Abstract

An illustrated description of two free-living nematode species—Leptolaimoides brevicaudatus sp. n. and Paramonhystera affinis sp. n.—from the water bodies of Vietnam is presented. L. brevicaudatus is similar to L. thermastris (Lorenzen, 1966); L. gangioensis Hoang Lai-Phu et al., 2009; and L. asiaticus Gagarin, Nguyen Vu Thanh, 2005 in regards to body size, but differs from these species by a shorter and less slender body, longer spicules, and the absence of precloacal supplements in males. Paramonhystera affinis sp. n. is morphologically similar to P. parabutschlii (Timm, 1961) and P. levicula (Lorenzen, 1972), but it has shorter and sparse somatic setae, six outer labial setae (versus four outer labial setae in both compared species), and shorter spicules.

越南的两种新生活线虫（线虫）的描述

摘要

两种自由生存的线虫物种-Leptolaimoides brevicaudatus sp。的图解说明。。和Paramonhystera affinis sp。n。—介绍了越南的水域。L.短尾类似于L. thermastris（洛伦，1966）; L.gangioensis Hoang Lai-Phu等，2009; 和L. asiaticus Gagarin，Nguyen Vu Thanh，2005年在体型上有所不同，但与这些物种的不同之处在于：其体型较短且较苗条，针尖较长，并且男性没有泄殖腔前补充剂。副猪嗜血菌 。在形态上类似于P. parabutschlii（Timm，1961）和P. levicula （Lorenzen，1972），但是它具有较短且稀疏的体毛刚毛，六个外唇刚毛（两个比较物种中四个外唇刚毛），以及短针。
