Seven specimens of the family Benthimermithidae from the Clarion-Clipperton Fracture Zone ( Eastern Tropic Pacific), from the depths 4,800-5,040 m, were examined. Bathynema nodinauti gen. et sp. n. is described. The new genus differs from other genera of Benthimermithidae by the presence of an inner pharyngeal lumen. Four new species of Trophomera are also described. Body length of female of T. elegantis sp. n. approximately 1.5 mm; body cylindrical, anterior and posterior ends in shape of rounded cone; cephalic setae 2.0-2.5 mu m long; trophosome consisting of 1 row of cells; female reproductive system didelphic, amphidelphic, occupying approximately 1/6 of total body length; ovaries reflected; diameter of mature eggs 17 mu m; males not found. Body length of female of T. minutissima sp. n. 0.9 mm; body cylindrical, with thickest body part at anterior half of body; anterior and posterior ends rounded; cephalic setae 1.5 mu m long; trophosome consisting of 1 row of cells; female reproductive system didelphic, amphidelphic, occupying approximately 1/3 of total body length; ovaries reflected; size of mature eggs 24x23 mu m; males not found. Body length of female of T. pacifica sp. n. 5.4 mm; body cylindrical, anterior end rounded; posterior end conical, with thick conical terminal spine 81 mu m long, showing granular core; cephalic setae 2.5 mu m long inserted in tiny pits; trophosome consisting of 1 row of cells; female reproductive system didelphic, amphidelphic, occupying approximately 2/3 of total body length; ovaries outstretched; size of mature eggs 34x20 mu m; males not found. Body length of female of T. senckenbergi sp. n. 1.6 mm; body fusiform; anterior and posterior ends in shape of a cone with rounded tip; cephalic setae 2 mu m long; trophosome consisting of 1 row of cells; female reproductive system didelphic, amphidelphic, occupying approximately 1/6 of total body length; ovaries non-reflected; males not found. The new finding of T. marionensis is recorded. One rest specimen (in bad condition) of a new species is described as a morphotype. A dichotomous key to the genera of the Benthimermithidae and tabular keys to Trophomera species are presented.
