A new species Otiorhynchus (Hanibotus) nabozhenkorum Davidian et Savitsky, sp. n. is described from Southeastern Turkey. It is closely related to O. sulcibasis Reitter, 1895 and
O. angustifrons Stierlin, 1883, from which differs in the following characters: ventral wall of vagina between of the coxites with markedly sclerotized plate, elytra with distinct hair-like vestiture, disk of elytra slightly convex in lateral view, its sutural interstriae impressed in the middle part. A key to species from species group sulcibasis is given.
