REMARKS: Rondani (1861e: 39) described both sexes of Frontina instabilis without specifying the exact number of specimens and not giving a range of lengths, from material he had collected and also received from D’Arco. We found 20 syntypes in this study. Rondani placed this nominal species in the subgenus Prosopea Rondani, 1861 , which is now considered as a valid genus ( O’Hara et al. 2011: 151).
