( Figs. 2 View FIGURES 1 – 21 , 23 View FIGURES 22 – 40 , 42, 42 View FIGURES 41 – 43 a a –b)

Anarsia isogona Meyrick, 1913: 169   ; Meyrick, 1925: 153; Caradja & Meyrick, 1935: 69; Clark, 1969: 245; Park, 1995: 60; Ueda, 1997: 79.

Ananarsia isogona   ; Ponomarenko, 1997: 52, 2009: 341. TL: India, Nilgiris. The holotype in BMNH.

Diagnosis. Adult ( Figs. 2 View FIGURES 1 – 21 , 23 View FIGURES 22 – 40 ): Wingspan, 10.5–11.0 mm. The species is superficially similar to the following species, A. paraisogona Park & Ponomarenko, 1995   , with the elongated forewing and having a large subtriangular costal patch medially, but can be distinguished by the lack of a long hair pencil on the underside of the forewing. The hindwing is grayish with the anterior expansion developed to beyond middle, and the venation with M 2 close to M 3 basally, M 3 and CuA 1 connate and with acute apex. The male genitalia also have quite different characteristics: such as different shapes of valvae, especially the long-stalked, palmately modified scales

Male genitalia ( Figs. 42, 42 View FIGURES 41 – 43 a a): Abdominal sternite VIII rounded on caudal margin, with long hair pencils laterally. Uncus rather short; socius semiovate. Tegumen about as long as valva, slightly expanded laterally beyond middle. Left valve broad in basal 3 / 5, outer margin abruptly truncated, then very narrowed, tapered; basal process slender, curved, tapered, acute apically; patch of long-stalked palmately modified scales occupying in distal half. Right valve more or less similar to left one, but ventral margin gently rounded, with a very small basal process. Phallus slender, tapered, about 2 / 3 the length of left valva.

Material examined. VIETNAM: 1 ♂, Vinh Phuc Prov., Tam Dao Nat. Park, 750m, 30 vii 2006 (Park, Chae, & Cuong), gen. slide no. CIS- 6434; 1 ♂, same locality, 450 m, 15 viii 2006 (KT Park, MY Kim, & MY Chae).

Host plant. Schima   sp. ( Theaceae   ) ( Sakamaki, 2013).

Distribution. India, China ( Taiwan: Taoyuan Co.) Vietnam (new record; Vinh Phuc Prov.), Japan.

Remarks. Slight morphological differences in male genitalia are found between Taiwan ( Fig. 42 View FIGURES 41 – 43 a b) and Japan specimens: Vietnam specimen has the ventral margin of valva strongly angled beyond middle and the abdominal sternite VIII rounded on caudal margin, not concave at middle. The Vietnam specimens are tentatively treated as conspecific in this paper. However, these differences should be re-examined in detail when additional material is available.
