Spermophorodrilus antiquus (Černosvitov, 1938)

Bimastos antiquus bouchei Zicsi & Michalis 1981 Acta Zool. Hung. 27: 245. (Omodeo & Rota 1989)

Remarks. Bimastos antiquus bouchei differed from the nominal subspecies by its shorter clitellum (1/2 23 –29 vs. 23–30). Omodeo & Rota (1989) recognized that the clitellum slightly varies in this species and that the different subspecies proposed ( Allolobophora antiqa michalisi Karaman, 1972 and Bimastus antiquus bouchei) are devoid of taxonomic significance.
