Type Material. Holotype ♀ ( ZMUT), IRAN: Bushehr Prov.: Asaluyeh, near Asaluyeh Airport , 27°28'N 52°36'E, 27.I.2016 (A. Zamani).

Etymology. The specific epithet refers to Liyan, an Elamite port on the Persian Gulf, located near the modern-day city of Bushehr, Iran.

Diagnosis. The new species is similar to C. hungaricus (Balogh, 1935) – known from France to Greece and Russia (Europe, Caucasus) – by having a uniformly light colored body and a similarly caret-shaped epigynal fovea, but differs by much larger size (6.4 vs. 1.9), as well as by having an epigynal scape (Sc) (vs. hood), converging anterior parts of the copulatory ducts (vs. diverging), and the presence of accessorial glands (Ag) (vs. absent) (cf. Fig. 6A–C and Kovblyuk & Nadolny, 2010: figs 8, 10–13).

Description. Female (Holotype). Habitus as in Fig. 6A. Total length 6.40. Carapace 2.67 long, 2.00 wide. Eye sizes: AME: 0.12, ALE: 0.11, PME: 0.11, PLE: 0.08. Carapace, chelicerae, maxillae, labium and sternum yellowish brown. Legs slightly lighter than carapace, without annulations. Chelicerae each with 5 pro- and 3 retromarginal teeth. Abdomen light beige, without any patterns. PMS pale, ALS and PLS light brown. Measurements of legs: I: 7.67 (2.14, 1.37, 1.72, 1.46, 0.98), II: 6.33 (1.81, 1.11, 1.36, 1.26, 0.79), III: 5.46 (1.56, 0.84, 1.05, 1.28, 0.73), IV: 7.98 (2.14, 1.19, 1.73, 2.01, 0.91).

Epigyne as in Fig. 6B–C; epigynal plate slightly longer than wide, with small, weakly sclerotized subtriangular scape (Sc); fovea caret-shaped, posterior margin strongly protruding anteriorly; copulatory opening (Co) located anteriorly on protrusion; copulatory ducts forming X-shaped figure; pair of elongate accessorial glands (Ag) located at mid-part of copulatory ducts; receptacles globular, spaced by one radius.

Male. Unknown.

Distribution. Known only from the type locality in Bushehr Province, southern Iran.
