详细

An illustrated description of two free-living nematode species, Belbolla gracilis sp. n. and Pseudolella mangrovi sp. n., which were discovered in the sediments of the mangroves in the Yen River Estuary in Vietnam, is provided. Beldolla gracilis sp. n. is similar to B. heptabulba Timm, 1961 and B. warwick Huang, Zhang, 2005 in its oesophagus morphology but it differs from these species in its longer and more slender tail, longer stoma, and longer spicules. Pseudolella mangrovi sp. n. is similar to P. capera Tchesunov, 1978 and P. parva Gagarin, Nguyen Vu Thanh, 2006 in the morphology and the shape of the amphidal fovea, but it is characterized by a shorter body and longer spicules.
