Abdominal ventrite 5 with one deep round and 2 weak elongate depressions, weakly pubescent in apical part, with long hairs only on margin.

Etymology. Latin “ evestigata ” is translated as “found”, “found out”. This refer to the fact that specimens of the new species were discovered among those of similar O. torosica .

Bionomics. Adult specimens of this species were collected on trunks of Cedrus and Abies between 20:00 and 23:00.

Diagnosis. The new species is similar to O. torosica and O. zoltani , but differs from them by the following characters: anal abdominal ventrite with dense (in males) or not dense (in females) long hairs on surface or apex (both other species have bare anal ventrite, or regularly covered by simple setae in O. zoltani ); anterior angles of pronotum visibly projected (anterior angles in O. torosica and O. zoltani not projected); metatibiae of male are with only simple setaetion on inner side (they are densely pubescent by long suberected hairs on inner side in O. zoltani and O. torosica ).

Some populations have mucron on elytral apex. Lateral margins of elytra sinuate or not sinuate near apex (accordingly mucron present or absent). Ventral side of body bare. Abdominal ventrites 1–4 with fine and sparse punctation. Ventrite 1 without hair brush; ventrite 5 convex, with finer and denser punctation, without pubescence, with shallow longitudinal depression apically, completely beaded. Legs.

Each trochanter with one long setae.

Description, female. Body length 10–14.7 mm, body width 4.2–6.2 mm. Body more robust. Pronotum widest at middle (rarely behind middle). Abdominal ventrite 5 not convex, bare, with not deep round depression apically.

Etymology. The name “ torosica ” derives from Turkish ‘Toros Dağları’ (Taurus Mountains).

Bionomics. The species was found at night (20:00–1:00) on trunks of Juniperus excelsa .

Diagnosis. Odocnemis torosica sp. n. is similar to O. zoltani , from which it differs by the following characters: metaventrite and abdominal ventrites bare (they are regularly pubescent with short recumbent hairs in O. zoltani ); body slender (at least in males), monochrome, dark-brown (body of O. zoltani wide, robust, brown, in male often bicoloured: pronotum red-brown, head and elytra brown); metatibiae of male usually without teeth or granules, rarely (subspecies O. t. subangulata sp. n.) with teeth (metatibiae of male in O. zoltani with 4–6 distinct teeth). Differences between the new species and O. evestigata sp. n. can be found in the diagnosis of the latter.
