| Glochinema bathyperuvensis sp. n., the first record of Epsilonematidae from bathyal muddy sediments of the oxygen minimum zone (OMZ) off Callao, Peru (eastern Pacific Ocean) is described. The new species belongs to the subfamily Glochinematinae and is characterized by the possession of more than 8 pairs of subdorsal thorns asymmetrically arranged and a single dorsal one in the pharyngeal region, as well as by the presence of ten to thirteen blade-like cuticular protrusions forming a latero-dorsal palisade around the posterior head region and anterior cervical region. In addition, G. bathyperuvensis is characterized by its large size, more than 240 cuticular annules, provided with an extremely dense „hairy“ body ornamentation and, four rows of ambulatory... |

| Morphological features of the cuticular appendages, such as spines, thorns, setae and flaps are described on the basis of SEM pictures of three new and three known species of the Epsilonematidae from East African coasts. Epsilonema espeeli sp.n. is characterized by the presence of six subcephalic setae and a large number of hair-like spines on the dorsal body side; males are characterized by three pairs of copulatory thorns, three precloacal thorns and an anal tube; females have a large citucular flap covering the vulva. Metepsilonema iuvenisspinosum sp.n. is characterized by its small size, ornamentation and shape of the body annules, conspicuous inversions in direction of the body annules (3 dorsal inversions and 1 ventral inversion), oval amphid, 4... |
