Ancyloscelis apiformis (Fabricius, 1793)

Schaller, A. & Roig-Alsina, A., 2021, A revision of the bee genus Ancyloscelis (Hymenoptera: Apidae) in Argentina, Zootaxa 4980 (3), pp. 521-540 : 530

apiformis species group

Species of this group are small to medium sized, 4.2–9.5 mm long. The proboscides lack hooked hairs, and the males usually lack projections in front of the mid coxae, except A. romeroi and A. saltensis , with tuberculiform elevations. The vestiture is black and white to greyish in all the species ( Figs. 6A–D ); the mestasomal apical bands are white, usually interrupted on T1, and the female tibial scopa has black hairs dorsally and white hairs ventrally. There are no synapomorphies uniting the group, which may be proved to be paraphyletic relative to the ursinus group.
