Lachesana perseus View in CoL sp. nov. Figs 1D-F View Figure 1 , 2 View Figure 2 , 3F-J View Figure 3 , 4J View Figure 4 , 32 View Figure 32

Type material.

Holotype ♂ and paratype 1♂ (MHNG), Iran: Alborz Province: Eshtehard, Jaru, 35°44'N, 50°35'E, 10.2018 (A. Zamani).

Etymology.

The specific epithet refers to the legendary founder of Mycenae and of the Perseid dynasty in Greek mythology. Noun in apposition.

Diagnosis.

The new species differs from the similar L. kavirensis sp. nov. by the lack of spines in the proximal mesal part of the cymbium (vs. present; cf. Fig. 3C View Figure 3 and 3H View Figure 3 ) as well as by the RTA with the terminal half almost as wide as the tibia (vs. 1.5 times thinner). The shape of the RTA readily distinguishes this species from congeners in the region (stalk abruptly bent basally and tip gently curved; cf. Fig. 4J View Figure 4 and 4F-I View Figure 4 ).

Description.

Male (holotype). Habitus as in Figs 1D, E View Figure 1 , 2 View Figure 2 . Total length 10.50. Carapace 5.60 long, 2.60 wide at pars cephalica, 3.88 wide at pars thoracica. Eye sizes and interdistance of PMEs: AME: 0.19, ALE: 0.19, PME: 0.16, PLE: 0.19, PME-PME: 0.18. Carapace, sternum, labium, chelicerae and maxillae light brown. Chelicera (Fig. 1F View Figure 1 ) with dense, black setae and one promarginal tooth; fangs curved. Legs the same color as carapace, without annulations and with numerous spines. Abdomen pale, dorsally with a longitudinal dark stripe and several large spots. Spinnerets grayish, uniform in color. Measurements of legs: I: 16.42 (4.69, 2.02, 3.61, 3.56, 2.54), II: 15.48 (4.22, 2.01, 3.19, 3.53, 2.53), III: 16.25 (4.46, 1.96, 2.51, 4.66, 2.66), IV: 19.39 (4.87, 2.32, 3.29, 5.66, 3.25).

Palp as in Figs 3F-J View Figure 3 , 4J View Figure 4 . Tibial apophysis more than 1.2 times longer than tibia, widest part over 2 times wider than stalk; cymbium lacking spines in proximal mesal 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.

Female. Unknown.
