I studied the primary types of Centris bees described by the naturalist, botanist and entomologist Adolf Ducke. The type specimens of C. caxiensis, C. friesei, C. hyptidis, C. maranhensis, C. ocellaris, C. singularis, and C. superba were analysed, providing information on their current status and depository of primary and secondary type specimens. To stabilise the application of some names, lectotypes for C. friesei and C. singularis were also designated. In addition, morphological characters useful in recognition of the species studied are also provided.
