A new species of Ceratina (Ceratinula) Moure, 1941, with notes on the taxonomy and distribution of Ceratina (Ceratinula) manni Cockerell, 1912, and an identification key for species of this subgenus known from Brazil (Hymenoptera, Apidae, Ceratinini)
A new species of the small carpenter bee, genus Ceratina (Ceratinula) Moure, from the Cerrado Biome in midwestern Brazil is described and illustrated. Ceratina (Ceratinula) fioreseana Oliveira, sp. nov. is easily distinguished from its congeners by the size of the facial maculations and the honey-yellow color of the legs and antennal scape, which distinguish it especially from Ceratina (Ceratinula) manni Cockerell, 1912, the most similar species in terms of facial maculation patterns. The geographic records of C. manni, here interpreted as endemic to the semiarid Caatinga region in northeastern Brazil, are presented, with new records for the Brazilian states of Piauí, Ceará and Bahia. A morphological description of both species is provided, including a comparison with the type specimen of C. manni from the state of Paraíba (Guarabira, formerly named Independencia). An identification key is provided for the described species of Ceratina (Ceratinula) recorded for Brazil according to Moure’s Catalogue of Neotropical Bees.
