Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 60

dubia Macquart, 1835 , Caenosia

Caenosia dubia Macquart, 1835: 346 . Syntype (s) ♀ (♀), “du nord de la France ” ( France, Lille area), not in MNHN or MHNL, and presumed destroyed.

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

CURRENT IDENTITY. — This species was included as an unrecognized species of Coenosia Meigen, 1826 , by Bezzi & Stein (1907: 738) and Hennig (1962a: 618). The description is the same in all respects to that of the preceding species Coenosia monilis Meigen, 1826 , and it seems to me that Macquart did not in fact recognize Meigen’s species in his own material, that he gave a selection of characters from Meigen’s description (translated verbatim into French) as his own description, and that he then redescribed the species as dubia . The synonymy of Macquart’s name with Anthomyia monilis (Meigen, 1826) was established by Pont (1986b: 215) and was accepted by Dely-Draskovits (1993: 21).

Caenosia dubia Macquart, 1835 , is the type-species of the genus Eriostyla Lioy, 1864 ( Lioy 1864: 997) , which thus becomes a junior synonym of Anthomyia Meigen, 1803 , and an objective junior synonym of Chelisia Rondani, 1856 (see Pont 1986b: 215).
