The taxon Ephydra basilaris has been described by Waltl (1837) from
Passau (Bavaria). The description is copied by Meigen (Meigen, 1838),
but without reference to Waltl´s work, and thus pretending to be
a new description. The taxon basilaris is
here regarded as a synonym of the nominal Notiphila femorata on the
following grounds:
The description of Waltl states: "Gesicht grauweiß, mit
weißem Augenrande. Stirn rostbraun, mit dunkeln Striemen.
Rückenschild braungrau, mit drey braunen Striemen. Hinterleib sehr
glänzend: 1. 2. Ring rostgelb, die andern schwarz. Beine
braungelb. Flügel getrübt, mit braunen Queradern"
(translation: Face gray-white, with white margin around the eye.
Forehead rubiginous, with dark striae. Thoracic shield brown-gray, with
three brown striae. Abdomen very shiny: 1. and 2. segment rubiginous,
the others black. Legs brown-yellow. Wings clouded, with brown
crossveins). This description fits very well with Philygria femorata.
It is the only fully winged Philygria species in Europe that has only
the
abdominal tergites 1 and 2 pruinose and the remaining segments are
shiny black. All other details of Waltl´s description fit as
well. The basilaris taxon is regarded a nomen dubium by Mathis and
Zatwarnicki (1995). I believe that the above arguments allow a
tentative synonymization with Philygria femorata.
Note:
Hydrina strandi is a doubtful species and listed as nomen dubium by
Mathis and
Zatwarnicki (1995). The types have been destroyed in World War II
(Hollmann-Schirrmacher, 1998) and thus no comparisons can be made.
Probably a synonym of another Philygria species: Hollmann-Schirrmacher
suggests that the description of Hydrina strandi suggests synonymy with
Philygria femorata. I agree with this notion and list it here as a
synonym of this species. Only
known from the type locality (St. Wendel (near Saarbrücken),
Germany).
