Key to the Colletes View in CoL species of Ethiopia

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 View FIGURE 14 b); terga without distinct apical hair bands ( Fig. 15 View FIGURE 15 b); large species (12–14 mm); S7 as in Fig. 15 View FIGURE 15 d................................................ C. latipes Friese View in CoL

- 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 View FIGURE 13 c); S7 as in Fig. 13 View FIGURE 13 d............. C. somereni Cockerell View in CoL

- 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 View FIGURE 11 b); S7 as in Fig. 11 View FIGURE 11 c......................................................................................... C. rothschildi View in CoL 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 View FIGURE 2 c........................ C. abessinicus Friese View in CoL

- Mesoscutal disc between punctures smooth and shiny......................................................... 5

5 Disc of T1 with abundant short appressed hairs ( Fig. 18 View FIGURE 18 b); S7 as in Fig. 18 View FIGURE 18 c................... C. microdontus Cockerell View in CoL

- Disc of T1 either without or with very few short appressed hairs................................................ 6

6 T1 apically narrowly brownish translucent ( Fig. 5 View FIGURE 5 b); S7 as in Fig. 5 View FIGURE 5 c.................... C. senkelensis Kuhlmann sp. n.

- T1 apically broadly yellowish translucent ( Fig. 9 View FIGURE 9 b); S7 as in Fig. 9 View FIGURE 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 View FIGURE 14 b); terga without distinct apical hair bands ( Fig. 14 View FIGURE 14 d); large species (12–14 mm)................................................................... C. latipes Friese View in CoL

2 Apical hair band of T1 broad and brightly orange, disc of T1 densely covered with short appressed hairs ( Figs 10 View FIGURE 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 View FIGURE 10 d)........................ C. rothschildi View in CoL Va cha l

- T1 densely covered with white to yellowish short appressed hairs ( Fig. 17 View FIGURE 17 d)................... C. microdontus Cockerell View in CoL

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 View FIGURE 1 d).................................. C. abessinicus Friese View in CoL

- T1 with very broad and complete apical hair band ( Fig. 6 View FIGURE 6 d)........................... C. aethiopicus Kuhlmann sp. n.

6 T1 apically narrowly brownish translucent; disc of T1 with very fine punctation ( Fig. 4 View FIGURE 4 d) … C. senkelensis Kuhlmann sp. n.

- T1 apically broadly yellowish translucent; disc of T1 with coarser punctation ( Figs 8 View FIGURE 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 View FIGURE 8 c)................................................................................................ C. langano Kuhlmann sp. n.

- Mesoscutum with fewer black hairs that are mostly restricted to the mesoscutal disc ( Fig. 12 View FIGURE 12 c)...... C. somereni Cockerell View in CoL
