Current status: Oplomus pulcher Dallas, 1851 .

Note: From Walker (1867a: 120), we know that Dallas had, at least, two specimens from Mexico, from Mr Argent (this is corroborated by the fact that Dallas gave a range of measurements: “Long. lin. 6½–7½”). We have found them both. Thomas (1992: 62) explained: “The type of Oplomus pulcher is a female and was located in the British Museum (Natural History). It is labeled: (a) “Type,” (b) “a,” (c) “ Oplomus pulcher ” The specimen is metallic blue with humeral angles and tip of the scutellum red.” By giving its labels data, describing it and calling the specimen “the type”, Thomas has “unambiguously selected [this] particular syntype to act as the unique name-bearing type of the taxon” (ICZN 1999, Art. 74.5).
