Discussion To date, three species are known belonging to the subgenus Brentalebertia , namely Lebertia minutipalpis K.Viets, 1920 from Central Europe, L . hygropetrica Gerecke, 2008 from the Southern Alps and L . hupalupu Gerecke, 2009 from the Canary Islands. Lebertia anatolica differs from all other species of the subgenus in having two ventrodistal setae on P-3. This plesiomorphic character state was previously known only from the subgenus Eolebertia and the genus Paralebertia . Members of both taxa are characterized by, and differ from the Lebertia species of the remaining subgenera in, higher number of setae on P-2, -3 and -4. Furthermore, the characteristic (ventrally bent tips of Cx-I) demonstrate that L. anatolica has to be placed in Brentalebertia . Lebertia anatolica is similar to L . hupalupu in the combination of the acetabula without central constrictions and Cx-I / II nearly equal in length (Cx-I / II mL ratio in L . hupalupu : 0.94). That species differs in an unsclerotized excretory pore, P-3 with only five setae and IV-L-6 with three stout ventral setae. Figure 2.
