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.
