(Figs. 1, 22, 22 a, 41, 41a–b, 60)

Anarsia tricornis Meyrick, 1913: 168; Meyrick, 1925: 153; Clarke, 1969: 250; Park, 1995: 64; Park & Ponomarenko,1996: 41. Ananarsia tricornis Ponomarenko, 1997: 53, 2009: 343. Type locality (TL): Sri Lanka, Maskeliya. The type in BMNH.

Diagnosis. Adult (Figs. 1, 22): Wingspan, 10.5–13.0 mm. The species is superficially similar to A. anisodonta Diakonoff, 1954, which was described from Papua, Indonesia, with a large, unique, triangular costal patch on forewing, but can be distinguished by the male genitalia with shorter tegumen and the morphological characteristics of the valvae: right valva broad and shorter than that of A. anisodonta, with basal hook-shaped process strongly angled, shorter; left valva broadly expanded ventrally beyond middle, the patch of the modified scales broader than that of A. anisodonta. There is no hairpencil on the underside of the forewings.

Male genitalia (Figs. 41, 41 a–b): Uncus large, broadened medially, exceeding apices of socius. Valvae asymmetrical: left valva with a strongly curved process arising from near base of ventral margin, reaching about half of valva; right valva similar to left one, but the basal 2/5 narrow, then ventral margin expanded, and ventral process absent. Phallus strongly curved, lanceolate, with a short, inwardly directed lobe near base.

Female genitalia (Fig. 60): Apophyses anteriores very short, about 1/5 the length of apophyses posteriors. Abdominal segment VII with a pocket-like membranous flap medially. Ostium bursae deeply concave on caudal margin, cup-shaped. Ductus bursae narrow, as long as corpus bursae. Signum small, crescentic.

Material examined. CAMBODIA: 3 ♂, Seima, 12o14′11″ N 107o02′ 35″E, 9 xi 2011 (YS Bae, YK Kim, YD Ju, BS Park, & HJ Lee), gen. slide no. CIS-6401 & -6402; 1♀, same locality, 12o16′37″ N 107o03′ 57″E, 9 xi 2011 (YS Bae, YK Kim, YD Ju, BS Park, & HJ Lee), gen. slide no. CIS-6404; 1 ♂, 1♀, same locality, 12o14′11″ N 107o02′ 35″E, 16 viii 2013 (YS Bae, YK Kim, YD Ju, BS Park, & HJ Lee), gen. slide no. CIS-6403; 1♀, Kirirom, 11o19′8″ N 104o02′ 6″E, 6 xi 2014 (YS Bae et al.). VIETNAM: 1♀, Cuc Phuong Nat. Park, 450 m, 24 iv 2006 (Park, Kim & Kang), gen. slide no. CIS-6412; 1 ♂, Tam Dao Nat. Park, 25 v 2007 (KT Park), gen. slide no. CIS-6413.

Distribution. Cambodia (new record; Seima), Vietnam (new record; Vinh Phuc Prov., Nhin Binh Prov.), Sri Lanka, Indonesia (Sulawesi), Indonesia.

Remarks. The species was described from Sri Lanka, based on a single male, and also known in Indonesia (Sumatra and N Sulawesi), and Taiwan (Park, 1995). A minor difference was found in the shape of the hookshaped basal process near base of the ventral margin of the left valve, but considered as an individual or geographical variation.
