description: Lebertia (Brentalebertia) anatolica Esen and Dilkaraoğlu, sp. nov.
Type series
Holotype. Male, dissected and slide-mounted in Hoyer’s fluid, Erzincan Province, Kemaliye, Sırakonak stream, 39 ◦ 14 ′ 15 ′′ N 38 ◦ 29 ′ 34 ′′ E, 1015 m asl, 6 September 2011.
Paratypes. One female slide-mounted in glycerine jelly, same data as holotype.
Diagnosis
Integument finely striated; excretory pore sclerotized. Genital field with three pairs of acetabula without signs of transversal constriction (Figures 2A and 2G). Palp stout; P-3 with six setae (two distoventral setae, paired dorsal and dorsodistal setae each close to each other); P-4 ventral margin slightly convex, peg-like mediodistal seta long, robust and pointed, ventral seta insertions dividing segment into sectors 1:1:2.
Description
Both sexes. Colour brownish. Sexual dimorphism in shape of coxal field (Figures 1A, 2A and 2G). Glandularia enlarged. IV-L-1 with three dorsal and three dorsodistal setae, IV-L-5 with seven, IV-L-6 with two ventral setae (Figure 2D), IV-L-5 with one slender distal seta not exceeding 1 / 3 L IV-L-6. Palp (Figures 1B, 2B and 2 E–F), P-2 with concave ventral margin, bearing a robust seta arranged on the bulging ventrodistal edge.
Male (holotype). Idiosoma elongated, L / W 650 / 448, Cx-I / II mL 166 / 170 (mL ratio 0.97), posterior margin Cx-II W 35; coxal field laterally and posteriorly extended Cx-IV extending to level of posterior part of genital flap, posteromedial edge rounded, posterior and posteriolateral margin equally convex; genital flap L 129, with about 16 medial setae, more densely arranged in posterior than in anterior part, and 6 lateral setae, genital field W 100; Ac-1-3 L 40 / 39 / 28; gnathosoma L 190, chelicera L 170, L / H ratio 5.7, basal segment / claw ratio 4.7; palp: L / H, L / H ratio, relative L P-1, 22 / 25, 0.9, 11%; P-2, 49 / 47, 1.0, 24%; P-3, 52 / 31, 1.7, 25%; P-4, 62 / 25, 2.5, 30%; P-5, 20 / 10, 2.0, 10%; total L 205; L / H IV-L-4, 170 / 43; IV-L-5, 189 / 38; IV-L-6 170 / 37.
Female. Idiosoma L / W 912 / 690, Cx-I / II mL 173 / 160 (mL ratio 1.08), posterior margin Cx-II W 47; Cx-IV with acute-angled medioposteriomedial edges, extending to level of halfway Ac-3; genital flap L 178, with about 13 medial setae and 4 lateral setae, genital field W 160; Ac-1-3 L 57 / 55 / 41; gnathosoma L 225, chelicera L 207, L / H ratio 6.5, basal segment / claw ratio 5.1; palp: L / H, L / H ratio, relative L P-1, 23 / 30, 0.8, 10%; P-2, 57 / 50, 1.1, 24%; P-3, 60 / 39, 1.5, 24%; P-4, 78 / 30, 2.6, 32%; P-5, 24 / 13, 1.8, 10%; total L 242; L / H IV-L-4, 191 / 49; IV-L-5, 217 / 50; IV-L-6 189 / 40.
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.
Etymology
