Habitus as in Figs. 3–6 . Body yellow-brown to black (some specimens with darker head, yellow-brown or reddish ( Fig. 5 ) pronotum, sometimes with paler middle portion of elytra and paratergites, and sometimes with indistinct reddish spot on each elytron ( Fig. 6 )); mouthparts, antennae and legs yellow-brown to brown (apical segment of maxillary palpi usually paler, some specimens with yellowish antennomeres 1–2 or 1–3 and tarsi). Forebody without microsculpture, except for neck with very dense and coarse isodiametric sculpture, medioapical portion of pronotum in some specimens with traces of indistinct meshes and abdominal tergites with very dense transverse or isodiametric microreticulation.

Head 1.4 times as broad as long, frontal portion with slightly or strongly convex supra-antennal elevations, with deep and wide subtriangular or rectangular anterio-median depression; temples 1.5–1.8 times as long as longitudinal length of eyes; interocellar depression moderately narrow and deep, separated from infraorbital portions by deep anteocellar foveae (indistinct in some specimens) reaching about level of middle or apical third of eyes. Distance between ocelli slightly shorter or distinctly longer than distance between ocellus and posterior margin of eye. Punctation irregular and fine, denser in middle, sparser and sometimes slightly larger on infraorbital portions. Antennomere 2 1.4–1.7 times as long as basal antennomere, 3 distinctly longer than 2, 4–5 or 4–6 slightly shorter than 3, 7–10 broader and slightly shorter or longer than 6.

Pronotum 1.2–1.3 times as broad as long, from widest anterior third sharply narrowed toward moderately short subparallel laterobasal margins; middle portion without longitudinal depression, with shallow and sometimes indistinct or with moderately wide and deep transverse mediobasal depression; anterior margin slightly concave or rounded, distinctly narrower than straight posterior margin. Punctation dense, about as that or slightly larger and deeper than that on head, sparser and sometimes finer in medioapical (some specimens) or mediobasal portion (sometimes mediobasal portion in front of mediobasal depression without punctures).

Elytra 1.4–1.5 times as long as pronotum, slightly or widely broadened posteriad. Punctation about as that on pronotum, but distinctly sparser and sometimes finer in middle or along suture and usually denser and coarser in parascutellar portion (some specimens with slightly larger and deeper punctation than that on pronotum).

Metatibia about twice as long as metatarsus.

Abdomen narrower than elytra, with distinct, wide and large, transverse or oval tomentose spots in middle of abdominal tergite IV.

Male. Pronotum wide and convex. Profemuri and protarsomeres 1–4 wide. Apical margin of abdominal tergite VIII straight, rounded or sligthly concave.Apical margin of abdominal sternite VIII concave. Median lobe moderately wide, gradually or strongly narrowed toward subacute apex; parameres significantly broadened toward apical portions, exceeding apex of median lobe ( Figs. 16, 18 , 23 ) or slightly shorter ( Figs. 19–20, 22–24 ), with four moderately long apical setae; apical portion of median lobe with two narrow sclerotized structures; internal sac weakly sclerotized, with narrow and short or elongate flagellum ( Figs. 16–24 ). Lateral portion of the aedeagus as in Figs. 17 , 21 .

Female. Pronotum moderately narrow, slightly convex. Profemuri and protarsomeres 1–4 narrow. Apical margins of abdominal tergite VIII and sternite VIII straight or rounded.

Comparative notes. Based on the general shape of the body and the aedeagus, G. (s.str.) zwickianus is similar to G. (s.str.) bodemeyeri , from which it can be distinguished by the slightly broader pronotum and the abscence of the sclerotized parallel structures in the middle of the median lobe.

Distribution. Geodromicus (s.str.) zwickianus is distributed in Turkey and Iran ( Fig. 25 ).

Bionomics. Specimens were collected at elevations from 180 to 3800 m a.s.l. and were taken from under stones and gravel along river banks, and sometimes sifted from alluvial soils and gravel detritus. The locality of G. (s.str.) zwickianus in Qohrud Mts. as in Fig. 26 .

Remarks. Geodromicus (s.str.) zwickianus based on the holotype was originally described from “S.O.Anatolien: Ost Taurus bei Sürgü…”.

Geodromicus iranicus based on eight specimens was originally described from “ Iran … dans le Massif de l`Elbrouz”. During the study of the types and additional material from Turkey and Iran, I have not found sufficient morphological differences between types and other studied specimens. Thus, I synonymized G. iranicus with G. (s.str.) zwickianus .

The studied specimens from Turkey are usually with slightly darker body. The studied specimens from Zagros Mts. have slightly shorter and narrower pronotum with slightly larger punctation than that in other studied specimens. Despite that, shapes of aedeagi are slightly vary and have similar internal structures ( Figs. 16, 18–20, 22–24 ).
