Description
Summary:Three new species belonging to the genera Diplolaimella and Thalassomonhystera of the family Monhysteridae and Theristus of the family Xyalidae are described from shrimp culture ponds near mangrove zones of Khung Kraben Bay, Thailand. Diplolaimella thailandica sp. n. resembles D. dievengatensis but differs from it by features of the ratios b and V, and size of the spicules and tail of the male. Thalassomonhystera siamensis sp. n. resembles T. diplops but differs from it in features of the amphids, ocelli, cloaca and gubernaculum. Theristus (Penzancia) longisetifer sp. n. resembles T. flevensis, T. ambronensis, T. macroflevensis, and T. pratti but differs from them in features of the cervical setae, ventral supplement of the male and others.
