Abstract
Two new species of caddisflies, Macrostemum nigralatum n. sp. and Anisocentropus tairomyenensis n. sp., are described and figured from lower-hill evergreen forests in southern Thailand. Wings of M. nigralatum are black, which distinguishes the new species from other related species. Anisocentropus tairomyenensis n. sp. is a member of the subgenus Anisomontropus and is characterized by the obvious basal expansion of the preanal appendages.
