Comments: Rondani (1863, 1864) cited the name Lasia aenea attributed to Philippi in a handwritten label, from Chile, as synonym of L. rufipes Westwood, 1848 from Brazil and is highly improbable the presence of this species in Chile. This erroneous indication was followed by Costa (1866: 38), Schiner (1868: 143) and Hunter (1901: 152). On the other hand, Lasia aenea Rondani, 1863 is a nomen nudum. corvina Erichson, 1840: 143.

Syntypes: Chile (MZUN). Dist.: Chile.

Comments: Lasia cuprea Rondani has been cited as possible—not definitive—synonym of L. nigripes (Philippi) by some authors (Edwards, 1930; Stuardo, 1946). Rondani (1863, 1864), in his description, stated that Philippi identified or named it as L. ocelligera. On the other hand, Philippi (1865) distinguished Lasia ocelliger (as Panops, a misidentification as this name is proper of a Brazilian species) from his Lasia nigritarsis (as Panops). This leads to consider both as valid species, until a posterior study clarify its taxonomic status. metallica Rondani, 1863: 75. Syntypes: Chile (MZUN).
