AB  - The description of six species of family Microlaimidae (Nematoda), from
   5,000 m depth at the Clarion-Clipperton Fracture Zone (North-Eastern
   Tropic Pacific), is given. Three previously described species
   (Microlaimus discolensis Bussau et Vopel, 1999; M. porosus Bussau et
   Vopel, 1999; and Caligocanna mirabilis Bussau et Vopel, 1999) were
   found about 5200 km far from the area where the type specimens were
   originally discovered (the Peru Basin, South-East Pacific). Of the new
   species, Aponema martinezi sp. n. is closest to two other Aponema
   species, A. minutissima Kovalyov and Miljutina, 2008 and A. nanum
   (Blome, 1982). However, it differs from them in having a non-set-off
   head, amphids located quite far from the non-annulated cephalic
   capsule, and by possessing the gubernaculum with the apophysis.
   Microlaimus abyssalis sp. n. belongs to a group of Microlaimus species
   with dorsocaudal apophyses of gubernaculum. It differs from other four
   Microlaimus species which have apophyses of similar shape (M.
   crassiceps Gerlach, 1953; M. decraemerae (Muthumbi & Vincx, 1999); M.
   mnazi (Muthumbi & Vincx, 1999); and M. undulates Gerlach, 1953) by
   lacking of supplementary precloacal organs in males and some other body
   parameters. Microlaimus parviporosus sp. n. possesses four submedian
   rows of pores along its entire body length. In this feature it
   resembles three other Microlaimus species (M. cyatholaimoides de Man,
   1922; M. discolensis Bussau and Vopel, 1999; and M. porosus Bussau and
   Vopel, 1999). The new species differs from M. cyatholaimoides and M.
   porosus by the ratio of the length of the outer labial setae and of the
   cephalic setae (approximately of equal length in the new species vs.
   the much longer cephalic setae in two latter species) as well as some
   other parameters. The new species differs from M. discolensis by its
   shorter head setae of two rings (1.2 mu m vs. 6-9 mu m) and some other
   parameters.
