Pont, Adrian C., 2012, Muscoidea (Fanniidae, Anthomyiidae, Muscidae) described by P. J. M. Macquart (Insecta, Diptera), Zoosystema 34 (1), pp. 39-111 : 69-70

limbinervis Macquart, 1849 , Hydrophoria

Hydrophoria limbinervis Macquart, 1849: 490 , pl. 6, figs 7, 7a-7c. Lectotype ♀, “environs d’Alger ” ( Algeria, Algiers area), by present designation, in MNHN.

MATERIAL. — Macquart described this species from the ♂ sex only, and the collector Lucas added the following information on distribution: “Cette espèce habite les environs d’Alger; je l’ai prise en mars, à Kouba, dans les lieux humides; je l’ai rencontrée aussi aux environs du cercle de Lacalle.” In fact, Macquart’s fig. 7 shows a ♀, not a ♂, and the only surviving syntype is also a ♀, under no. 233 of the Macquart collection in MNHN. The labels include a green disc with “220 bis” on the reverse, and a printed label “Muséum Paris / Algérie / Coll. H. Lucas 78-49”. There is no Macquart label. I have labelled it and designate it herewith as lectotype. It is in rather poor condition: it is quite mouldy, with both forelegs and tarsomeres 2-5 of right hind leg missing .

There is an Algerian ♂ in the Bigot collection in OUMNH, but it is labelled “ Constantine ” by Bigot and it is not a syntype.

CURRENT IDENTITY. — Bezzi & Stein (1907: 641) included this as an unrecognized species of Mydaea Robineau-Desvoidy, 1830 , but it has been synonymized with Phaonia trimaculata (Bouché, 1834) by Séguy (1937: 338), Hennig (1963c: 885) and Pont (1986b: 132). Pending further work on the various Mediterranean forms currently named as “ Phaonia trimaculata ”, this identification is correct. The OUMNH ♂ is also Phaonia trimaculata .
