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.

Ceratina（Ceratinula）Moure的新物种，1941年，有关Ceratina（Ceratinula）manni Cockerell的分类学和分布的注释，1912年，并且是从巴西已知的该亚属的物种的识别码（Hymenoptera，Apidae，Ceratinini）

描述并说明了来自巴西中西部Cerrado Biome的一种新的小型木匠蜜蜂Ceratina（Ceratinula）Moure属。塞拉蒂娜（Ceratinula）fioreseana Oliveira，sp。十一月 通过面部斑纹的大小，腿部和触角花蜜的蜜黄色的颜色很容易与同类动物区分开来，这尤其使其与1912年的Ceratina（Ceratinula）manni Cockerell区别开来。 。本文介绍了曼尼梭菌的地理记录，这里被解释为巴西东北部半干旱的卡廷加地区的特有物种，并提供了巴西皮奥伊州，塞阿拉州和巴伊亚州的新记录。提供了这两种物种的形态学描述，包括与帕拉伊巴州（瓜拉比拉州，原名Independencia）。根据Moure的新热带蜜蜂目录，为巴西记录的描述的Ceratina（Ceratinula）物种提供了识别码。
