Genera of the bee tribe Reedapini (Hymenoptera: Colletidae)

Those bees classified in the genera Reedapis Michener and Cephalocolletes Michener are discussed and organized into a new tribe, Reedapini Engel. In addition, three species formerly classified in Cephalocolletes are removed to two new genera: Lonchopriscus Engel, new genus, with the species Lonchopriscus crassipunctatus (Urban), new combination, and Cactocolletes Engel, new genus, for Cactocolletes isabelae (Urban), new combination, and C. rugatus (Urban), new combination. The tribe and its constituent genera are diagnosed, and a key is provided for the identification of the latter along with their included species
