Centris modesta Smith, 1854 . 371, 372. Type data: Smith (1854) described this species based on an undetermined number of male specimens collected in an unknown locality in Brazil . A specimen belonging to the type series is currently housed at NHMUK and is here designated the lectotype . The specimen has the following data label: Type H. T . [red-rimmed circular label, printed]\ B.M. TYPE HYM . [printed] 17B.908 [handwritten]\ [light blue label] Brazil [handwritten]\ Centris modesta Sm Type [handwritten]. Type locality: Brazil . Comments: Shortly after its description, C . modesta was proposed as a junior synonym of C . obsoleta ( Ducke, 1910 ) . This synonymy remained unchanged until now that the lectotypes of both species were studied in detail. Although superficially similar, both species are valid, so the synonymy proposed by Ducke (1910) must be no longer considered correct. The type locality cannot be further narrowed down than to Brazil , although Friese (1901) mentioned that the specimen was collected in the northern locality of Santarém.
