description: Key to the species of puella -group in a broad sense
The following simple key may be proposed for the representatives of the puella -group in a broad sense in the Caucasus.
1. Males.............................................................................................. 2
- Females............................................................................................ 5
2. Paraproct spine directed caudad and as long as 5/6 of S10 length in lateral view; pronotum hind lobe almost straight, with scarcely traced lateral depressions and a central notch........................................ C. australocaspicum
- Paraproct spine more or less slanting as to some extent inclining up, not longer than 2/3 of S10 length in lateral view; pronotum hind lobe more or less trilobate.......................................................................... 3
3. Depression between paraproct spine and prominence scarcely expressed, not deeper than rounded rectangular; spine thick; cercus trunk in lateral view slanting as a curve, without expressed apex.................................... C. puella
- Depression between paraproct spine and prominence deep, prominence process-like; cercus trunk in lateral view has an expressed apex....................................................................................... 4
4. Paraproct spine directed more up than behind, so that incision between it and prominence broad; cercus trunk in dorsal view of almost even width.......................................................................... C. pulchellum
- Paraproct spine directed more behind than up, so that incision between it and prominence narrower; cercus trunk in dorsal view broadening................................................................................. C. ponticum
5. Pronotum hind lobe almost straight, with a negligible central notch............................. C. australocaspicum
- Pronotum hind lobe more or less trilobate................................................................. 6
6. Pronotum hind lobe with three strong lobes and deep depressions between them........................ C. pulchellum
- Pronotum hind lobe with smooth lobes and depressions between them........................................... 7
7. Pronotum hind lobe with very smooth lobes of about the same size, with symmetrical shallow depressions between them, S8 black optionally with small blue markings........................................................... C. puella
- Pronotum hind lobe with better expressed lobes, with the central one larger, and asymmetrical incisions between them; S8 largerly blue................................................................................ C. ponticum
