Figs 8–20 , 57

Types. ♂ Holotype (ZMFUM-LYC-0013) and 3♂ paratypes (ZMFUM-LYC-0014 to 0016), IRAN, Golestan Province: Golestan National Park, Mirzabailou , 37.46°N, 56.13°E, 1256 m a.s.l., 10. Jun. 2014, H. Maddahi leg.

Etymology. The species epithet is latinized adjective derived from the name of the type locality, the Golestan National Park in Golestan Province, Iran.

Diagnosis. The male of K. golestanica sp. n. is most similar to that of K. shmatkoi ( Logunov & Ponomarev 2020: figs 115, 118, 123–125) in having a hook-shaped proximal extension of the median apophysis and a serrate flange in the median tooth of the median apophysis. It is also similar to K. turanica Logunov & Ponomarev, 2020 ( Logunov & Ponomarev 2020: figs 161, 164) by the shape of the median tooth. K. golestanica sp. n. can be distinguished from the former species by 1) quadrangular median tooth ( Figs 14–16 , 18–20 ); 2) the shape of the synembolus: apical lamellae basalward-sloping straight, and basal lamellae acutely bent apicalward ( Figs 15–16 , 17–19 ); 3) acutely pointed conductor bending at its tip ( Figs 15 , 18 ). It can be separated from the latter species by 1) hook-shaped proximal extension of the median apophysis ( Figs 14–16 , 18–19 ); 2) the presence of a low serrate flange at the base of the median tooth of the median apophysis ( Fig. 20 ); 3) the conductor tip bent ( Figs 15 , 18 ); and 4) the basal lamellae of the synembolus acutely bent apicalward ( Figs 15 , 19 ).

Description. Male (holotype). Total length 22.35. Carapace 11.4 long, 8.85 wide.

Prosoma. Carapace entirely brown, densely covered with white setae ( Fig. 8 ) and without marginal stripes ( Fig. 8 ). Sternum yellow, covered with short white setae and scattered long black setae ( Fig. 9 ). Chelicerae brown, covered with white setae proximally and brown setae distally, black longitudinal stripes on chelicerae retrolaterally ( Fig. 10 ). Clypeus yellow, covered with white and black setae ( Fig. 10 ). Endites and labium light brown, covered with black setae ( Fig. 8 ).

Eyes. Sizes and interdistances: ALE 0.4; AME 0.6; PLE 1.05; PME 1.2; ALE–AME 0.3; AME–AME 0.4; PME–PME 1.2.

Opisthosoma. Dorsum yellow, with black marks and spots; cardiac mark brownish, with black edging. Venter yellow, covered with white setae. Spinnerets yellow, posterior and anterior spinnerets covered with white and black setae, respectively ( Figs 8–9 ).

Legs. Dorsal aspect: coxae and trochanters I–IV light brown; femora, patellae and tibiae I–IV light brown; metatarsi and tarsi: I–II dark brown, III–IV light brown; coxae, trochanters, femora and patellae of all legs covered with long and dense white setae in addition to sparse short black setae; tibiae of all legs and metatarsi and tarsi III–IV covered with a sparse fringe of long black protruded setae; metatarsi and tarsi I–II covered with dense short brown setae ventro-laterally and short white setae dorsally. Ventral aspect: coxae, trochanters and femora I–IV light brown, densely covered with short white setae and with sparse long, black setae; patellae light brown, with a pair of grey parallel marks on proximal margins, which are darker on legs I–II; tibiae I–II light brown proximally and dark brown distally; tibiae III–IV light brown. Tibiae of all legs and metatarsi and tarsi III–IV covered with dense short yellowish setae and long black protruded setae; metatarsi and tarsi I–II black, covered with dense short light brown setae and sparse black protruded setae; metatarsi III–IV light brown ( Figs 11–13 ); tarsi of all legs with scopulae and spinules. Measurements and spination as in Tables 3–4 .

Palp. Palp as in Figs 14–20 . Femora and patellae light brown and densely covered with short white setae. Tibiae light brown with a black ring distally, venter and lateral sides (especially prolateral) are covered by a dense fringe of very long, erect grey setae with white tips. Cymbium darker than other segments of palp, covered with short white setae and curly, long light brown setae only on the prolateral part. The outer plate of the median apophysis with Spermathecal head 3 times wider 3 processes arranged clockwise; lateral process rather wider than long, and beakshaped; proximal extension of the median apophysis is wider than other two processes and markedly hook-shaped and its tip slightly sharpened; median tooth of the median apophysis developed as a large median claw, with small prolateral teeth, and also with flange situated ventro-proximally; and the inner plate of the median apophysis large, transverse-ovoid, retrolateral shoulder bent ventrad ( Figs 15–16 , 18–19 ). Conductor triangular, acutely pointed with a bent tip. Synembolus needle-like, with 2 lamellae convergent to each other: the apical lamella basalward-sloping straight, the basal lamella acutely bent anteriorly.

Female: Unknown.

Distribution. Known only from the type locality ( Fig. 57 ).
