Etymology. The name “ inornata   ” is translated from Latin as “without ornament” and indicates monochrome colouring of the species.

Bionomics. The species was found at night (22:00–23:00) on Juniperus oxycedrus   .

Diagnosis. See O. altimontana   sp. n.

Variability. The specimens of population from Beydağ differ from other populations by more dense elongate punctation on sides of pronotum and more robust body. Only near half of males among all populations have granules on metatibiae. The pronotum is variable in proportions and form.

Etymology. The name “ altimontana   ” is translated from Latin as high mountain.

Bionomics. The species was collected on Juniperus excelsa   at night (21:00–22:00).

Diagnosis. The new species is similar to O. inornata   sp. n., from which it differs by characters from the key. Additional differences of O. altimontana   sp. n. and O. inornata   sp. n. from close O. shokhini   sp. n.: anterior angles of pronotum not projected or weakly projected in females, straight or obtuse (anterior angles of pronotum in O. shokhini   sp. n. strongly projected, acute); punctation of pronotum moderately coarse and moderately dense, punctures round (punctation of pronotum in O. shokhini   sp. n. fine, not dense, punctures on sides of disc often elongated); body brown, black-brown or bicoloured, while O. shokhini   sp. n. has black body. Anterior tarsi of male not widened (protarsomeres 1–3 in O. shokhini   sp. n. are weakly widened).
