Abstract. Two new species of the family Gelechiidae, Conciibina trigonalis Park
and Ponomarenko, n. sp. and Teleiodes gangwonensis Park and Ponomarenko, n. sp.
are described from Korea. Telphiisa ewyzeucta Meyrick, 1922, is transferred to
Concubina: Concubina ewyzeucta (Meyrick 1922), n. comb. Concubina subita N.
Omelko and M. Omelko, 2004 is considered a new junior synonym of C. euryzeucta.
