摘要
Two new species of free-living marine nematode from mangrove habitats in Xiamen Bay are identified. Anoplostoma tumidum sp. nov. is characterized by relatively short outer labial setae (0.86-1.00 h. d.), long tail (c 7.2-8.9, c' 8.3-10.5), an instinct swollen distal portion of slender spicule (Sc 94-101 mu m), and well developed copulatory bursae without bursal papillae. A. tumidum sp. nov. differs from all valid species of genus Anoplostoma in copulatory apparatus of males with a distinct swollen distal portion of spicule, and a relatively obvious constriction of head. A. paraviviparum sp. nov. is characterized by relatively long outer labial setae (1.11-1.22 h. d.), and tail (c 6.6-8.5, c' 8.6-10.2); elongated spicules with distinct knob-like proximal and pointed distal ends (Sc 46-69 mu m); distinct strip-like gubernaculum (length with 11-15 mu m); well developed copulatory bursae with precloacal papillae and post-cloacal papillae; and a distinct constriction of head. A. paraviviparum sp. nov. is similar to A. viviparum Bastian, 1865, but differs in the reproductive mode of female and the constriction of head.
