floccosa Macquart, 1835 View in CoL , Chortophila

Chortophila floccosa Macquart, 1835: 326 . Lectotype ♂, “du nord de la France ” ( France, Lille area ), by present designation, in MNHN.

MATERIAL. — Described without statement of sex or number of specimens. No material was found in the Macquart collection in MHNL, but 1 ♂ was found in the miscellaneous Macquart material of MNHN. It is labelled by Macquart “320” and “ Chortophila / floccosa” and is evidently a syntype. I labelled it as lectotype, and the lectotype designation has been effectuated by Griffiths (1991: 970). Apart from a little dust and mould, it is in excellent condition.

CURRENT IDENTITY. — Bezzi & Stein (1907: 712), Hennig (1974a: 752) and Dely-Draskovits (1993: 49) have treated this name as a junior synonym of the cabbage root fly Delia brassicae (Wiedemann, 1817) (now correctly called Delia radicum (Linnaeus, 1758)) , and this synonymy is correct. The lectotype shows well the “cuisses postérieures à poils assez courts, touffus près de la base” which Macquart mentioned in his description and which is a diagnostic character for ♂♂ of D. radicum .
