Figs 1–6 , 13–16 , 21–25 , 28

M. cariae: Logunov, 2012: 376 [examined, misidentification]

Type material. ♂ holotype , 2♀ paratypes; Turkey, Muðla, 7 km east of Dalaman , pine forest, 06.03.1977, leg. R . Kinzelbach ( SMF) ; 1♂ 1♀ paratypes, with the same data as for the holotype ( NMNHS) . 1♂ paratype; Turkey, Antalya Province, near Kalkan village , 04.2003, L. Cook leg. ( MMUE, collection number G7535.36)

Etymology. Named after the Anatolian Peninsula, where the type material was collected.

Diagnosis. The species is morphologically close to Maimuna cariae Brignoli, 1978 by the shape of the conductor of the male palp, and especially by the twisted lamellar terminal end of its ventral part, as well as by the shape of the epigynal hood and the notched epigynal field. The two species can be separated by (1) the shape of the median apophysis of the male palp that is narrow and pointed apically in Maimuna anatolica sp. n. ( Figs 4 , 21 ) vs. more massive and with irregular shape in M. cariae ( Figs 7 , 26 ); and (2) the wider receptacles ( Figs 16 , 25 ) than in M. cariae ( Fig 18 ).

Description. Male ( Figs 1–2 , 4–6 , 21–23 ). Measurements. Total length 7.10; carapace length 3.74, width 2.42; sternum length 1.74, width 1.56; labium length 0.44, width 0.46; maxilla length 0.75, width 0.54; chelicera length 1.39, width 0.67; clypeus height (under AME) 0.34; palp cymbium length 1.47; eye diameters: AME 0.09, ALE 0.09, PME 0.20, PLE 0.09; interdistances between the eyes AME–AME 0.09, AME–ALE 0.04, AME–PME 0.05, ALE–PLE 0.08, PME–PME 0.11; abdomen length 3.36, width 2.00; PLS basal segment length 0.62, distal segment length 1.23; leg I—10.38 (1.48, 2.22, 0.93, 1.91, 2.36, 1.48), leg II—10.64 (1.47, 2.39, 1.05, 1.83, 2.37, 1.53), leg III—10.51 (1.43, 2.28, 0.97, 1.83, 2.63, 1.37), leg IV—12.89 (1.66, 2.78, 1.16, 2.37, 3.46, 1.48). Spination. Chaetotaxy typical for the genus.

Coloration ( Fig 1 ). Carapace yellow to light brown, with an indistinct lighter area at the middle of the dorsal side and slightly darker cephalic area and chelicerae. Fovea represented by a short dark stripe. Legs yellowish, without pattern, slightly lighter than the carapace. Sternum yellow, with slightly visible darker pattern. Palpal segments colored as legs. Abdomen dorsally light brown-gray with narrow yellowish longitudinal strip and 7–8 short yellowish radial strips. The ventral side uniformly light gray. Spinnerets yellowish.

Other somatic characters. The cephalic area distinctly narrower and more elevated than thoracic area. The PER recurved (as seen from dorsal view). Chelicerae massive, bulged frontally, with opistognathic position. Three short promarginal and 2 very small retromarginal cheliceral teeth present. The retromarginal teeth positioned against the prolateral ones. Fovea smooth, black, well visible. Trochanters straight or slightly convex.

Palp ( Figs 2 , 4–6 , 21–23 ). Without patellar or tibial apophyses. Femur with distinct perpendicular ridge on the retrolateral side ( Fig 2 ). Tibia with elongated ventral ridge. Tegulum brown, with well sclerotized basal part. Embolus thin, starting at 13 o’clock. Conductor large and complex, with wide latero-dorsal projection. Lateral margin wide, forming a deep groove that extends into the lateral projection. The terminal end of the ventral part of the conductor modified in twisted lamellar extension. Median apophysis long with wider triangular base, narrowing apically, with a thin pointed tip.

Female ( Figs. 3 , 13–16 , 24–25 ). Measurements. Total length 8.50; carapace length 3.78, width 2.36; sternum length 1.81, width 1.54; chelicera length 1.60, width 0.84; clypeus height (under AME) 0.24; eye diameters: AME 0.15, ALE 0.18, PME 0.26, PLE 0.17; interdistances between the eyes as in male; abdomen length 4.72, width 3.18; epigyne width 0.37; PLS basal segment length 0.63, distal segment length 1.55; leg I—9.96 (1.50, 2.39, 1.03, 1.71, 2.04, 1.29), leg II—9.99 (1.63, 2.22, 0.97, 1.71, 2.06, 1.40), leg III—9.73 (1.33, 2.29, 1.03, 1.64, 2.19, 1.25), leg IV—12.49 (1.67, 2.65, 1.15, 2.34, 3.18, 1.50). Coloration and other somatic characters as in male, abdomen slightly paler ( Fig 3 ).

Epigyne ( Figs 13–15 , 24 ) with wide epigynal hood. The epigynal field deeply notched. The notch long and narrow, reaching half of the epigynal field. Copulatory openings situated under the epigynal hood. Vulva ( Figs 16 , 25 ). Receptacles large, with irregular shape. Fertilization ducts ribbon-shaped.

Distribution ( Fig 28 ). Known only from the two type localities in the easternmost Anatolia, Turkey.
