The genus Gunarus Des Gozis, 1886 belongs to the subtribe Cylindrinotina (Coleoptera: Tenebrionidae: Helopini)

The genus Gunarus Des Gozis, 1886 is transferred from the subtribe Helopina to the subtribe Cylindrinotina (Tenebrionidae: Helopini) based on the structure of male aedeagus and presence of posterior ventral grooves of lower aspect of eye in the type species Gunarus hirtulus (Reiche, 1861). New combinations are established: Stenohelops (Stenomaleis) gayirbegi (Nabozhenko et Keskin, 2009), comb. n. (from Gunarus), Stenohelops (Stenomaleis) korkutelensis (Nabozhenko et Keskin, 2009), comb. n. (from Gunarus) and Ectromopsis ovipennis (Allard, 1877), comb. n. (from Gunarus). The species Gunarus arenicola Antoine, 1949 and G. bremondi Antoine, 1949 must be transferred to the subtribe Helopina but its generic position is unknown. Generic position of other 7 Gunarus species must be revised accordingly to the position of the type species G. hirtulus in the system of the tribe Helopini. Key to similar genera Nalassus, Gunarus, Ectromopsis, Xanthomus is given.
