Meigen, 1822 (p. 11)
Note: this is a doubtful species and has been
described by Meigen (1822) already as
"Unbestimmte Abtheilung" (= incertae sedis).
It is based on a single specimen that has been
available to Meigen from the collection of his
cousin Johann Matthias Baumhauer. Baumhauer
was a merchant in Aachen and was a passionate
collector of butterflies, but later also
collected several other insects. Baumhauer was
no scientist and his collection therefore
often lacked information about the specimens.
This is also the case here: the origin of the
single female specimen is unknown. However,
there is reason to believe that most fly
specimens in Baumhauer´s collection were
from the Aachen area: Baumhauer startet his
collection with butterflies and it is likely
that he mainly collected spectacular tropical
specimens, because at the time amateur
butterfly collections were mostly for the sake
of aesthetics. It was only after Meigen had
introduced Baumhauer to insect systematics and
taxonomy that Baumhauer also became interested
in the scientific revision of his huge
collection. This revision was mainly done by
Meigen himself. At the same time this might
have been the incentive for Baumhauer to study
other insects as well. If so, then it is
likely that he started collecting these from
the surroundings where he lived (=Aachen,
Germany), instead of spending money on buying
"unspectacular" insects like flies. Thus, it
is at least possible that the single known
specimen of Hilara fasciata was collected in
Germany. In any case the specimen can be at
least considered European in origin, because
the title of Meigen´s book suggests this
(transl. "Systematic description of the known
European dipteran insects"). This specimen (if
still extant) urgently requires revision,
because it is likely identical to some other
Hilara or Empididae species.
