Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 77

nitida Macquart, 1835 , Hydrophoria

Hydrophoria nitida Macquart, 1835: 301 . Lectotype ♂, locality not given but “je l’ai trouvée dans les prairies aquatiques, au mois de juin” ( France, Lille area ), by present designation, in MHNL.

MATERIAL. — Macquart did not give any locality for this species. Macquart (1850c: 533) recorded this species as present in the MHNL collection. There is 1 ♂ in box F of the Macquart collection in MHNL, which I consider to be a syntype. It is in good condition, with right mid leg missing and right wing broken. The drawer label reads “H. / nitida / Meig. [sic] Lille”. I have labelled it and designate it herewith as lectotype.

In MNHN, there are 2 ♂♂ syntypes. One is labelled by Macquart “N°. 299. X / Hydrophoria / nitida.” ; the other is labelled “299” and “nitida”. I have labelled them both as paralectotypes.

CURRENT IDENTITY. — Hydrophoria nitida has consistently been treated as a good species of Phaonia Robineau- Desvoidy, 1830 (e.g., Hennig 1963b: 848), and this is correct according to the lectotype. The species is now called by the older name of Phaonia nymphaearum (Robineau-Desvoidy, 1830) ( Pont 1986b: 126) . The two paralectotypes are conspecific with the ♂.
