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).
