Diagnosis. Adult ( Figs. 9–22 View FIGURES 9 – 16 View FIGURES 17 – 22 ). Wingspan 50–57 mm. Head and thorax covered with brown-black hairs, patagia bordered with pale-grey scales; tegulae - with pale-grey and black scales. Forewing color brown-grey; wing pattern with prominent subbasal line, diffused medial shadow, traceable rounded orbicular and traceable reniform usually surrounded with pale diffused area; postmedial fascia dentate, twin with clear white subtornal mark; subterminal area irrorated with grey-fuscous; subterminal line wide, diffused, with characteristic extensions in upper, mid and lower parts of wing; terminal field brown, often with fuscous-grey irroration. Hindwing brown basally, yellow in central part, with wide terminal band, bearing white tornal mark. In male genitalia ( Figs. 46–49 View FIGURES 45 – 47 View FIGURES 48 – 50 , 58– 60 View FIGURES 57 – 66 ) uncus short, massive, spatulated, with small pointed apical extension; tegumen broad, equal to vinculum in length; valva lobe-like with costal flap-like process (developed editum); harpe digitate extending to apex of valva, with serrate inner margin; its shape and arming are is rather variable throuthout the range of the species. Aedeagus rather massive, but short, carina tipped apically; vesica simple, bulbous, bearing moderate basal diverticulum; cornuti absent. Female genitalia ( Fig. 67 View FIGURES 67 – 71 ) figured by Sugi (1976). Papillae anales short, quadrangular; apopyses posteriors and anteriores short, on wide base, equal in length, antrum small, cup-like; ductus bursae somewhat longer and wider then in rotundipennis and becheri , sp. n. corpus bursae sacculate, with small appendix.

Distribution and biology. Occurs in Pakistan, North India, Nepal, Bhutan, Myanmar, Thailand, Vietnam, South East China (provinces Yunnan, Jiangxi, Fujian), Japan (Kyushu, Shikoku), and Indonesia. In Japan, larvae feed on evergreen hard-leaved oak Quercus phylliraeoides , and may cause serious damage in the forest. Moths appear from May to June and from October to November ( Ishihara 1955; Sugi 1976, Miyata et al. 2000). The species occurs widely in South East Asia from Pakistan to Indonesia. In the mainland of Asia it is represented by nominative subspecies, in Indonesia by subspecies Trisuloides sericea hawkeri Prout & Talbot, 1924 and Trisuloides sericea trigonoleuca Prout, 1922 .

Taxonomic note. We did not find significant differences in facies and male genitalia between T. sericea from Borneo, illustrated by Holloway (2009), and specimens from continental Asia. There are not many differences between the male genitalia of hawkeri and trigonoleuca illustrated by Prout (1924), with examined specimens from India, Vietnam and China (taking into account variability in the shape of harpe). Although Holloway (2009) proposed that hawkeri and trigonoleuca night be considered species, we follow the treatment of A.E. Prout (1924) and Sugi (1976) and consider hawkeri and trigonoleuca as subspecies of T. sericea .
