Taxonomic notes on African species of the genus Brevitobrilus (Nematoda, Enoplida: Tobrilidae)
S.J. Tsalolikhin
Abstract. The genus Brevitobrilus Tsalolikhin, 1981 can be divided into two groups according to the distance from the cloaca to the first supplement. Using this character and material from some African lakes (mostly collected by the author in Ethiopia), species of the genus have been partly revised. New species: B. kenyensis (= Trilobus graciloides sensu Allgen, 1952 and Tobrilus and Tobrilus graciloides sensu Andrassy, 1964). New synonymy: B. graciloides (Daday, 1908) = B. africanus (Zullini, 1988). Specimens described by Joubert & Heyns (1979) as B. stefanskii (Micoletztky, 1925) were misidentified, they belong to B. granatensis (Ocaña & Zullini, 1988). The neotype of B. graciloides is designated.
