Centris flavifrons brasiliana (Christ, 1791) Apis flavifrons brasiliana Christ, 1791: 140 (junior synonym of C. flavifrons). Type data This variety was proposed based on an undetermined number of females collected in Brazil.Unfortunately, the whereabouts of the type material are currently unknown. Type locality Brazil. Karl Wilhelm von Dalla Torre Karl Wilhelm von Dalla Torre (1850–1928) was an Austrian naturalist. He studied mathematics and natural sciences at the Universität Innsbruck, where he was later hired as professor of zoology (Clément 1928). He studied actively the taxonomy of Hymenoptera, where he published several classic works on specific groups as well as the first catalogues of the order. Dalla Torre died in Innsbruck, aged 77. Dalla Torre’s Centris bee Dalla Torre did not describe any species of Centris, but instead proposed a new name for C. thoracica Smith, 1874, a junior homonym of a species previously described by Lepeletier (1841). The primary type of C. thoracica Smith is currently housed at NHMUK and it bears the following data label: [redrimmed circular label] Type H. T. [printed]\ B.M. TYPE HYM. [printed] 17B.904. [handwritten]\ St. Dom. 55.1. [printed]\ Centristhoracica Smith (Type) [handwritten]\ NHMUK 01081396 [QR code] (NHMUK).
