Description of two free-living nematode species of Halomonhystera disjuncta complex (Nematoda: Monhysterida) from two peculiar habitats in the sea
Morphological descriptions of two Halomonhystera species (Nematoda, Monhysterida) are presented ( Halomonhystera hermesi and Halomonhystera socialis ). Halomonhystera hermesi sp. n. occurs in a dense monospecific and homogeneous population on bacterial mats in the Håkon Mosby mud volcano in the Bare...
