floccosa Macquart, 1835 , Hydrotaea

Hydrotaea floccosa Macquart, 1835: 307 . Lectotype ♂, “du nord de la France ” ( France, Lille area ), by present designation, in MNHN.

MATERIAL. — No syntypes were found in the Macquart collection in MHNL, but a ♂ was found amongst the miscellaneous Macquart material in MNHN. It is labelled “300 bis” and “ Hydrotaea / floccosa” by Macquart, and it is evidently a syntype. I have labelled it and designate it herewith as lectotype. It is very damp and covered with dirt and mould, but it is quite recognizable specifically. CURRENT IDENTITY. — The name floccosa has always been treated as a junior synonym of Hydrotaea armipes (Fallén, 1825) ( Bezzi & Stein 1907: 650; Hennig 1962c: 710), and the lectotype does indeed belong to the species to which the name H. armipes was formerly applied. However, the lectotype of H. armipes was found to belong to the species previously known as H. occulta (Meigen, 1826) ( Pont 1984: 281) , and so the name Hydrotaea floccosa must be used for H.armipes of authors (see Pont 1986b: 78).
