A nematode species Raillietnema synodontisi Vassiliades, 1973 (host S. ocellifer), is redescribed using morphometric (including scanning electron microscopy) and molecular characteristics and transferred into the genus Labeonema Puylaert, 1970. It is morphologically and metrically similar to Labeonema intermedium Puylaert, 1970, the other congeneric species (L. bainae Baker, 1982; L. bakeri Van Waerebeke, Chabaud, Bain et Georges, 1988; and L. africanum Moravec et Van As, 2004) differ from them either by the spicule and gubernaculum lengths, distribution and number of pre-cloacal papillae, position of the vulva, as well as hosts and geographical distribution. The partial sequences of small ribosomal subunit rDNA of L. synodontisi were analyzed and compared with other nematode sequences. Molecular analyses seem to support the position of this nematode species based on the morphological observation.

Druh hlístic Raillietnema synodontisi Vassiliades, 1973 (hostitel Synodontis ocellifer), je redeskribován morfometrickými (včetně rastrovací elektronové mikroskopie) a molekulárními charakteristikami a přeřazen do rodu Labeonema Puylaert, 1970. Parciální sekvence malé ribosomální podjednotky z DNA druhu L. synodontisi byla analyzována a porovnána se sekvencemi jiných hlístic.
