Genitalia of
Boreophilia angusticornis
(Bernhauer)
(male, lectotype of
Atheta angusticornis
(120–123); and female, lectotype of
Metaxya plutonica
Casey
(124)). 120 — median lobe, parameral view; 121 — apex of median lobe with retracted internal sac, abparameral view; 122 — median lobe, lateral view; 123 — apex of median lobe with retracted internal sac, lateral view; 124 — spermatheca. Scale bar 0.2 mm.
Lectotype
of
Metaxya plutonica
(here designated):
♀
, “
Subalpine
Mt.
Wn. [

Csy.
”, “TYPE USNM 39064” (red label), “CASEY bequest 1925” (
NMNH
).
Diagnosis.
Boreophilia angusticornis
is closely related to Palaearctic
Boreophilia subplana
(J.
Sahlberg, 1880
)
but differs in the shape of the aedeagus (
Figs. 120–123
), particularly a narrower apex of the median lobe (in parameral view) (cf.
Fig.
73
in Brundin 1953 and
Fig.
120
in this paper).
Discussion.
The
lectotype
of
Me.
plutonica
and the
paralectotype
of
At. angusticornis
are similar in external characters and also in the shape of the spermatheca. The two species were described from the same locality. I consider
Me.
plutonica
to be a synonym of
Boreophilia angusticornis
.
Distribution.
Boreophilia angusticornis
is known only from the Mount
Washington
,
New Hampshire
. This area was affected by the last glaciation and is unlikely to have relict endemic species.
Boreophilia angusticornis
may occur in other high mountains of the northeastern
United States
and also in
Canada
, at lower altitudes further north.
