As noted by
Zetterstedt (1852, 4225)
the male and female of the couples were taken in copula, and thus the females should be safely associated with the male.
Edwards (1924)
misinterpreted this species as
Allodia griseicollis
(Meig.) sensu
Lundström (1909)
nec
Staeger (1840)
, and suggested to use Zetterstedt's name for it. While the intention presumably was to avoid mixing with B.
griseicolle
(Staeger, 1940)
this rather led to a mixing of
B. griseolum
with
B. canescens
where the first name has later been widely used for the latter species. Further, this species is a senior synonym of
Brevicornu boreale
(Lundström, 1914)
[
type
specimen has been studied, compared with the
lectotype
of
B. griseolum
and found to be conspecific].
