Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 65-66

geniculata Macquart, 1835 , Anthomyia

Anthomyia geniculata Macquart, 1835: 339 (junior primary homonym of Anthomyia geniculata Bouché,

1834). Syntypes ♂ and ♀, “du nord de la France ” ( France, Lille area), not in MNHN or MHNL, and presumed destroyed.

MATERIAL. — Described from an unspecified number of specimens of both sexes. No syntypes have been located.

CURRENT IDENTITY. — The name was listed by Bezzi & Stein (1907: 717) and Hennig (1976: 922) as an unrecognized species of the Anthomyiidae . However, Macquart himself states that the species is “semblable à la nitida ” (i.e. Anthomyia nitida Macquart, 1835 ), which is a junior synonym of Fannia serena (Fallén, 1825) (see below under Anthomyia nitida Macquart, 1835 ). Anthomyia geniculata differs from A. nitida by the slightly larger size, “reflets blancs” on the body, and yellow knees. In these respects, it agrees with Fannia sociella (Zetterstedt, 1845) , and I have synonymized Macquart’s name with Fannia sociella ( Pont 1986a: 56) .
