3. Anarsia paraisogona Park & Ponomarenko, 1996

(Figs. 3, 24, 43, 43 a)

Anarsia paraisogona Park & Ponomarenko, 1996: 43; Ponomarenko, 2009: 348. TL: Thailand (North). The holotype is in BMNH.

Diagnosis. Adult (Figs. 3, 24): Wingspan, 11–11.5 mm. The species is superficially similar to A. isogona Meyrick, with a large subtriangular costal patch on the forewing transversally reaching about 3/5 towards dorsum with truncated lower margin, but can be distinguished by having a long expansible hair pencil on underside of the forewing. The male genitalia are quite different from each other as shown in the figures (Figs. 42 and 43). The male genitalia are very similar to those of A. acrotoma Meyrick, but can be distinguished by the right valva with more expanded distal half and more slender ventral process, which is longer than 1/2 the length of the right valva. The hindwing is grayish, with anterior expansion of costa well-developed to beyond middle; the venation is similar to that of A. isogona, with M2 close to M3 basally, M3 and CuA1 connate.

Male genitalia (Figs. 43, 43 a): Uncus relatively long, hook-shaped apically. Tegumen longer than valva, expanded on lateral margin medially, narrower towards apex. Left valve ovate, inflated at base, with membranous flap on surface basally and a strongly curved process arising from near base, with round apex. Right valva relatively narrow, slightly dilated at base and broadened beyond middle, with a long, heavily sclerotized process before middle. Phallus arched, heavily ankylosed with juxta and vinculum at basal 1/4.

Material examined. VIETNAM: 1 ♂, Vinh Phuc Prov., Tam Dao Nat. Park, 9 vii 2003 (KT Park, & Kim), gen. slide no. CIS-6416; 1 ♂, same locality, 30 vii 2006 (Park, Chae, & Cuong); 2 ♂, 1♀, Nhin Binh Prov., Cuc Phuong Park, 750m, 30 vii 2006 (Park, Kim, & Kang), gen. slide no. CIS-6427, -6432.

Distribution. Vietnam (new record; Vinh Phuc Prov.), Thailand (North).

Remarks. In the original description of the species by Park and Ponomarenko (1995), it was erroneously described that the forewing lacks a long hairpencil on the underside of the forewing, but we here confirm that the species has a well-developed hairpencil.
