REMARKS: Rondani (1866a: 168) described Chorthophila incognita from two males: “ Exemplaria duo mascula inveni in collect. Mussino [I found two males in Mussino’s collection]”. We found just one male in the MZUF, which Hennig (1970a: 374) considered as the “Typen” [= type] and therefore implicitly designated it as the lectotype, even though he incorrectly labeled it “ holotypus ” (I.C.Z.N. 1999: Article 74.5). Rondani described this nominal species under the generic name Chorthophila , which is an “unjustified emendation of Chortophila Macquart, 1835 ” ( O’Hara et al. 2011: 57).
