Diagnosis.
See
Pace (1989)
.
Discussion.
Pace (1989)
designated the
lectotype
of
Le.
brevicollis
, however from the original description (
Casey 1893
) it is clear that Casey had a single male type of this species. This type is the
holotype
of
Le.
brevicollis
and Pace's
lectotype
designation is redundant.
Pace (1989)
did not have an opportunity to examine the types of
Le.
laticollis
. Unfortunately, the
holotype
of
Le.
laticollis
, like some other Notman’s staphylinid types deposited at SIIS, is almost completely destroyed. The female
paratype
and two additional male specimens from
New York
, identified by Notman as
Le.
laticollis
, are similar to the
holotype
of
Le.
brevicollis
in external characters and in the shape of the aedeagus.
Distribution.
Leptusa brevicollis
is known from
Pennsylvania
,
New York
and
New Hampshire
.
