Description.

Male (Holotype). Habitus as in Fig. 1B . Total length 6.55. Carapace 3.57 long, 1.22 wide at pars cephalica, 2.37 wide at pars thoracica. Eye sizes: AME: 0.11, ALE: 0.15, PME: 0.22, PLE: 0.16. Carapace, sternum, labium, and maxillae light brown; carapace with darker submedian bands. Chelicerae light reddish brown, each with 3 pro- and 2 retromarginal teeth. Legs yellowish brown, with annulations. Abdomen dorsally dark greyish with lighter foliate pattern, light greyish ventrally. Spinnerets light greyish, darker basally (Fig. 1C ). Measurements of legs: I: 7.48 (2.00, 0.90, 1.53, 1.95, 1.10), II: 7.75 (2.15, 0.89, 1.53, 2.00, 1.18), III: 7.78 (2.00, 0.93, 1.60, 2.20, 1.05), IV: 9.64 (2.55, 0.84, 1.95, 2.97, 1.33). Spination is given in Table 1 .

Palp as in Figs 2A-E , 3A-E , 4A-D , 5A-C , 6A-C ; femur relatively short (ca 3 × longer than wide, 1.5 × shorter than cymbium) and strongly modified: slightly bent, with proximal (Pb) and distal (Db) bulges and 2 outgrowths: spine-like (Sp) and larger stump-like (So). Patella short, wider than long, with ventral apophysis (Va). Tibia slightly wider than long in retrolateral view, with retrolateral (Rt) conical apophysis directed laterally, ventral keel (Kt) and prolateral apophysis (Pt). Cymbium droplet-shaped, ca 1.7 × longer than wide, with small baso-prolateral fold (Cf). Subtegulum (St) round, hidden by tegulum and conductor. Tegulum (Te) small, round, hidden by conductor and embolus base. Conductor very large, ca 0.7 × shorter than cymbium; anterior and posterior parts extending over tegulum; anterior arm (Ca) as long as wide, posterior arm (Cp) more than 2 × longer than wide; posterior part of posterior arm very broad and extending ventrally; tip of posterior arm trifurcate. Embolus proper originates at about 8 o’clock position and terminates at about 5 o’clock position; base of embolus (Eb) not rounded: mesal part straight, prolateral part bent on right angle.

Female (Paratype, ZMUT). Habitus as in Fig. 1A . Total length 6.75. Carapace 2.95 long, 1.16 wide at pars cephalica, 2.97 wide at pars thoracica. Eye sizes: AME: 0.10, ALE: 0.15, PME: 0.22, PLE: 0.14. Coloration generally as in male, except for darker submedian bands on carapace and more distinct annulations on legs. Measurements of legs: I: 6.55 (1.80, 0.87, 1.30, 1.58, 1.00), II: 6.73 (1.87, 0.93, 1.30, 1.57, 1.06), III: 6.98 (1.90, 0.90, 1.33, 1.85, 1.00), IV: 9.05 (2.29, 1.04, 1.92, 2.60, 1.20). Spination is given in Table 1 .

Epigyne as in Fig. 7A-G ; epigynal plate 1.6 × wider than long; fovea lacking depression, weakly sclerotized with thin septum (Se), anterior part delimited by well sclerotized margin, posterior part delimited by weakly sclerotized margins; septum not covered by setae; copulatory openings (Oc) located on posterior margin on both sides of septum; copulatory ducts (Cd) fused, forming a rectangular plate ca 2 × longer than wide (Fig. 7G ); receptacles (Re) small, suboval, located anteriorly and separated by ca one length of each; fertilization ducts (Fd) short and small.

Natural history.

The specimens were collected off their funnel-webs constructed under the stones or within shrubs and crevices in the soil. The habitat is a typical maquis shrubland dominated by Quercus L. ( Fagaceae ) and Pinus L. ( Pinaceae ) at Erdemli (Mersin), while it is dominated by Abies Mill. ( Pinaceae ) at Pozantı (Adana).

Distribution.

Known only from the provinces of Mersin and Adana, southern Türkiye.
