We describe a new species of the bee genus Centris, Centris (Centris) byrsonimae Mahlmann & Oliveira sp. n., whose name has appeared as a nomen nudum in the literature since 1985. Further, a new species group of Centris s.str. is proposed, the pulchra group, based on morphological characters, which comprises the species Centris pulchra Moure, Oliveira & Viana, 2003 and Centris byrsonimaesp. n..Based on information from specimen labels studied and data from the literature, a list of plant species visited by the pulchra group is presented. The male genitalia and hidden metasomal sterna 7 and 8 of Centris pulchra are described for the first time. Typographic errors pertaining to the paratype labels reported in the original description of Centris pulchra are corrected. One female paratype of Centris pulchra is designated herein as a paratype of Centris byrsonimaesp. n. An updated list of species of Centris s.str. from northeastern Brazil is provided including references about geographic distributions as well as an identification key to the pulchra species group.
我们描述了蜜蜂属Centris的一个新物种，即Centris (Centris) byrsonimae Mahlmann & Oliveira sp. n.，自1985年以来其名称在文献中一直作为裸名出现。此外，基于形态特征提出了Centris狭义的一个新物种组，即pulchra组，它包括2003年的Centris pulchra Moure、Oliveira & Viana以及Centris byrsonimae sp. n. 基于所研究标本标签的信息和文献数据，列出了pulchra组所访植物物种清单。首次描述了Centris pulchra的雄性生殖器以及隐藏的第7和第8腹节腹板。纠正了Centris pulchra原始描述中报告的副模式标签的排版错误。在此将Centris pulchra的一只雌性副模式指定为Centris byrsonimae sp. n. 的副模式。提供了巴西东北部Centris狭义物种的更新清单，包括地理分布参考以及pulchra物种组的鉴定检索表。
