Genitalia of
Atheta pennsylvanica
Bernhauer
(male, 8 km S New Windsor, New York (114–115); female, holotype of
At. fontis
Casey
(112); and female, 8 km SEE Springfield, Vermont (113)). 112–113 — spermatheca; 114 — median lobe, parameral view; 115 — median lobe, lateral view. Scale bar 0.1 mm.
Diagnosis.
Atheta pennsylvanica
belongs to a group of distinctly colored species within
Microdota
with dark brown head and abdominal terga 5–8, light brown elytra, and reddish yellow pronotum and abdominal terga 3–4.
Atheta pennsylvanica
can be distinguished from other species of this group by having a larger body size and the distinct shape of the aedeagus (
Figs. 114–115
) and spermatheca (
Figs. 112–113
).
Discussion.
The
types
of
At. fontis
are similar to the
types
of
At. pennsylvanica
in the body size, in external characters and in the shape of the spermatheca. Therefore, the synonymy of the two species established by
Fenyes (1920)
and
Bernhauer & Scheerpeltz (1926)
is confirmed. I agree with
Bernhauer & Scheerpeltz (1926)
that of all species of
Microdota
described by
Casey (1910a
,
1911a
) only
At. fontis
is synonymous with
At. pennsylvanica
.
Distribution.
Atheta pennsylvanica
is widespread in the eastern
United States
(
Vermont
,
Massachusetts
,
New York
,
Pennsylvania
and
Minnesota
) and is also known from eastern
Canada
(
Ontario
,
Québec
).
