ( Kagoshima ). Etymology. Named after the type locality, noun in apposition.
