Males
The male of C. wacki is unknown. For the identification of males it is generally recommended and necessary for most species to dissect genitalia and especially S7. Due to variation in size and outer morphology the shape and size of S7 is the easiest and most reliable character for the identification of the majority of species. For all species S7 has been imaged at the same scale to facilitate rapid orientation and identification.
1 Metanotum medially raised and conspicuously convex, with an apical drop almost overhanging the horizontal part of propo- deum (cf. Fig. 6 c).................................................................................... 2
- Metanotum even or only slightly convex, in about the same level as the horizontal part of propodeum.................. 3
2 Head conspicuously elongate, malar area more than twice as long than width of base of mandible (cf. Fig. 28 c); S7 as in Fig. 18 e and T1-2 as in Fig. 18 f................................................................. C. nasutus Smith
- Head not elongate, malar area much shorter than width of base of mandible; S7 as in Fig. 18a and T1-2 as in Fig. 18 b....................................................................................... C. albomaculatus (Lucas)
3 Facial fovea broad, about 3-4 times as wide as width of antennal flagellum (cf. Fig. 5a); metasomal terga without distinct api- cal hair bands (Fig. 18 d); large species (11–15 mm); S7 as in Fig. 18 c...................... C. cunicularius (Linnaeus)
- Facial fovea narrow, sometimes up to about twice as wide (cf. Fig. 5 b) but usually only as wide as antennal flagellum or nar- rower; metasomal terga with apical bands or at least apicolateral hair patches; species usually smaller.................. 4
4 Apical hair fringe of S5 medially with hairs more than twice as long than laterally (Figs 9 b, d, f)..................... 5
- Apical hair fringe of S5 without distinctly longer hairs medially................................................ 7
5 Elongate part of apical hair fringe of S5 narrow (Fig. 9 d); punctation on the discs of T1-2 more dispersed (Fig. 10 b); S7 broader (Fig. 9 c)..................................................................... C. caspicus Morawitz
- Elongate part of apical hair fringe of S5 broad (Fig. 9 b, f); punctation on the discs of T1-2 more dense (Fig. 10a, c–d); S7 nar- rower (Fig. 9a, e)..................................................................................... 6
6 Punctation on the discs of T1-2 fine (Fig. 10a); elongate part of apical hair fringe of S5 denser (Fig. 9 b); S7 as in Fig. 9a .................................................................................... C. anceps Radoszkowski
- Punctation on the discs of T1-2 coarser (Fig. 10 c–d); elongate part of apical hair fringe of S5 more dispersed (Fig. 9 f); S7 as in Fig. 9 e............................................................................. C. maidli Noskiewicz
7 S6 with a pair of apical grooves (Fig. 25 e).................................................................. 8
