Abstract

Six new nematode species are described from the sediment of a manganese nodule area of the abyssal eastern South Pacific: Aponema nympha sp.n., Caligocanna mirabilis gen.n. sp.n., Microlaimus discolensis sp.n., M. clancularius sp.n., M. porosus sp.n., and Bathynox clavata gen.n. sp.n.. The new genera Caligocanna and Bathynox are considered to belong to the Microlaimidae MICOLETZKY, 1922. The genus Caligocanna gen.n. differs from all other genera of the family Microlaimidae in combining the following characters: The six cephalic setae of the second circlet longer than the four cephalic setae of the third circlet. Annulated cuticle; annules with numerous longitudinal bars. Monospiral amphids turn ventrally. The genus Bathynox gen.n. differs from all other genera of the family Microlaimidae in having projecting, club-shaped corpora gelata and somatic setae positioned on peduncles.
