Shafaie, Sepideh, Nadolny, Anton A. & Mirshamsi, Omid, 2022, A new species of Lycosa and three new species and a new record of Karakumosa from Iran (Araneae, Lycosidae), Zootaxa 5120 (4), pp. 501-522 : 502-505

Lycosa soboutii sp. n.

Figs 1–7 , 57

Types. ♀ Holotype (ZMFUM-LYC-0011) and 1 ♀ paratype (ZMFUM- LYC-0012), IRAN, Zanjan Province: Dandi City , 36.56°N, 47.59°E, 1631 m a.s.l., 20. Sep. 2014, A. Mahmoudi leg.

Etymology. The species name is a patronym, honoring the contemporary Iranian theoretical physicist, Yousef Sobouti (b. 1932, in Zanjan, Iran).

Diagnosis. The females of the new species resemble those of L. aragogi ( Nadolny & Zamani 2017: figs 1– 2) and L. macrophthalma ( Nadolny & Zamani 2020: figs 4, 7–11) in the shape of the epygine, but differ in the following characters: 1) pentagonal septum with 1.5 width/length ratio (vs. rectangular septum with 0.8 ratio in L. macrophthalma and conical septum with 0.7 ratio in L. aragogi ); 2) a triangular prominence in the base of septum ( Fig. 5 , vs. absent in L. aragogi and L. macrophthalma ); 3) pointy, ear-shaped hood edges ( Fig. 5 , vs. rounded in L. aragogi and L. macrophthalma ); 4) stalk of spermatheca long, the head of the spermatheca reach the anterior side of the copulatory duct ( Figs 6–7 , vs. stalk comparably short, the head does not reach the beginning of duct in L. aragogi and L. macrophthalma ). The three species also differ in spination ( Table 1 ; see also Nadolny & Zamani 2017, 2020).

Description. Female (holotype). Total length 19.95. Carapace 9.6 long, 6.6 wide.

Prosoma. Carapace reddish-brown, with a wide median longitudinal band and three triangular spots of white and black setae ( Fig. 1 ); marginal stripes yellow, wide and continuous with distinct reddish-brown spots; black around all eyes ( Figs 3–4 ). Sternum uniformly black, covered with black setae. Chelicerae dark brown, proximally covered with long white setae, distally with black setae. Endites dark brown, pale apically. Clypeus yellow, covered with black setae. Labium dark brown, covered with black setae ( Figs 2–3 ).

Eyes. Sizes and interdistances: ALE 0.3; AME 0.3; PLE 1.2; PME 1.2; ALE–AME 0.2; AME–AME 0.2; PME– PME 1.05.

Opisthosoma. Dorsum with several yellow spots, each spot with black dots dorsally. Cardiac mark yellow. Venter black, covered with black setae. Spinnerets long and yellow ( Figs 1–2 ).

Legs. Dorsal aspect: coxae and trochanters entirely black. Femora I–IV yellow, with two longitudinal, parallel grey stripes distally; patellae yellow, with grey triangular spots laterally, prolateral spots larger and darker; all tibiae yellow at the proximal halves and light brown at the distal halves, with grey triangular spots on marginal edges, spots on legs III–IV larger and darker. Metatarsi light brown, with a black ring distally; tarsi reddish-brown, with long setae on tarsi I and III. Ventral aspect: coxae, trochanters and patellae black. Femora entirely yellow; tibiae yellow, with grey proximal and distal rings, darker rings in tibiae III–IV. Metatarsi and tarsi light brown, with spinules; metatarsi and tarsi I–II with scopulae. Measurements and spination as in Tables 1–2 .

Palp. Palp as in Figs 1–2 . Palps light brown, covered with white setae. Black setae covered tibiae laterally and tarsi posteriorly.

Epigyne. Epigyne and vulva as in Figs 5–7 . Septum 5 long, 4.5 wide. Septum slightly longer than wide. Septum crest-shaped, with a triangular prominence pointed proximad; posterior side of septum rounded; septal pedicle elongated to its posterior edge. One pair of hoods situated laterally; both hood edges (long) and shaped as pointed ears. Spermathecal head spherical, leading via stalk of spermatheca to small spermathecal base. Spermathecal head 3 times wider than spermathecal base; stalk of spermatheca horseshoe-shaped and convergent. Copulatory ducts look like a fisted hand, situated along spermathecal base.

Male: Unknown.

Distribution. Known only from the type locality ( Fig. 57 ).
