摘要：
Oloncholaimus piipi gen. et sp. nov. is described from Piip submarine volcano, the Bering Sea. Oloncholaimus gen. nov. shows all main characters of Oncholaiminae: females monodelphic-prodelphic with antidromously reflexed ovary, three teeth with left ventrosublateral the largest, oncholaimoid type of Demanian system. New genus can be differentiated from all other genera of the family Oncholaimidae by the complex shape of dorsal and right ventrosublateral teeth with apical antler-shaped extension. Oloncholaimus piipi sp. nov. has large body (5960-7045 mu m), six outer labial and four cephalic setae equal in size (5-7 mu m), equal spicules (110-131 mu m long) without gubernaculum, and complex precloacal supplementary organ composed of 8-9 cylindrical processes.
