Abstract
Two species of Phycitinae, Rabiria rufimaculella ( Yamanaka, 1993 ) and Copamyntis martimella Kirpichnikova & Yamanaka, 2002 , are reported for the first time from Korea. Rabiria rufimaculella can be recognized by having two reddish-yellow and short bands near the postmedial and antemedial line, and by the bifurcate gnathos and the cornutus which is formed by numerous thorn-shaped sclerites in male genitalia. Copamyntis martimella can be distinguished with the congeners by the uniformly distributed setae on the sacculus and the curved aedeagus in male genitalia and the peanut-shaped signum near the middle of the corpus bursae in female genitalia. The adults and genitalia of the species are redescribed and illustrated.

INTRODUCTION
The Phycitinae are one of the largest subfamilies of the family Pyralidae in Lepidoptera, comprising approximately 5,000 species in the world ( Li and Ren, 2009 ). Leech and South (1901) first reported 3 species of Phycitini from the Korean Peninsula; Okamoto (1924) , Shibuya (1927) , Park and Lee (1958) , Park (1976 , 1983 , 1993) , Byun et al. (1997) , Choi et al. (1998 , 1999) , Paek et al. (1999 , 2002) , Paek and Bae (1999 , 2000 , 2001a , 2001b) , and Byun and Lee (2008) , respectively, made contributions to the faunal study of Korean Phycitinae. Currently, Bae et al. (2008) reviewed the subfamily with 79 known species from South Korea. In the present study, the authors add two more Phycitinae species for the fauna of Korea: Rabiria rufimaculella ( Yamanaka, 1993 ) and Copamyntis martimella Kirpichnikova & Yamanaka, 2002 . The morphology of adults and genitalia of the species are redescribed and illustrated. The specimens examined are deposited in Incheon National University (UIK/UIB) and Korea National Arboretum (KNAE) respectively. Abbreviations used herein are as follows: TS, type species; TL, type locality; GW, Gangwon; GG, Gyeonggi.

Diagnosis . There is no species similar to R. rufimaculella , and it can be easily recognized by the unique wing pattern and the genitalia characters as follows: the antemedial line is bordered by reddish-yellow band distally; inner side of postmedial line with short reddish-yellow spot distally. In male genitalia, the gnathos is bifurcate, and the cornutus is formed by numerous thorn-shaped sclerites in aedeagus.
Adult ( Fig. 1A ). Wingspan 15-18 mm. Frons pale grayish-brown; labial palpus fuscous and upturned, 2nd and 3rd segment same length, inner side with white scales; maxillary palpus grayish-white, about 1/3 length of 3rd segment of labial palpus; proboscis covered with white scales; antenna fuscous, scape enlarged, dorsal part grayish-white. Thorax, patagium and tegula grayish-brown. Forelegs with femur white, tibia and tarsus fuscous; midlegs with femur and tibia white, mixed with brown, tarsus pale brown; hindlegs with femur and tibia white, mixed with brownish-gray scales, tarsus pale brown, inner side and tip with pale gray scales. Forewing with ground color brownish-gray; antemedial line grayish-white, straight, oblique outwardly from 1/3 of costa, bordered distally by broad reddish-yellow band; postmedial line grayish-white, sinuous, inside distally bordered by short reddish-brown spots; median area with grayish scales near costal area; distal discoidal spots two, fuscous; terminal grayish- white, interneural spots black, subterminal area suffused with gray scales; fringe pale grayish-brown. Hindwing pale gray, terminal line and fringe pale brown.
Male genitalia ( Fig. 2A ). Uncus semicircular; gnathos bifurcate apically, each arm finger-shaped, slightly longer than uncus, rounded in the end; transtilla connected as rectangular, terminal margin rather flat; valva rounded at apex, costa enlarged as triangular; sacculus about 2/3 length of valva; juxta U-shaped, lateral lobes as long as gnathos; vinculum rather short; saccus rounded; aedeagus short, about 1/2 length of valva, narrow at apex, cornutus formed by numerous thornshaped sclerites.
