Figs 1A , 2A–D

Type material. Holotype ♂ ( ZMUT), IRAQ: Erbil Governorate: Soran, Bradost Mt., Beston Cave , 36°42'29.8"N 44°23'32.5"E, 08.05.2023 (F.A. Khudhur) . Paratypes: 2♂ ( ZMUT), same as for the holotype .

Etymology. The specific epithet is a noun in apposition, referring to a dialect of the Kurdish language that is spoken in the most parts of Iraqi Kurdistan, as well as the Kurdistan Province, Kermanshah Province, and West Azerbaijan Province of western Iran.

Diagnosis. The new species is most similar to T. domestica (Clerck, 1757) and T. alamto Zamani, Marusik & Malek-Hosseini, 2018 in having two retrolateral apophyses, a relatively short conductor with only the retrolateral arm developed, and a short embolus. It can be distinguished by the total absence of the prolateral arm of the conductor (vs. a small extension present), a thin embolus originating at ca. 10 o’clock position (vs. the embolus in T. domestica thick, and in both species originating at 9 o’clock position), and the aspinose palpal tibia (vs. spinose) (cf. Fig. 2A and Cazanove et al. 2022: fig. 2A, D and Zamani et al. 2018: fig. 1).

Description. Male (Holotype). Habitus as in Fig. 1A . Total length 6.55. Carapace 3.75 long, 2.70 wide. Eye sizes: AME: 0.15, ALE: 0.20, PME: 0.18, PLE: 0.19. Carapace and sternum yellowish brown, carapace darker in pars cephalica, without any pattern. Labium, chelicerae, and maxillae brownish. Legs of same color as carapace and with faint annulations. Abdomen light beige, with scattered dark gray patches on dorsum and without any pattern ventrally. Spinnerets dark beige. Measurements of legs: I: 25.55 (6.90, 1.60, 7.07, 7.18, 2.80), Fe II: 6.74 (the rest of the segments missing), III: 20.62 (5.80, 1.35, 5.12, 6.40, 1.95), IV: 23.02+missing Ta (6.95, 1.50, 6.27, 8.30, missing).

Palp as in Fig. 2A–D ; tibia 2 times longer than wide with 2 retrolateral apophyses, one rectangular heavily sclerotized (Ts) and another weakly sclerotized (Tw) as long as tibia wide; cymbium 1.9 times longer than wide, with tip equal to length of bulb; bulb almost as wide as long; tegular apophysis (Ta) located posteriorly, originating at ca. 6 o’clock position, bent at right angle, terminal part as long as basal; conductor (Co) wider than long, prolateral arm lacking, retrolateral arm (Cr) wide and not pointed; embolus short and thin, originated at ca. 10 o’clock position, forming ca. 180º loop.

Female. Unknown.

Distribution. Known only from the type locality in Erbil Governorate, Iraqi Kurdistan ( Fig. 10 ).
