Anabelcia thai sp. n.

( Figs 9, 10, 32)

Type material. Holotype: female, North Thailand, Chiang Mai / Mae Ai Doi Suthep , 1100 m, 3–6.iv.2008, 18˚47’998’’N, 98˚54’8901’’E (leg. T. Ihle) Coll. GBG/ZSM, genit prep. 7414GB ZSM . Paratypes: 1 female, Thailand, Mae Chaem , Chaeson NP, Prov. Lampang 1450 m, 10–11.v.2008, 18˚56’119’’N, 99˚23’481’’E (leg. T. Ihle) ( ABF) ; 1 female, North Thailand ( GRB) .

Diagnosis. The new species is close to A. kala and A. nepalensis , but can be easily separated from them by its bigger size and dark–green with brown colouration of forewing. The scheme of the wing pattern is same as in related species. The female genitalia differ from those of the closest related A. nepalensis by shape of the antrum, the ductus bursae and the sclerotised patch in joining of ductus bursae with corpus bursae. Male of this species is unknown.

Description. Adult ( Figs 9, 10). Wingspan female 46–47 mm. Head and thorax dark mossy-green, tegulae and patagia bordered with black; abdomen greyish with dark-brown crests on segments 1–4. Forewing ground colour dark mossy-green, elements of wing pattern black or brown. Basal field mossy-green, bordered by black twin subbasal line; subbasal field brown, bordered with black subbasal line; medial field mossy-green, bordered with thin dentate antemedial line; orbicular small, pink-brown, bordered with black; reniform black, surrounded with three whitish dots; medial line thin, distinct in costal and ventral parts of wing; subterminal field uninterrupted, brown, with blackish subtornal streak, bordered with brown-green subterminal line; terminal field brown, darker than subterminal, with diffuse blackish streaks between veins; terminal line as row of semilunar black streaks, in ventral part of wing bordered with thin waved white line; cilia brown, greenish opposite veins. Hindwing pale greyish-yellow with traceable discal spot and wide blackish-brown terminal band, bordered with row of dark semilunar streaks surrounded with whitish; cilia brown, greenish opposite veins.

Female genitalia. ( Fig. 32). Most close to A. nepalensis , but all structures somewhat larger. Papillae anales quadrangular, broader than in A. nepalensis ; apophyses anteriores and posteriores almost equal in length, stronger than in A. nepalensis ; antrum like in A. nepalensis but somewhat larger, split for two wide lobes; proximal part of antrum weakly sclerotised, joining with ductus bursae membranous; ductus bursae relatively short, straight, wider than in A. nepalensis ; corpus bursae sclerotised in joining with ductus bursae as a rounded plate, the shape of sclerotised part is different from that of A. nepalensis ; corpus bursae rounded, elongate, larger than in A. nepalensis .

Etymology. The specific name derived from the word “ thai ”, the name of the Thai nation.

Distribution (Map 37). North Thailand, the species is known only from the type localities in Lampang and Chiang Mai provinces in North Thailand.
