CURRENT STATUS: junior synonym of Pegomya terminalis (Rondani, 1866) ( Dely-Draskovits 1993: 87, Gorodkov et al. 1995: 8).

REMARKS: Rondani (1866a: 170) described both sexes of Chorthophila divergens , from an unspecified number of specimens: “ Uterque sexus… a me lectus fuit [Both sexes were collected by me]”. Hennig (1973b: 650) reported one male and one female (pinned together) in the MZUF. In his redescription of the species, Hennig did not unambiguously designate a lectotype, but defined the male as “ Lectotypus ” and then, in the caption of figure 585 representing the male terminalia, indicated this same male as “ Holotypus ”. This latter specimen must therefore be considered as the lectotype (I.C.Z.N. 1999: Article 74.5) and the female as paralectotype. 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).
