Synaphosus shmakovi sp. n.

Figs 3 , 19‒21 , 51

Types: MONGOLIA: Khovd Aimag: holotype ♀ (ISEA), 36 km SW from Altai Village, Bodonchiyn-Gol River Valley, 45°46'N, 92°12'E, 1300 m, stony desert, 17.05.2015 (AF).

Etymology. The specific name is a patronym in honour of Alexander I. Shmakov (Barnaul, Russia) the director of the South-Siberian Botanical Garden (Barnaul) who helped to organize an expedition to Mongolia, during which the specimen treated here was collected.

Diagnosis. The new species belongs to the syntheticus group and differs from sibling S. palaearcticus by having no abdominal pattern, lack of prolateral spine on tibia II (cf. Table 1 ) and shape of epigyne. Epigyne in S. shmakovi sp. n. have more widely spaced epigynal openings, a thinner pocket with the hoods of the pocket not spaced (cf. Figs 19‒20 and 28‒29 ). In sibling species the copulatory openings are less spaced, the pocket is wider and the hoods are smaller and spaced by about their width. Synaphous shmakovi sp. n. differs from the similar S. makhambetensis ( Fig. 34 ) by the copulatory openings spaced by less than one diameter (more than one diameter in S. makhambetensis ) and the pocket equal in width to receptacle diameter (receptacles wider than pocket in S. makhambetensis ).

Description. Male unknown. Female. Total length 3.15. Carapace: 1.2 long, 0.88 wide. Eye sizes and interdistances: AME 0.04, ALE 0.04, PME 0.06, PLE 0.04, AME–AME 0.01, AME–ALE 0.01, PME–PME 0.04, PME–PLE 0.04, ALE–PLE 0.04; MOQ length 0.13, front width 0.13, back width 0.14. Carapace yellow-brown anteriorly, yellow posteriorly ( Fig. 3 ). Chelicerae, maxillae and labium light-brown. Sternum yellow. Legs and palps yellow. Abdomen and spinnerets daffodil, without pattern ( Fig. 3 ). Spination as shown in Table 1 .

Epigyne as in Figs 19‒21 , copulatory openings almond shaped, located above pocket, length of atria almost 3 times longer than width, atria separated by their width, pocket with deep hoods partly fused at the base; width of pocket subequal to septum width; width of endogyne subequal to span of atria.

Leg measurements.

Distribution. Known only from the type locality ( Fig. 51 ), Western Mongolia.
