Type material.

Holotype ♂ (MHNG), Iran: Qom Province: Dasht-e Masileh, 34°47'N, 51°11'E, 11.2017 (M. Mirghazanfari).

Etymology.

The specific epithet is derived from ‘Kavir’, a Persian word for desert, referring to the occurrence of the species in the central deserts of Iran.

Diagnosis.

The male of L. kavirensis sp. nov. can be distinguished from the similar L. dyachkovi Fomichev & Marusik, 2019 by having a gently bent cheliceral fang (vs. bent over 90°, cf. Fig. 1C View Figure 1 and fig. 15 in Fomichev and Marusik 2019). The shape of the RTA is also different from other species of the region (stalk with a gentle curve ventrally and tip straightly pointed; cf. Fig. 4I View Figure 4 and Fig. 4F-H, J View Figure 4 ).

Description.

Male. Habitus as in Fig. 1A, B View Figure 1 . Total length 11.55. Carapace 5.80 long, 2.60 wide at pars cephalica, 3.75 wide at pars thoracica. Eye sizes and interdistance of PMEs: AME: 0.23, ALE: 0.20, PME: 0.17, PLE: 0.23, PME-PME: 0.14. Carapace, sternum, labium, chelicerae and maxillae light brown. Chelicera (Fig. 1C View Figure 1 ) with dense, black setae and one promarginal tooth; fangs gently curved, almost straight. Legs the same color as carapace, without annulations and with numerous spines. Abdomen pale, dorsally with a longitudinal dark stripe and several small spots. Spinnerets slightly lighter than abdomen, uniform in color. Measurements of legs: I: 15.49 (4.47, 1.88, 3.33, 3.29, 2.52), II: 15.03 (4.20, 1.79, 3.02, 3.50, 2.52), III: 15.78 (4.08, 1.96, 2.48, 4.71, 2.55), IV: 18.30 (4.58, 2.07, 3.20, 5.24, 3.21).

Palp as in Figs 3A-E View Figure 3 , 4I View Figure 4 . RTA long, over 1.2 times longer than tibia, its widest part less than 2 times wider than stalk; cymbium with 2 spines in mesal proximal part; bulb elongate, 1.3 times longer than wide; base of embolus large, 1/3 of the tegulum's length; embolus filamentous, lying in chute formed by conductor.
