Abstract
Two new diving beetle species of the subtribe Deronectina are described from south-eastern Anatolia. Deronectes kabilcevz sp. n. belongs to the D. longipes-subgroup of the D. parvicollis-group. It is externally similar to the other members of this subgroup, but can be separated by the different shape of the median lobe of aedeagus. Deronectes propedoriae sp. n. belongs to the D. doriae-group. Analysis of molecular studies suggests that the new species and D. doriae Sharp, 1882 are closely related but undoubtedly different with an uncorrected p distance of 7% in the cytochrome oxydase gene. Also external characters allow an easy separation although only the female holotype of the new species is known—the pronotum and the last abdominal ventrite of each have very different shapes. The habitus, the genitalia and other features of the species are illustrated. The keys to species of the respective groups of genus Deronectes are updated. Including the results of this study, 61 species of Deronectes are now known.
