Key to the Colletes View in CoL species of the European part of Russia

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 View FIGURE 6. a 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.

C. cunicularius (Linnaeus) View in CoL

- Facial fovea narrow, sometimes up to about twice as wide (cf. Fig. 5 View FIGURE 5. a 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
