Description, male. Body length 11–11.5 mm, body width 4–4.1 mm. Body slender, dark-brown, with dull shining; head and pronotum more shining than elytra. Head widest at level of eyes. Eyes large, weakly convex. Ratio of head width at eyes to distance between eyes: 1.75. Genae strongly rounded. Lateral margin of head between gena and clypeus with obtuse emargination. Surface of head with weak longitudinal depression in anterior half of frons. Punctation of head moderately coarse and moderately dense; diameter of punctures subequal to distance between them. Punctation in head depressions finer and denser. Antennae long (reaching 1/3 of elytral length), with 4 antennomeres extending beyond base of pronotum; 3rd antennomer 3.4 × as long as 2nd and 1.54 × as long as 4th. Pronotum transverse (1.24 × as wide as long), widest at middle, 1.4 × as wide as head. Lateral margins of pronotum weakly rounded, sinuate near base. Anterior margin widely emarginated; base weakly rounded. Anterior angles straight, weakly projected, narrowly rounded on apex; posterior angles straight, distinct on apex. All margins of pronotum narrowly beaded. Disc regularly weakly convex. Punctation of disc fine, not dense; diameter of punctures 1.5–2 × as short as distance between punctures, punctures round. Hypomera not flattened on margins, with fine longitudinal wrinkles. Elytra weakly convex, widest at middle (1.65 × as long as wide), 1.3 × as wide and 2.7 × as long as pronotum, 1.9–2 × as wide as head. Strial punctures merged in entire furrows. Elytral intervals flat, with fine distinct punctation; apical elytral part with very small tubercles. Epipleural carina completely visible dorsally; epipleura reaching sutural angle of elytra, not flattened (epipleuron thickened) on apex. Narrow inner carina of epipleura not reaching elytral apex. Elytra without mucron. Ventral side of body (meso- and metaventrite) bare. Abdominal ventrites covered with short recumbent setae. Ventrite 1 without hair brush; ventrite 5 without dense pubescence of long recumbent hairs, without distinct depression, completely beaded. Legs long and narrow. Femora smooth and shining on inner side, not pubescent. Protibiae weakly bent, with 7 large and 5–6 small teeth on inner side; mesotibiae straight, with 3 large teeth and some small granules; metatibiae straight, with granules on inner side and simple (not dense and long) pubescence of recumbent hairs. Each trochanter with one long setae.

Redescription, female. Body length 11–12 mm, body width 4.3–4.5 mm. Body wider. Pronotum more transverse (1.65 × as wide as long). Elytra wider (1.6–1.64 × as wide as long), widest behind middle. Margins of elytra weakly sinuate near base. Antennae shorter, reaching 1/5 of elytral length, 3 apical antennomeres extending beyond base of pronotum.

Etymology. The species is named in honour of Egecem Keskin, the son of the second coauthor.

Bionomics. The species is distributed in high mountain steppe (2314 m) and inhabits stones with lichens (collected at night).

Note. The species was described by one unusual small female as Armenohelops   , but must be transferred to Odocnemis   after the study of additional material (including males) from the type locality.
