Type material.
Holotype • ♂ (ZMUT), Turkiye: Antalya Prov.: Alanya, env. Kestel, Dim Valley, 36°32'34.5"N, 32°06'17.5"E, 110 m, pine and oak forest, 2.01.2013 (Y. M. Marusik). Paratypes: • 4 ♂ (ZMUT), same data as for the holotype.
Diagnosis.
The new species belongs to the ariadnae species-group and is most similar to T. averni. The male of the new species differs from that of T. averni by having thickened male palpal femur with four strong dorsal spines (Fig. 14 B), an almost straight embolus on the prolateral half (vs roundly bent), a relatively shorter tibia with a length / width ratio of 2.5 (vs 2.9), and a conductor with subequal arms (vs a distal arm that is longer than the proximal arm; cf. Figs 14 A, 13 A).
Description.
Male. Habitus as in Fig. 18 D. Total length 4.00. Carapace 1.95 long, 1.55 wide. Eye sizes: AME: 0.04, ALE: 0.07, PME: 0.06, PLE: 0.07. Pars cephalica, chelicerae, labium, maxillae, and Fe I and II pale brown, Fe II paler than I; pars thoracica, sternum, and remaining leg segments pale brown. Legs without annulations. Fe I, and to lesser degree Fe II, with ventral coating of long setae. Abdomen pale beige, without patterns. Spinnerets uniformly pale beige. Measurements of legs: I: 9.00 (2.36, 0.78, 2.24, 2.24, 1.38), II: 7.95 (2.16, 0.74, 1.85, 1.93, 1.27), III: 7.39 (1.93, 0.67, 1.65, 2.00, 1.14), IV: 9.78 (2.55, 0.75, 2.36, 2.74, 1.38).
Palp as in Fig. 14 A – D; femur 4 × longer than wide, longer than cymbium, 1.5 × wider than tibia, with 4 strong spines in distal 1 / 2 (Fig. 14 B); patella 2 × longer than wide; tibia 2.25 × longer than wide, with retroventral (Rv) and retrodorsal (Rd) apophyses (Fig. 14 B); cymbium> 2 × longer than wide, tip approximately as long as cymbium wide, with two strong macrosetae (= spines) on retrolateral 1 / 2; bulb as long as wide; median apophysis (Ma) long, approximately as long as width of tibia, originating at ~ 5 o’clock position (Fig. 14 A); conductor fungiform, with both arms of equal length and width; embolus originating at ~ 8 o’clock position, straight in prolateral 1 / 2 of bulb and strongly roundly bent proximally at retrolateral side.
Female. Unknown.
Comments.
Although the specimens of both T. hamid and T. beyazcika sp. nov. (known only from females and males, respectively) were collected from the same locality, we consider them to belong to different species due to noticeable differences in size and coloration. Additionally, T. hamid has a different conformation of the copulatory organs compared to those of the species in the ariadnae group, thus belonging to a different species-group than T. beyazcika sp. nov. Given the pale coloration of this species, the relatively elongated legs, and the dense ventral coating of long setae on femora I and II, it seems that the collection locality mentioned on the label is slightly off. It is more likely that the species was collected from a cave, such as the nearby Dim Cave.
Distribution.
Known only from the type locality in Antalya Province, southwestern Turkiye.
Etymology.
The specific epithet is derived from the Turkish word " beyaz ", meaning pale, combined with the suffix - cik, meaning little. This refers to the relatively small size and pale coloration of this species.
