Abstract:

One new species and one new record species of Sphaerolaimus are described. Sphaerolaimus longispiculatus sp. nov. is characterized by body length 2 213-2 470 μm, amphideal fovea 12%-16% corresponding body diameters in males and 9%-10% corresponding body diameters in females, long slender spicules 2.8-3.8 cloacal body diameters, eight small papilliform precloacal supplements, gubernaculum without apophysis, and tail conico-cylindrical, 2.5-3.7 cloacal/anal body diameters long. Sphaerolaimus gracilis is recorded from the first time in the mangroves wetlands, it can be distinguished from the original desceiption by longer spicules (66-71 μm vs 56 μm) and wider body (a=20.1-21.4 vs 25).

Key words: free-living marine nematodes|taxonomy|Sphaerolaimus longispiculatus sp. nov.
