AB  - 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.
