Pronotum trapezoidal, widest at apical quarter ( Figs 7A, F , 9C )................................................ 2 – Pronotum oval ( Figs 5B , 1B, C , 3A, B ) or cordiform ( Figs 5A, D, E ), widest at middle ( Fig. 3B ), slightly ahead of middle ( Figs 1B, C ) or rarely at anterior third ( Fig. 5D ), but in this case pronotum very long, body slender ( Fig. 5D ), apical piece of aedeagus strongly widened ( Fig. 6C )............................................................................. 3 2. Border of elytral base wider than pronotum ( Figs 7A, B, F ). Mesoventrite with transverse deep wrinkles ( Fig. 7E ). Puncturation of head and pronotum fine and sparse, but much coarser, well visible ( Fig. 7F )............................ C. lopatini – Border of elytral base narrower than pronotum or with the same width ( Fig. 9C ). Mesoventrite with separate bracket-like fovea ( Fig. 9D ). Puncturation of head and pronotum extremely fine and sparse, almost imperceptible ( Fig. 9C )................................................................................................ C. khudaybergani sp. n. 3. Elytral border complete, reaching scutellar shield ( Figs 5A, B, D ). Male protibiae (dorsal view) strongly bent at apical third ( Fig. 6A ). Antennomere 1 coarsely and densely punctured ( Fig. 5E ) Body length 9–10 mm .................. C. selevini – Elytral border shortly interrupted in middle, not reaching scutellar shield ( Figs 1A–C , 3A–C ). Male protibia (dorsal view) weakly bent along entire length ( Figs 1A, B , 4B ). Antennomere 1 finely and sparsely punctured ( Figs 2A , 3E )........... 4 4. Lateral margin of eyes very weakly rounded, almost straight, lateral margin of head at junction of eye and temple angular ( Fig. 2A ). Intercoxal process of abdominal ventrite 1 between metacoxae transversely impressed at apex, border interrupted only at middle, border lines curved towards the middle ( Fig. 1F ). Metaventrite and abdominal ventrite 1 with simple punctures along coxae, very rarely with with several hardly visible bracked-like punctures ( Fig. 1F ). Male aedeagus – Figs 2C, D . Body length 7.5–9.4 mm ............................................................................... C. jachontovi – Lateral margin of eyes evenly moderately rounded, lateral margin of head at junction of eye and temple not angular ( Fig. 3E ). Intercoxal process of abdominal ventrite 1 between metacoxae not transversely impressed at apex, not bordered apically, border lines straightly interrupted at apex ( Fig. 3D ). Metaventrite and abdominal ventrite 1 coarsely and densely punctured with rasp-like foveae along coxae ( Fig. 3D ). Male aedeagus – Figs 4D, E................................ C . ustyurtensis sp. n.
