Smit, Harry, 2016, A new hydryphantid genus from the Tien Shan Mountains of Kazakhstan (Acari, Hydrachnidia: Hydryphantidae), Zootaxa 4200 (2), pp. 324-326 : 324

Kazakhithyas n. gen.

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