Type species: Palaeomacropis eocenicus gen. nov. sp. nov.

Etymology: From the Greek Palaeo, meaning ‘old’, and Macropis referring to the similar contemporary bee genus (see Discussion).

Generic diagnosis: Female: glossa shorter than galea ( Fig. 2A, C View Figure 2 ); paraglossa densely hairy; labial palpal segments similar and cylindrical ( Fig. 2A, C View Figure 2 ); mandible with a very large preapical tooth on the upper margin ( Fig. 2A View Figure 2 ); one subantennal suture branching ventrally on the antennal socket ( Fig. 2C View Figure 2 ); facial foveae absent; vertex enlarged behind lateral ocelli ( Fig. 3A View Figure 3 ); basal width of propodeal triangle longer than four-fifths of basal width of propodeum; propodeal triangle bare; two submarginal cells, the second as long as the first ( Figs 3A View Figure 3 , 4B View Figure 4 ); second abscissa of Rs slanting and widely separated from 1m-cu ( Figs 3A View Figure 3 , 4B View Figure 4 ); apex of marginal cell pointed ( Figs 3A View Figure 3 , 4B View Figure 4 ); mid-basitarsus with dense plumose setae on inner and outer side ( Fig. 3B View Figure 3 ); trochanter with curved setae; no basitibial plate ( Fig. 3A View Figure 3 ); hind tibia and basitarsus with poorly developed scopa ( Fig. 2E View Figure 2 ); hind basitarsus narrower than tibia ( Fig. 2E View Figure 2 ); sterna with long, erect setae ( Figs 2D View Figure 2 , 4A View Figure 4 ). Male: unknown.
