A new species and new records for the subfamily Aleocharinae from Turkey.

In this study, a new Aleocharinae (Coleoptera: Staphylinidae) species from Turkey, Gyrophaena cagatay sp. n. (Aksaray), is described and illustrated. In addition, new records are presented for seven species: Atheta hygrotopora (Kraatz, 1856), Atheta incognita (Sharp, 1869), Atheta ripicola Hanssen, 1932, Brachyusa concolor Erichson, 1839, Ischnopoda leucopus (Marsham, 1802), Ischnopoda subaenea Eppelsheim, 1890, and Liogluta granigera Kiesenwetter, 1850. Photographs of the habitus of male and female specimens are presented. The 8(th) tergite and aedeagus of the male and the spermatheca of the female are also illustrated for the new species. Differential diagnosis guidelines are given for comparisons with Gyrophaena rousi Dvořak, 1966.
