First Record of Free-Living Marine Meiobenthic Nematode Oncholaimellus calvadosicus De Man 1890 (Enoplida: Oncholaimidae) from Northern-East Coast of India

The taxonomic work on free-living marine Nematodes in Indian subcontinent is very scanty. Apart from the works by Timm (1956, 1961 & 1967) from the seas around the Indian waters, Gerlach (1962) from Maldives Islands and Warwick (1973) from Indian Ocean, not much published work were available on marine free-living nematode systematics. All together Timm (1956, 1961 & 1967), Gerlach (1962) and Warwick (1973) described more than 130 species from Indian Ocean around this country. Except the work of Timm (1961, 1967) the coastal part of West Bengal is almost untouched for marine free-living nematodes taxonomic work.
