Habitus as in Fig. 28–30. Body brown to reddish-brown or black, sometimes with paler (yellowish or reddish) elytra and paratergites of abdomen; mouthparts, antennae and legs yellow-brown to brown (antennae in some specimens yellowish, or with paler antennomeres 1–3, femori (except apical portions) and tarsi).

Ocelli small or moderately large, distance between ocelli about as long as or slightly longer than distance between ocellus and posterior margin of eye. Punctation variable, fine or moderately large and deep, sparse or dense, usually denser and deeper in middle and sometimes finer and sparser on infraorbital portion. Antennomere 3 slightly longer and narrower than antennomere 2, 4–5 slightly narrower and shorter than 3, 6–8 slightly longer than 5, 9–10 slightly longer than 8, apical antennomre 1.3–1.7 times as long as 10.
Pronotum transverse, 1.4–1.8 times as broad as long, from widest middle or anterior third sharply narrowed toward short or moderately long subparallel mediolateral portions; middle portion without longitudinal depression, with transverse, shallow or moderately deep mediobasal depression. Punctation variable. moderately sparse, about as that or slightly larger than that on middle portion of head, or distinctly denser, larger and deeper, usually sparser in/or middle and mediobasal portions (some specimens without punctures in front of mediobasal depression).
Elytra slightly broader than long and slightly or significantly broadened posteriad, 1.6–1.7 times as long as pronotum. Punctation variable, about as that on pronotum or distinctly denser, larger and deeper, usually denser and coarser in parascutellar portion, and finer and sparser along suture.
Metatibia about twice as long as metatarsus.
Abdomen distincly narrower than elytra, with two large and transverse tomentose spots in middle of abdominal tergite IV (sometimes indistinct in some specimens).
Male. Pronotum wide, usually strongly convex. Profemuri and protarsomeres 1–4 distinctly widened. Apical margin of abdominal tergite VIII straight, rounded or slightly concave. Apical margin of abdominal sternite VIII concave. Median lobe very wide, from apical third strongly narrowed toward rounded or subacute apex; parameres slightly broadened apicad, reaching or exceeding apex of median lobe, with four short apical setae; internal sac weakly sclerotized, without visible structures except narrow and moderately short flagellum in middle or basal portion (Figs. 31, 33–36). Lateral aspect of the aedeagus as in Fig. 32.
Female. Pronotum moderately small, somewhat narrow, less convex. Profemuri and protarsomeres 1–4 narrow. Apical margin of abdominal tergite VIII straight or rounded. Apical margin of abdominal sternite VIII rounded.
Comparative notes. Based on the coloration, body length and the general shape of the body, G. (s.str.) convexicollis is similar to Central Asian G. (s.str.) kashmirensis, from which it can be distinguished by slightly more transverse pronotum and moderately narrow apical portions of the parameres. From all species of the convexicollis group it differs by the very wide median lobe.
Distribution. Geodromicus (s.str.) convexicollis is widely distributed in the Middle Asia, and known from Kazakhstan, Uzbekistan, Kyrgyzstan, Tajikistan and north-eastern Afghanistan (Fig. 37).
Bionomics. Specimens were collected at elevations from 700 to 3600 m a.s.l. and were taken from under stones near streams and rivers, or were sifted from the gravel, soil, drift and mosses. Some specimens were collected from under stones near snow spots. It was collected together with specimens of G. (s.str.) macrothorax in several localities of south-eastern Kasakhstan (Saryhastau Gorge, Kokjota Mnt., and Dzhungar Alatau). The localities in Chatkal Mts. (Uzbekistan) as in Figs. 38–39.
Remarks. Geodromicus convexicollis Luze, 1903 was originally described based on one specimen (“Nach einem männlichen Exemplare beschrieben.”) from Tashkent, Uzbekistan. Zerche (1992) studied the holotype and redescribed the species.
Bordoni (1984) based on the holotype and three paratypes described G. hauserianus from “Ost. Buchara, Tschiftschantan…”. It was synonymized by Zerche (1991) with G. (s.str.) convexicollis without the study of the type specimens. I studied the type specimens in NMW (see above) and confirmed this synonymization here.
Geodromicus cylindricus Tronquet, 1981 was originally described from “ Afghanistan: Baudi-I-Amir”. I studied the holotype and found that this specimen is conspecific with other specimens of G. (s.str.) convexicollis. Sketchy aedeagus provided by Tronquet (1981) is also similar to other studied specimens of G. convexicollis. Thus, I synonymized it with G. (s.str.) convexicollis.
