Karakumosa shmatkoi Logunov & Ponomarev 2020

Karakumosa shmatkoi Logunov & Ponomarev, 2020 Figs 45–57 Material examined. 1 ♂ (ZMFUM-LYC-0019), IRAN, Razavi Khorasan Province: Kalate Naderi, 36.99°N, 59.72°E, 1050 m a.s.l., Jul. 2017, M. Amiri leg. Diagnosis. The male of K. shmatkoi is very similar to those of K. tashkumyr (Logunov & Ponomarev 2020: figs 145–154) and K. gromovi Logunov & Ponomarev, 2020 (Logunov & Ponomarev 2020: figs 55–60, 64–68); but it can be distinguished from the former by a narrower inner plate of the median apophysis (Figs 50–51, 54, wider in K. tashkumyr) and by an acutely pointed and convergent synembolous lamellae (Fig. 53, both lamellae tips markedly bent basalwards in K. tashkumyr); and from the latter by having a serrated flange at the foot of the median apophysis (Fig. 56, absent in K. gromovi). For a female diagnosis, see Logunov & Ponomarev (2020: 295). Description. Male. Total length 18.3. Carapace 10.8 long, 8.25 wide. Prosoma.

Sternum yellow, covered with short white setae and sparse long black setae (Fig. 46). Anterior half of the chelicerae yellow and covered with white setae, distal half brown and covered with light brown setae, and with black longitudinal stripes retrolaterally (Fig. 48). Clypeus light brown, covered with white and black setae (Fig. 48). Endites yellow, with brown spots retrolaterally, labium brown, both of them covered with black setae (Fig. 46). Eyes. Sizes and interdistances: ALE 0.3; AME 0.45; PLE 1.05; PME 1.05; ALE–AME 0.15; AME–AME 0.3; PME–PME 0.9. Opisthosoma. Dorsum black with white marks. Cardiac mark yellowish-white, with black dots. Venter yellow, covered with yellow setae. Spinnerets yellow, covered with white and black setae (Figs 45–46). Legs. Dorsal aspect: all coxae, trochanters, femora, patellae and tibiae light brown; metatarsi and tarsi I–II reddish-brown dorsally and black laterally, metatarsi and tarsi III–IV reddish-brown; all coxae, trochanters, femora and patellae covered with long and dense white setae and sparse short black setae; all tibiae and metatarsi and tarsi III–IV bear a fringe of sparse long black erect setae; metatarsi and tarsi I–II covered with dense short brown setae ventro-laterally and short white setae dorsally. Ventral aspect: all coxae, trochanters and femora yellow, covered with short and dense white setae and sparse long black setae; patellae yellow, each with a pair of grey parallel marks on proximal margins which are darker on legs I–II; tibiae I–II yellow proximally and grey distally (tibiae I darker); tibiae III–IV yellow; all tibiae and metatarsi and tarsi III–IV covered with dense short yellowish setae and long black protruded setae; metatarsi and tarsi I black, metatarsi and tarsi II dark brown and both covered with dense short light brown setae and sparse black protruded setae; metatarsi III–IV light brown (Fig. 47); tarsi of all legs with scopulae and spinules. Measurements and spination as in Tables 9–10. Palp. Palp as in Figs 50–56. Femora and patellae yellow and densely covered with short white setae. Tibiae yellow, ventral and lateral (especially prolateral) sides with dense fringe of long erect setae black proximally and white distally. Cymbium light brown, covered with short white setae and curly long light brown setae on its prolateral part. Median apophysis with fine and sharp lateral process; hook-shaped and acutely sharpened proximal extension and complemented with small tooth; median tooth of the median apophysis bifurcated consisting of a large, notched median claw complemented with small prolateral teeth and a prominent ventral flange (Figs 51, 54, 56); inner plate of the median apophysis narrow and prominent retrolaterally (Figs 50–51, 54). Conductor triangular, acutely pointed and bent at its tip. Synembolus with two convergent lamellae: apical lamellae apicalward-sloping straight, basal lamellae bent apicalward. Embolus gradually bent apicalward (Fig. 53). Female. See Logunov & Ponomarev (2020). Distribution. Russia (north-eastward of the Caucasus Major), eastern Azerbaijan, western Kazakhstan (Logunov & Ponomarev 2020), herein newly recorded from northeastern Iran (Fig. 57), which represents the southernmost limit of the species range.
