Taxonomy of Protopolybia exigua species-group

The group of species referred here as the Protopolybia exigua species-group comprises 13 species. Four new species are described and one revalidated, and several new occurrences are recorded. Descriptions of new species and redescriptions of P. exigua , P. holoxantha , and P. rubrithorax Bequaert are presented below, as well as an identification key for the P. exigua species-group. Measurements of the female clypeus are presented in a relative scale given in “units of the minimum clypeus width” (MiWClp). The data about species distribution, not originating from the material examined, were taken from Richards (1978), Sarmiento (1994) and Silveira & Carpenter (1995).
