Kazakhithyas n. gen.

Diagnosis. Characters of the family Hydryphantidae ; idiosoma papillate, papillae blunt and at their base striated; frontal eye absent ( Fig. 3 View FIGURES 1 – 6 ); lateral eyes in capsules; glandularia platelets absent ( Fig. 1 View FIGURES 1 – 6 ); genital field with moveable flaps and three pairs of acetabula, not fused to these flaps ( Fig. 2 View FIGURES 1 – 6 ); palp chelate ( Fig. 5 View FIGURES 1 – 6 ); legs claws large, each claw with two combs, one long and one short, and without clawlet or claw blade ( Figs.7–8 View FIGURES 7 – 8 ).

Type species: Kazakhithyas pectinatus n. sp.

Etymology. The name is a combination of Kazakhstan and Thyas and is of male gender.

Remarks. The genus has the plesiotypical number of acetabula of the Hydryphantidae . However, the large claws with the two combs is unique for the Hydryphantidae . Only in Pseudohydryphantes and Ignacarus a claw with a comb is present (Gerecke pers. comm.), but these genera differ either in integument structure ( Pseudohydryphantes ) or the presence of a large dorsal plate ( Ignacarus ). Moreover, Pseudohydryphantes has the leg claws with two fine dorsal clawlets ( Di Sabatino et al. 2010).
