Key to the females of the Colletes albomaculatus species-group

Females of this species-group are easily recognized from all other Palaearctic Colletes by a combination of punctate tegulae and a medially raised and conspicuously convex metanotum that has an apical drop almost overhanging the horizontal part of the propodeum ( Fig. 10 ). Colletes nasutus SMITH might be placed here too, but has a distinctly elongate face (genae about 2 times longer than width of base of mandibles) that is very different from the more round or oval head shapes of the other species (e.g. Figs 1, 3, 5 ).

1 Punctation of vertex between lateral ocellus and eye sparse and more dispersed (i = 1- 2d), between punctures polished and shiny; apical margin of T1 slightly and gently depressed.............................................................................................................................2

- Punctation of vertex between lateral ocellus and eye very dense (i <0.5d), punctures touching each other; apical margin of T1 sharply truncate and deeply depressed ( Figs 2, 4, 6 ) .....................................................................................................................................3

2 Facial fovea broader than width of antenna; disc of T1 very coarsely and densely punctate (i = 0.5d), punctures on apical margin of T1 much finer, only about 1/10 of the size on disc .................................................................................. C. dorsalis MORAWITZ

- Facial fovea narrow, less than half the width of antenna; punctation of disc of T1 much finer and more dispersed (i = 1-2d), punctures on apical margin of T1 more similar in size, about 1/3 to 1/4 of the size on disc...................................... C. albomaculatus (LUCAS)

3 Apical depression of T1 narrow, about the width of the antenna, punctation on disc of T1 very coarse ( Fig. 4 ); head as in Fig. 3 ......................................... C. punctatus MOCSARY

- Apical depression of T1 broader, slightly wider than width of the antenna, punctation on disc of T1 finer ( Figs 2, 6 )..............................................................................................4

4 Apical depression of T1 polished and shiny, without punctures, punctation on disc of T1 more dispersed (i = 0.5-1d), shiny between punctures ( Fig. 6 ); head broader than long ( Fig. 5 )....................................................................................... C. alfkeni NOSKIEWICZ

- Apical depression of T1 slightly shagreened, with very fine and dispersed punctation, punctation on disc of T1 very dense (i <0.5d), matt ( Fig. 2 ); head longer ( Fig. 1 ) .............. ............................................................................................................... C. jansmiti nov.sp.
