Males
The male of C. aethiopicus Kuhlmann sp. n. 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 Malar area elongate, much longer than width of base of mandible (cf. Fig. 14 b); terga without distinct apical hair bands (Fig. 15 b); large species (12–14 mm); S7 as in Fig. 15 d................................................ C. latipes Friese
- Malar area not elongate, shorter than width of base of mandible; at least T2–T5 with distinct apical hair bands; smaller species (<12 mm)........................................................................................... 2
2 Hind basitarsus posteriorly with a dense crest of long hairs (Fig. 13 c); S7 as in Fig. 13 d............. C. somereni Cockerell
- Hind basitarsus without a dense crest of long hairs........................................................... 3
3 T1 almost completely and densely covered with yellowish to orange short appressed hairs (Fig. 11 b); S7 as in Fig. 11 c......................................................................................... C. rothschildi Va cha l
- T1 without or only with few short appressed hairs, if densely covered with short appressed hairs than hairs white......... 4
4 Mesoscutal disc between punctures shagreened and matt; S7 as in Fig. 2 c........................ C. abessinicus Friese
- Mesoscutal disc between punctures smooth and shiny......................................................... 5
5 Disc of T1 with abundant short appressed hairs (Fig. 18 b); S7 as in Fig. 18 c................... C. microdontus Cockerell
- Disc of T1 either without or with very few short appressed hairs................................................ 6
6 T1 apically narrowly brownish translucent (Fig. 5 b); S7 as in Fig. 5 c.................... C. senkelensis Kuhlmann sp. n.
- T1 apically broadly yellowish translucent (Fig. 9 b); S7 as in Fig. 9 c....................... C. langano Kuhlmann sp. n.
Females
In some species-groups it can be difficult to reliably identify the females without a reference collection. This especially applies to worn specimens where the pilosity is partly or entirely rubbed off.
1 Malar area elongate, much longer than width of base of mandible (Fig. 14 b); terga without distinct apical hair bands (Fig. 14 d); large species (12–14 mm)................................................................... C. latipes Friese
- Malar area not elongate, shorter than width of base of mandible; at least T2–T5 with distinct apical hair bands; smaller species (<12 mm).......................................................................................... 2
2 Apical hair band of T1 broad and brightly orange, disc of T1 densely covered with short appressed hairs (Figs 10 d, 17d)... 3
- Apical hair band of T1 either broadly interrupted medially, or if complete hairs are white or slightly yellowish; disc of T1 at most with a few scattered short appressed hairs............................................................. 4
3 T1 densely covered with brightly orange short appressed hairs (Fig. 10 d)........................ C. rothschildi Va cha l
- T1 densely covered with white to yellowish short appressed hairs (Fig. 17 d)................... C. microdontus Cockerell
4 Mesoscutal disc between punctures shagreened and matt...................................................... 5
- Mesoscutal disc between punctures smooth and shiny........................................................ 6
5 T1 with narrow medially interrupted apical hair band (Fig. 1 d).................................. C. abessinicus Friese
- T1 with very broad and complete apical hair band (Fig. 6 d)........................... C. aethiopicus Kuhlmann sp. n.
6 T1 apically narrowly brownish translucent; disc of T1 with very fine punctation (Fig. 4 d) … C. senkelensis Kuhlmann sp. n.
- T1 apically broadly yellowish translucent; disc of T1 with coarser punctation (Figs 8 d, 12d); these species are difficult to dis- tinguish without reference material........................................................................ 7
7 Mesoscutum densely and extensively covered with a mix of yellowish-brown and black hairs (Fig. 8 c)................................................................................................ C. langano Kuhlmann sp. n.
- Mesoscutum with fewer black hairs that are mostly restricted to the mesoscutal disc (Fig. 12 c)...... C. somereni Cockerell
