Figs 1A-C , 3A-E , 4I , 32 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 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 and Fig. 4F-H, J ). Figure 1. Habitus and chelicerae of male Lachesana kavirensis sp. nov. ( A-C ) and L. perseus sp. nov. ( D-F ) A, B, D, E habitus, dorsal C, F chelicerae, ventral.

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.
