Theorica valuliae Pinkaew, new species (Lepidoptera: Tortricidae: Olethreutinae), the first record of the genus in Thailand

The genus Theorica Diakonoff, 1966 includes two previously described species that occur in Vietnam (i.e., T.secunda Kuznetsov, 1997) and New Guinea (i.e., T lamyra (Meyrick, 1911)). We report the first occurrence of this genus in Thailand, represented by a new species: Theorica valuliae Pinkaew, n.sp. In addition to illustrations of the adult and genitalia, we also present photographs of living specimens in their natural resting posture.
