Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 63-64

frontalis Macquart, 1835 , Chortophila

Chortophila frontalis Macquart, 1835: 325 . Lectotype ♀, “du nord de la France ” ( France, Lille area ), by present designation, in MNHN.

MATERIAL. — Described from an unspecified number of ♀♀. Macquart (1850c: 535) recorded this species as present in the MHNL collection. There are now no syntypes in the Macquart collection in MHNL, but Hennig (1974a: 753) found 1 ♀, evidently a syntype, in the miscellaneous Macquart material in MNHN. There are two labels in Macquart’s hand, “324” and his determination “ Chortophila / frontalis”. This ♀ is slightly dirty and has all left foretarsomeres, right foretarsomeres 3-5, and right mid tarsomeres 4-5 missing; otherwise it is well preserved. I have labelled it and designate it herewith as lectotype.

CURRENT IDENTITY. — The name frontalis was synonymized with Delia radicum (Linnaeus, 1758) by

Hennig (1974a: 752, as brassicae (Wiedemann, 1817)) and Dely-Draskovits (1993: 49). Hennig (op.cit.: 753) also pointed out that Macquart’s ♀ of frontalis could be either Delia radicum or Delia floralis (Fallén, 1824) , which are hardly distinguishable in the ♀ sex. If the differences given by Ringdahl (1959: 298) hold good, then this ♀ is indeed D. radicum . From the point of view of formal nomenclature, however, the actual identity makes no difference as C.frontalis is junior to the other two names, and Hennig’s decision to synonymize Chortophila frontalis with Delia radicum should be followed.
