A novel species of nematode belonging to the rare genus Psammonema Verschelde & Vincx, 1995 is described from the continental margin of the north-eastern Arabian Sea (214 m). Psammonema kuriani sp. nov. shows a different position of the lateral alae compared with the original genus diagnosis, hence an emended genus diagnosis is given. The genus Psammonema was previously described from the estuarine sediments of Indian Ocean region and the present study reports the genus from the deep sea for the first time.
