description: Rhysodromus tikhmenevi Zamani & Marusik, sp. nov.
Figs 20C, 22A‒B
Type material. Holotype ♂ (ZMUT), IRAN: Sistan & Baluchistan Prov.: Zabol, 31°02'12"N 61°32'14"E, 480 m, 6.04.2020 (M. Enayatnia).
Etymology. This species is named after Pavel E. Tikhmenev (Magadan. Russia), a friend of YMM.
Diagnosis. The male palp of the new species resembles those of R. halophilus (Levy, 1977), R. timidus (Szita & Logunov, 2008) and R. xinjiangensis. It differs from R. halophilus by having a nearly indistinct, tiny tegular apophysis (Tg) and a conductor (Cd) that is as wide as it is long (vs. distinct tegular apophysis and a conductor that is longer than it is wide) (cf. Fig. 22A and Levy 1977: fig. 32). It differs from R. timidus by the tip of the retrolateral tibial apophysis (Ra), which is bent backward (vs. not bent), a meandering sperm duct within the embolus (vs. straight), and a tip of the embolus that is not sharply pointed (vs. pointed) (cf. Fig. 22A‒B and Szita & Logunov 2008: figs 33, 34). The male palp of R. tikhmenevi sp. nov. differs from that of R. xinjiangensis by having a thinner embolus, a shorter anterior loop (Al) of the sperm duct, and a bent tip of the tibial apophysis (vs. unbent) (cf. Fig. 22A‒B and Szita & Logunov 2008: figs 36, 37).
Description. Male (holotype). Habitus as in Fig. 20C. Total length 3.50. Carapace 1.60 long, 1.47 wide. Eye sizes: AME: 0.08, ALE: 0.08, PME: 0.06, PLE: 0.07. Carapace medially and marginally pale beige, laterally light brown, mottled and with paired white patches; chelicerae, sternum, labium and maxillae yellowish brown; sternum laterally and posteriorly mottled. Palps and legs yellowish brown, cymbium brown, legs mottled and with faint brown markings. Abdomen pale beige, dorsum with dark grey foliate pattern anteriorly and 2 converging dentate grey bands posteriorly. Spinnerets yellowish brown. Measurements of legs: I: 9.14 (2.51, 0.83, 2.34, 2.12, 1.34), II: 12.27 (3.23, 1.01, 3.24, 2.96, 1.83), III: 6.89 (2.04, 0.71, 1.71, 1.54, 0.89), IV: 7.53 (2.27, 0.71, 1.94, 1.72, 0.89).
Palp as in Fig. 22A‒B; tibia 1.25x longer than wide, retrolateral tibial apophysis (Ra) small, as long as wide, with pointed tip directed dorsally; cymbium elongate, ~ 2.3x longer than wide, tip long, ~ 1/3 of cymbial length, with 1 spine anteriorly from bulb and another prolaterally; bulb oval, ~ 1.8x longer than wide; sperm duct forming 3 distinct loops, posterior, anterior (Al) and prolateral; tegular apophysis (Tg) very small, almost indistinct, conductor located dorsal to embolus, with rounded tip, almost as wide as long; embolus with large base, tip slightly bent, not sharply pointed.
Female. Unknown.
Distribution. Known only from the type locality in Sistan & Baluchistan, southeastern Iran.
