Abstract

Eublemma amabilis Moore [1884] (Erebidae) and Syncola pulverea (Meyrick, 1907) (Blastobasidae) are the dominant predators of cultured lac, Kerria lacca (Hemiptera: Kerridae), in northern Thailand. Two additional gelechioid species, Scythropiodes lacca Adamski, n. sp. (Depressariidae: Oditinae), and Stathmopoda venustaMeyrick, 1913 (Stathmopodidae) are, to a lesser degree, also predatory on lac insects. Several species of detritivorous Lepidoptera are found on lac-infested branches of Samanea saman (Jacq.) Merr. (Fabaceae) including: Erechthias leucopogon (Meyrick, 1924) (Tineidae), Stenachroia elongellaHampson, 1898 (Pyralidae: Galleriinae), Cryptoblades gnidiella (Milliere, 1867) (Pyralidae: Phycitinae), and Pyroderces spatulata Adamski, n. sp. (Cosmopterigidae). Adults of all species associated with lac are described or redescribed. Detailed descriptions of available immature stages of these lac-associated moth species are supplemented with chaetotaxal maps, illustrations, photographs, and scanning electron micrographs. A lectotype is designated for Blastobasis pulvereaMeyrick, 1907.
