nitida Macquart, 1835 , Anthomyia

Anthomyia nitida Macquart, 1835: 338 . Lectotype ♂, “commune au 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 is now no material in MHNL, but Hennig (1976: 924) found 1 ♂ and 1 ♀ in MNHN labelled as Anthomyia nitida by Macquart. He identified the ♂ as belonging to the genus Fannia Robineau-Desvoidy, 1830 , and thought that the ♀ might be a syntype of Anthomyia frontalis Macquart, 1835 (see above). Only the ♂ can be a syntype of A. nitida . It is labelled by Macquart “N°. 330. X / Anthomyia / nitida.”. I have labelled it and designate it herewith as lectotype. It is not in good condition: it has been largely eaten by beetle larvae, and only vestiges of the head and thorax remain on the pin; right wing missing; all legs missing except left mid leg and right hind leg. I have removed the abdomen, macerated it, and placed it in a vial of glycerine attached to the specimen. The ♀ is labelled by Macquart “330” and “ Anthomyia / nitida.”.

CURRENT IDENTITY. — Bezzi & Stein (1907: 721) listed A.nitida as an unrecognized species of Chortophila Macquart, 1835 . Séguy (1937: 105) caused some confusion by listing Anthomyia nitida Macquart (1835: 338) and Hylemyia nitida Macquart (1835: 321) under one entry in the genus Hylemyia Robineau-Desvoidy, 1830 . Hennig (1976: 924) referred to Anthomyia nitida but gave it the page reference (p. 321) of Hylemyia nitida . The lectotype is in fact a ♂ of Fannia serena (Fallén, 1825) , and this synonymy was published by Pont (1986b: 55). Enough remains of the lectotype to see the linear lower calypter, two prealar setulae, uniserial post-ocular setulae, and the identification is confirmed by the terminalia. The ♀ is also Fannia serena . Unfortunately, this synonymy creates a secondary homonymy in the genus Fannia Robineau-Desvoidy, 1830 . Homalomyia (now Fannia ) nitida Stein, 1895 , now becomes a junior secondary homonym of A. nitida , and the replacement name Fannia pauli Pont, 1997 , has been proposed for Fannia nitida ( Rozkošný et al. 1997: 44) .
