A new genus and six new species of nematodes (Ungellidae, Drilonematoidea) parasitic in earthworms deposited in the Muséum National d’Histoire Naturelle, Paris, are described. Except for Ungella haitiana sp. n., all nematodes were found in West African oligochaetes. Chabaudigella perforata gen. n., sp. n. is distinguished by having a single row of minute pores on each lateral chord, cephalic hooks in a subdorsal pit with cuticularised rims, excretory pore opposite pharyngeal base, post-uterine sac, pouch-like vagina, short, non-cephalate spicules, and bristle-like male caudal sensilla. Ungella haitiana sp. n. is distinguished by presence of large pocket-like amphids, excretory pore posterior to isthmus, slim pharynx, female body posteriorly expanded, ovary tip in tail, vulva post-median, asymmetrical caudal organs, long spicules; U. millsoniae sp. n. by its small size, indistinct amphids, excretory pore posterior to pharynx base, ovary tip posterior to mid-body, distal ovary portion reflexed, female caudal organs large, with cavity, spicules strongly bent; U. agastrodrilii sp. n. by cephalic hooks in subdorsal pit, male with swollen body, short conical tail and symmetrical caudal organs situated shortly posterior to anus. Ungella barbaulti sp. n. is distinguished by its small size, short and thin cephalic hooks, large amphids, vulva median, post-uterine sac absent, and short spicules; U. lamto sp. n. by its small size; cephalic hooks in subdorsal pit, indistinct amphids; post-uterine sac absent, ovary tip between vulva and anus, median vulva, oblique vagina, caudal organs prominent, spicules short, broadly cephalate, precloacal supplement and bristle-like male caudal sensilla present. Keys to genera of Ungellinae and Ungella are given.
