Genus Rhabdocupes Ponomarenko, 1966

Type species: Rhabdocupes longus Ponomarenko, 1966 .

DIAGNOSIS. Beetles with narrow bodies, body length to width ratio distinctly more than 2. Integument with tubercles of small or medium-size, uniform in shape ( Fig. 29 ). Head rectangular or trapezoid. Head length in front of eyes is equal or slightly exceed eye longitudinal diameter; head width to eye transverse diameter ratio is 4–5. Pronotum rectangular, not narrowing or only slightly narrowing anteriorly, not narrowing posteriorly; pronotal anterior margin weakly concave, its anterior angles not protruding forward or protruding only slightly; pronotal disc with rectangular median protuberance. Elytral epipleural margin straight, veins 2 and 3 follow epipleuron, form straight parallel rows, not merging together before reaching elytral apex. Epipleuron almost not narrowing towards the apex or narrowing slightly and gradually at elytron basal half (distinctly narrowing only in Rh. minisculus ). Elytral cells are round or oval-shaped.
