ABSTRACT
A new free-living marine nematode belonging to the genus Leptolaimus was discovered in the Bohai Sea, China, and is described here as Leptolaimus boucheri sp. nov. The new species is characterised by males having a papillary, four tubular and 15–21 alveolar precloacal supplements, females having only one tubular pre-anal supplement; cephalic sensilla very short and papilliform. The species can be distinguished from others of the genus by both males and females having precloacal or pre-anal supplements, and males with both tubular and alveolar precloacal supplements, females with only one tubular pre-anal supplement. An identification key for the group of Leptolaimus species characterised by the presence of both alveolar and tubular precloacal supplements is also given.
