description AbstractThe holotype female of Andrassya tundrovi Gagarin, 1993 is re-examined. Malakhovia chernobyli gen. n., sp. n. from the water reservoir (cooler) of Chernobyl Atomic Energy Station (northern Ukraine) is described based on several female specimens. The two genera Andrassya and Malakhovia are placed in a new family, Andrassyidae fam. n., characterised by presence of six setae in the cephalic sensilla pattern, pocket-like amphids, slender pharynx with posterior widening, paired outstretched ovaries, acute tail without evidence of caudal glands or spinneret. Malakhovia gen. n. differs from Andrassyia mainly in having a small buccal capsule and oviparity. Morphological traits and relationships of the two genera are discussed. The family Andrassyidae is tentatively placed in the order Enoplida. Description d'Andrassya tundrovi Gagarin, 1993 et de Malakhovia chernobyli gen. n., sp. n. (Nematoda: Andrassyidae fam. n.) - L'holotype femelle d'Andrassya tundrovi Gagarin, 1993 a ete examine. Malakhovia artemisiae gen. n., sp. n. provenant du reservoir d'eau de refroidissement de la centrale atomique de Chernobyl (Ukraine du nord) est decrit sur plusieurs specimens femelles. Les deux genres sont reunis dans la nouvelle famille des Andrassyidae fam. n. caracterisee par le developpement de six soies parmi les sensilles cephaliques, des amphides en forme de poches, un pharynx mince mais elargi posterieurement, deux ovaires replies, une queue pointue depourvue de glandes caudales et de filiere. Le genre Malakhovia gen. n. differe essentiellement du genre Andrassya par la presence d'une petite capsule buccale et son oviparite. Les caracteristiques morphologiques et les relations entre les deux genres sont discutees. La famille des Andrassyidae est placee avec quelques hesitations dans l'ordre des Enoplida.
