Lasia cuprea Rondani, 1863 ORIGINAL DESCRIPTION: 1863: 75. TYPE LOCALITY: “ Chiliae [Chile]”. TYPE MATERIAL: 1 ♀, syntype (MZUN: Box with no identification label): Lasia cuprea Rond., Chili [= Chile] / M. Zool. N° 11082. CURRENT STATUS: valid species, senior synonym of Panops nigripes Philippi, 1865 (new synonymy, this work). See Remarks. REMARKS: Rondani (1863: 75) described Lasia cuprea, without specifying either the number or the sex of the specimens, but giving a single measurement of length, from material received from R.A. Philippi under the name “ ocelligera ” and characterized by black legs (“ Pedes nigricantes ”). Philippi (1865: 648) described Panops nigripes from a single specimen collected in Chile, similar to Panops ocelliger Wiedemann, 1830, but with black femora. Edwards (1930: 195) and Stuardo (1946: 102) incorrectly considered Lasia cuprea Rondani, 1863 as a possible synonym of Lasia nigripes Philippi, 1865 (applying the Principle of Priority Lasia nigripes should be the junior synonym of Lasia cuprea). González et al. (2018: 433) considered Lasia cuprea and Lasia nigripes as valid species. No specimen under the name Panops nigripes is present in the MNHNS (M.E. Elgueta Donoso, pers. comm., 2018) where Philippi’s collection is preserved. We found one syntype of Lasia cuprea in the MZUN. In our opinion Rondani and Philippi described two different nominal species based on the same specimen, thus Panops nigripes Philippi, 1865 must be considered as a junior synonym of Lasia cuprea Rondani, 1863, new synonymy.
