Musca basilaris, Macquart, 1835

Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 51

basilaris Macquart, 1835 , Pegomyia

Pegomyia basilaris Macquart, 1835: 353 . Syntype (s) ♀ (♀), “je l’ai reçue de Bordeaux” ( France, Bordeaux), not in MNHN or MNHL, and presumed destroyed.

MATERIAL. — Described from an unspecified number of ♀♀. No syntypes have been located.

In the Macquart collection in MHNL, in the penultimate (unnumbered) box, there is a single specimen labelled by Macquart “ A. basilaris / Mai. Lest.” (Lest. = Lestrem, Macquart’s home town in northern France). This is not a syntype. It is very mouldy and quite unrecognizable though its size and general habitus are those of a species of Helina Robineau-Desvoidy, 1830 , such as H. impuncta (Fallén, 1824) .

CURRENT IDENTITY. — The name was listed by Hennig (1974a:681) and Dely-Draskovits(1993:89) as an unrecognizedspeciesofthegenus Pegomya Robineau-Desvoidy, 1830 . Macquart’s brief description fits the common European Pegomya solennis (Meigen, 1826) , a synonymy suggested to me by Dr V. Michelsen (pers. comm.), who has studied Meigen’s type. The name Pegomyia basilaris is herewith synonymized with Pegomya solennis (Meigen, 1826) (n. syn.).
