(Figs. 18, 20, 39, 39 a, 58, 58a, 66)

Gelechia patulella Walker, 1864: 635 .

Anarsia patulella; Meyrick, 1913: 168; 1925: 153; Caradja & Meyrick, 1935: 69; Park, 1995: 61; Park & Ponomarenko, 1996: 41.

Ananarsia patulella; Ponomarenko, 1997: 52, 2009: 342. TL: Sri Lanka. The type’s depository unknown.

Diagnosis. Wingspan, 9.5–12.0 mm. This species is superficially similar to A. didymopa Meyrick and A. pusillidia sp. nov. by having a small, crescent, blackish costal patch and a similar sized streak beneath it in discal cell. They can be distinguished by the male genital character. The size is considerably variable. The hindwing venation is illustrated in Fig. 20.

Male genitalia (Figs. 58, 58 a): Valvae asymmetrical, more or less similar to each other: left valva narrowed at base, ventral margin convex near middle; numerous palmate scales with long thread-like stalks scattered beyond middle, with a pocket-like membranous flap at basal 1/3 of valva; apex protruded, angled preapically on anterior margin; right valva expanded near base of hind margin, with similar scales. Phallus, short, less than 2/3 the length of tegumen.

Female genitalia (Fig. 66). Ostium funnel-shaped; ductus seminalis arising from junction with corpus bursae. Phallus with a crescent signum.

Material examined. VIETNAM: 3 ♂, 7♀, Cuc Phuong Nat. Park, 200 m, 23 iv 2006 (Park, Kim & Kang), gen. slide no. CIS-6415; 6 ♂, 3♀, Bak Khan Prov., Ba Be Nat. Park, 26–28 vii 2006 (Park, Chae, & Cuong), gen. slide no. CIS-6417; 4 ♂, 3♀, Tam Dao Nat. Park, 450 m, 25 v 2007, gen. slide no. CIS-6418 & -6419, & 6423 (♀); 6♀, same locality, 950 m, 30 vii 2006, gen. slide no. CIS-6421; 8♀, same locality, 24 v 2007 (KT Park).

Host plant. Prunus salicina Lindl.(Rosaceae), Nephelium sp. ( Meliaceae) (Li, 2002).

Distribution. Vietnam (Bac Khan, Nhin Binh, Vinh Phuc Prov.), India, Sri Lanka, China (Yunnan, Kiangsu), Taiwan, Thailand, Australia.

Remarks. This species is widely distributed in the Oriental Region and Australia. Park (1995) indicated that considerable variation was found in the shape of valvae which was considered intraspecific.
