Type material. Holotype, ♂: Lebanon, Bekaa El Gharbi, Machghara, 33°37ʹN 35°46ʹE, viii. 2017 (E. Nasir-Eddin leg.) (ZIN). Paratypes. 1♀ and 1♂: the same data as holotype (JHAC).
Description. Male. Body length 11.9–13.2 mm, width 3.1–4.2 mm. Body slender, brown, moderately shiny, elytra more dull. Head widest at eye level. Eyes large, convex. Ratio of head width at eyes to distance between eyes: 1.83–1.92. Anterior margin of epistoma weakly widely emarginated. Genae strongly rounded in basal half and very weakly rounded in anterior part; outer margin of head between gena and epistoma with distinct obtuse emargination. Punctation of head coarse and dense (puncture diameter 1.5–2 times as long as interpuncture distance), punctures round. Antennae long (reaching almost half of elytral length), with 4 apical antennomeres extending beyond base of pronotum.
Pronotum subcordate, very weakly transverse (1.06–1.07 times as wide as long), widest at middle or slightly before middle, 1.36–1.37 times as wide as head. Lateral margins weakly rounded, weakly sinuate basally. Anterior margin weakly emarginate, base widely rounded. Anterior angles right, with narrowly rounded apex; posterior angles weakly obtuse, with distinct apex. Lateral margins narrowly beaded, anterior margin and base with wider and more flattened bead. Disc evenly convex, only near basal angles slightly flattened. Punctation of disc moderately coarse and dense, the same or sparser than on head. Prothoracic hypomera not flattened along outer margin, finely rugose in middle and smooth along margins. Prosternum depressed along coxae. Prosternal process weakly convex.
Elytra elongate (2 times as long as wide), widest slightly after middle, 2.82–2.96 times as long and 1.27 × as wide as pronotum, 1.4 × as wide as head. Elytral apical quarter strongly elongate, but lateral margins not emargin- ated and not formed mucron. Strial punctures round or weakly elongate, merged by narrow furrow. Elytral intervals weakly convex in basal two thirds and flat in apical third, with very fine and sparse poorly visible punctation; intervals with sparse distinct tubercles, especially at apex and on sides; 5th and 7th intervals with tubercles on all length. Epipleural carinae wide (completely visible dorsally), reaching sutural angles of elytra; epipleura with inner narrow carina not reaching elytral apex; epipleural apex with dense pubescence. Mesoventrite with dense and coarse punctation. Mesepisterna, mesepimera, metepisterna and metaventrite with very fine and very sparse punctures. Intercoxal process of metaventrite coarsely wrinkled.
Abdominal ventrites with fine and sparse punctation, ventrites 1–3 smooth and finely wrinkled on sides; ventrite 1 without hair brush; ventrite 5 with weak and wide round depression in apical half, without dense pubescence, completely beaded. Apical piece of aedeagus curved upward, with unusual ball-like thickness et apex.
Legs long and slender. Trochanters with acute projected tooth near apex and single long seta. Protibiae straight (on outer margin) and bisinuate on inner side, with 3–4 large and several small teeth on inner side. Mesotibiae bent inward, with 4–10 small teeth on inner side. Metatibiae straight, with or without (in small specimens) small teeth and tubercles on inner side. Protarsi weakly widened.
Female. Body robust, pronotum more transverse (1.2 times as wide as long), elytra 1.8 times as long as wide, with weak mucron at apex. Antennae shorter, with only three apical antennomeres extending beyond base of pronotum, reaching quarter of elytral length. Abdominal ventrite 5 with more deep depression. Legs without teeth on inner side. Body length 12.6 mm, width 4.5 mm.
Differential diagnosis. This new species is similar to O. praelonga by the presence of a mucron in females and to O. moabitica by the presence of a tooth and granules on the inner side of metatibiae (at least in large specimens). Odocnemis evae sp. nov. differs from these both species by the shiny body, the presence of tooth on outer margin of male pro- and mesotrochantes and the structure of aedeagus (see differences from other species in the key).
Etymology. Patronymic, dedicated to the collector of the new species, Eva Nasir-Eddin (Machghara, Lebanon).
