Karakumosa yahaghii sp. n.

Figs 33–44 , 57

Type. ♂ Holotype (ZMFUM-LYC-0018), IRAN, South Khorasan Province: Sarayan County, 33.53°N, 58.34°E, 1484 m a.s.l., Jul. 2018, M. Amini leg.

Etymology. The species name is a patronym honoring the contemporary Iranian writer, literary critic, editor, translator and distinguished professor of literature at Ferdowsi University of Mashhad, Mohammad-Jafar Yahaghi (b. 1947 in Ferdows, South Khorasan, Iran). He is known for his works on Iranian epic literature.

Diagnosis. This species is most similar to K. tashkumyr Logunov & Ponomarev, 2020 by the shape of the inner plate of the median apophysis and presence of a low serrate flange at the foot of the median tooth. The male of K. yahaghii sp. n. can be distinguished by 1) the apical lamella of the synembolus being bent posteriorly and the basal lamella being gradually bent anteriorly ( Figs 39 , 41–42 , both tips of the lamellae markedly bent basalwards in K. tashkumyr ); 2) the conductor acutely pointed and bent at its tip ( Figs 40 , 43 , obtuse in K. tashkumyr ).

Description. Male (holotype). Total length 20.85. Carapace 12 long, 9.45 wide.

Prosoma. Carapace reddish-brown, densely covered with white setae, with anterior heart-shaped yellow median band just behind PLEs and fovea ( Fig. 33 ); marginal stripes absent ( Fig. 33 ). Sternum yellow, covered with short white and sparse long black setae ( Fig. 34 ). Chelicerae almost yellow, with reddish-brown distal ends, covered with dense white and sparse black setae ( Fig. 35 ). Clypeus yellow, covered with dense white and sparse black setae ( Fig. 35 ). Endites brown anteriorly and yellow posteriorly, labium brown, covered with black setae ( Fig. 34 ).

Eyes. Sizes and interdistances: ALE 0.3; AME 0.6; PLE 1.05; PME 1.35; ALE–AME 0.3; AME–AME 0.3; PME–PME 1.2.

Opisthosoma. Dorsum whitish-yellow with black marks and spots; cardiac mark whitish-yellow and bordered in black. Venter yellow, covered with white setae. Spinnerets yellow, covered with white setae anteriorly and black setae posteriorly ( Figs 33–34 ).

Legs. Dorsal aspect: all coxae and trochanters black; femora reddish-brown; patellae greyish anteriorly and yellow posteriorly; all tibiae yellow, with reddish stripes on posterior sides of tibiae III–IV; metatarsi and tarsi: I–II dark brown, III–IV light brown. Coxae, trochanters, femora and patellae of all legs covered densely with long white setae and sparsely with short black setae; all tibiae and metatarsi and tarsi III–IV densely covered with white setae, plus with a disperse fringe of long black protruded setae; metatarsi and tarsi I–II densely covered with 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 sparsely with long black setae; patellae light brown, with a pair of grey parallel marks on proximal margins which are darker on leg IV; tibiae I–II yellow proximally and black distally; tibiae III–IV yellow; all tibiae and metatarsi and tarsi III–IV densely covered with 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, two longitudinal black stripes dorsally on metatarsi I; metatarsi III–IV reddish-brown ( Fig. 37 ); all tarsi with scopulae and spinules. Measurements and spination as in Tables 7–8 .

Palp. Palp as in Figs 38–44 . Femora and patellae yellow and densely covered with short white setae. Tibiae yellow, with black rings distally, ventral and lateral sides (especially prolateral) with dense fringe of very long protruded black setae with white tips. Cymbium light brown, covered with short white setae and curly long light brown prolateral setae. Median apophysis with the lateral process rather wider than long and beak-shaped; the markedly hook-shaped proximal extension, sharpened at tip; median tooth markedly bifurcated, with small prolateral teeth comprising a prominent serrate ventral flange ( Fig. 44 ); the inner plate of median apophysis large and transverseovoid, its retrolateral shoulder bent ventrad ( Figs 38–40 , 42–43 ). Synembolus and embolus needle-like. Conductor triangular, acutely pointed and bent at its tip. Synembolus with two convergent lamellae: apical lamellae bent basalward, basal lamellae gradually bent apicalward. Embolus apicalward-sloping straight ( Fig. 41 ).

Female: Unknown.

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