Genus Sestakovaia gen. nov.

Type species.

Sestakovaia hyrcania sp. nov.

Etymology.

The new genus is named after our colleague and friend, Anna Šestáková (Western Slovakian Museum, Trnava, Slovakia); the gender is feminine.

Diagnosis.

The new genus differs from other Liocraninae genera by the bent RTA (vs straight) with tip directed antero-dorsally. It differs from Mesiotelus Simon, 1897 by unmodified (not elongated) male chelicera, short palp (not longer than carapace), large and complex embolus (cf. Figs 9A, D , 10A with Fig. 11A ) and epigyne lacking fine anterior hood (cf. Chyzer and Kulczyński 1897: pl. 9, fig. 75 with Bosmans and El-Hennawy 2018: fig. 1).

Description.

Medium-sized, carapace ca 2.0 long, 1.5 wide, length of chelicera ca 1/3 of carapace length. Carapace and abdomen with distinct pattern. For details, see Chyzer and Kulczyński (1897) and the description below.

Comments.

Homology of anterior tegular apophysis (Aa) is not clear, as such structure is not known in other genera of the family.

Composition.

Sestakovaia hyrcania sp. nov. and S. annulipes ( Kulczyński, 1897), comb. nov.

Distribution.

Central Europe, Near East and northern Iran.
