Three new species of free-living nematodes of the family Comesomatidae from the delta of the Mekong River, Vietnam (Nematoda, Monhysterida)

V.G. Gagarin & Vu Thanh Nguyen

Abstract. Sabatieria parvula sp. n., Dorylaimopsis tumida sp. n. and Paracomesoma curvatum sp. n. from the delta of the Mekong River (Vietnam) are described and illustrated. Sabatieria parvula sp. n. differs from S. parabyssalis Wieser, 1954 and S. stekhoveni Vitiello, 1970 in the slenderer body, longer tail and narrowed labial region. Dorylaimopsis tumida sp. n. differs from D. mediterranea Grimaldi de Zio, 1968 in the shorter body, longer cephalic setae, shorter spicules and absence of striation of spicules. Paracomesoma curvatum sp. n. differs from P. longispiculum (Timm, 1961) in the longer body, shorter cephalic setae, longer stoma and spicules, and structure of cuticle areolation.
