Centris (Melacentris) obsoleta Lepeletier de Saint Fargeau, 1841

Centris obsoleta Lepeletier de Saint Fargeau, 1841: 153

Centris obsoleta pleuralis Friese, 1901: 272 [New lectotype designation]. New junior subjective synonymy.

Centris obsoleta pleuralis lectotype (♀, Figs 17–20): Friese based the description on a manuscript name provided by Mocsáry (“Mocs. i. l.” or Mocsáry in litteris) from an unknown number of specimens in HNHM. The single female labeled “Piauchy / Brasilia [printed]”, “848 / 87”, “28.” [green label], “ C. obsoleta ♀ / v. pleuralis / det. Friese 1898 / Mocs.” is here designated as the lectotype. The type locality is Piauí, Brazil, and according to the accession book at HNHM the specimen was purchased from E. Menkl in 1889. Moure et al. (2007) considered C. obsoleta and C. pleuralis as two valid and distinct species. However, our examination of both primary types indicates the opposite and they are here considered synonymies. A syntype of C. obsoleta is in OUMNH.
