Description	Three new species of Dactylogyrus are described from the gills of the cyprinid fish Balantiocheilos melanopterus (Bleeker) imported from Thailand via the aquarium trade. They are D. coartatus n. sp., D. macrocolpius n. sp. and D. melanopteri n. sp. The double-bar species, D. coartatus n. sp. and D. melanopteri n. sp., are characterised by hooks that are markedly large in relation to the size of the anchors. Clip-like anchors with a sharply recurved, long point are a unique feature of D. coartatus n. sp. The single-bar species, D. macrocolpius n. sp., is characterised by having a copulatory organ composed of a spiral copulum and a medial accessory piece with thorns.
