Synaphosus sp.: Marusik & Logunov 1999: 240 (in part).

Types. MONGOLIA: Bayankhongor Aimag: holotype ♀ ( ZMMU) Bayanlig Somon, Bor-Tolgoi, 44°06'N, 100°56'E, 1400 m, pitfall traps in desert and close to bushes, sweeping/shaking bushes ( Amygdalus , Caragana , Zygophyllum ), 2‒4.06.1997 (YM).

Etymology. The species name derives from the type locality.

Diagnosis. The new species belongs to the syntheticus -group and is most similar to S. shmakovi sp. n., S. syntheticus and S. makhambentensis . It is well different from S. syntheticus by the narrow space between the hoods of the pocket and the copulatory ducts (cf. Fig. 35 and fig. 15 in Ovtsharenko et al. 1994). Synaphosus mongolicus sp. n. differs from S. shmakovi sp. n. by the smaller copulatory openings and sperm ducts stretching anteriorly over hoods of the pocket (cf. Figs 35 and 19‒21 ). The new species differs from S. makhambentensis by the shorter hoods of the pockets, and copulatory ducts extending over pocket (cf. Figs 34 and 35 , anterior loops of copulatory ducts located posteriorly from pocket in S. makhambetensis ).

Description. Male unknown. Female. Total length 3.65. Carapace: 1.3 long, 0.98 wide. Eye sizes and interdistances: AME 0.07, ALE 0.06, PME 0.07, PLE 0.06, AME–AME 0.01, AME–ALE 0.0, PME–PME 0.04, PME–PLE 0.04, ALE–PLE 0.03; MOQ length 0.16, front width 0.14, back width 0.17. Carapace yellow-brown anteriorly, yellow posteriorly. Chelicerae, maxillae and labium light-brown. Sternum yellow-brown. Legs and palps yellow-brown, tibiae-tarsi darker than other segments. Abdomen and spinnerets cream-coloured. Spination as shown in Table 1 .

Leg measurements.

Epigyne as in Figs 35 a,b, pocket with hoods touching each other, copulatory opening small, closely spaced, located over (anteriorly) of pocket; copulatory ducts long with several loops, most of loops directed vertically, some loops stretching over pocket.

Distribution and note. Known only from the type locality ( Fig. 51 ). The holotype female was collected in the same locality and habitat as S. ovtsharenkoi sp. n. It was recorded together with S. ovtsharenkoi sp. n. as " Synaphosus sp." by Marusik & Logunov (1999) from Mongolia.
