Diagnosis. Specimens of A. affabra are glabrous and lack the conspicuous setation of the other two species. Other morphological details with diagnostic value are the prominent subapical callosity on the elytron and the ventrodistally unmodified fifth tarsomere.

Notes. Centrinus affaber was indexed without page number in Hustache (1938) but did not appear in the catalogue itself. Because of the confusion with B. affaber , the name has never been transferred formally to Anthobaris . The type specimen for C. affaber , an almost black, probably greasy female from the State of Minas Gerais ( Fig. 1 ), agrees morphologically with bluish specimens from the southerly adjacent state. Hustache probably had seen the type in preparation of the Junk Catalogue but did not associate the name with the bluish specimens described as A. denticulata . My well-preserved specimen from Cipó ( Fig. 3 ) shows the natural metallic luster of this species. I have seen only females. Baridius affaber is removed here from Anthobaris and transferred to Baridinae incertae sedis.
