Phylogeny and biogeography of the cleptoparasitic bee genus Epeolus (Hymenoptera: Apidae) and cophylogenetic analysis with its host bee genus Colletes (Hymenoptera: Colletidae)

The bee genus Epeolus Latreille (Hymenoptera: Apidae) consists of 109 species, which are known to be exclusively cleptoparasites of polyester (or cellophane) bees of the genus Colletes Latreille (Hymenoptera: Colletidae).

We present the most comprehensive phylogeny for Epeolus to date, based on combined molecular and...
