The taxonomic problems associated with the validity of subgeneric names in the genus Omocestus I. Bobvar, 1878 are discussed. The subgeneric names Haplomocestus Tarbinsky, 1940 and Dreuxius Defaut, 1988 proposed after 1930 are unavailable according to Articles 13.1 and 13.3 of the Code (ICZN, 1999). Here the genus is divided into three subgenera, namely Omocestus s. str. [type species - Omocestus viridulus (Linnaeus, 1758), by subsequent designation (Kirby, 1910)], Dirshius Harz, 1975, stat. resurr. [type species - Omocestus haemorrhoidalis (Charpentier, 1825), by original designation] and Tarbinskius subgen. nov. [type species - Omocestus bolivari Chopard, 1939, here designated]. The brief diagnosis and species composition are given for each subgenus.
