ABSTRACT. We provide herein the first report of a nest of Ceratina (Ceratinula) fioreseana Oliveira, 2020, a species that was recently described for the Cerrado domain. The nest was collected in a Passiflora edulis Sims (Passifloraceae) plantation in Minas Gerais State, Brazil and was built in a trap nest, a dry petiole of Cecropia pachystachya Trécul (Urticaceae). Within the nest there was a living female and a brood cell without partition containing a pupa, whose adult female emerged 28 days after pupation. Pollen analysis revealed the dominance of Emilia fosbergii Nicolson (Asteraceae) pollen grains, a weed recorded a few meters from the nest. The record of an adult female within the nest with a pupa and the absence of nest partition might suggest social behavior in this bee species.
