Differential diagnosis. Chitona incana is more similar to C. cretica than C. macedonica sp. nov. because of its aedeagus and the surface of the head and pronotum. It differs from both species by the shortly dilated apices of the projections of urite VIII ( Figs. 30-31 ) and the form of the paramere in both dorsal and lateral view ( Figs. 28-29 , see also the key). The last abdominal segment in both sexes and the aedeagus are very similar to those of C. cretica . This species also has two colour forms as the two preceding species. No distinguishing characters between females of C. cretica and C. incana were found.

Length J ♀: 5.5-9.3 mm.

Distribution. Southwestern Turkey (see also Fig. 32 ).

Comments. According to the present knowledge, the distribution of C. incana is restricted to southwestern Turkey. The data of its occurrence in Greece, published by previous authors, probably belong to either C. cretica or C. macedonica sp. nov.
