Diagnosis
Scatophila iowana
Wheeler has entirely black legs, a yellow haltere, a matt brown mesonotum and a brownish microtomentose abdomen. It lacks the pair of pronounced facial setae typical for
S. despecta
(Haliday). The wing and mesonotal patterns of
Scatophila iowana
resemble those of
S. caviceps
(Stenhammar). Males of these two species can be identified by the shape of the central part of the face: somewhat protruding between well-defined antennal grooves in
S. iowana
, weakly concave and without antennal grooves in
S. caviceps
.
The anepisternum of
S. iowana
is rather uniformly brownish;
S. caviceps
has a grey anepisternum with two brown spots, one around the base of the anepisternal bristle and one at the ventral margin.
The male terminalia of
S. iowana
are characterized by the anterior margin of the epandrium, which is slightly concave, and the aedeagus, which consists of three sclerites. In
S. caviceps
the anterior margin of the epandrium bears a medial projection and the aedeagus is a one-piece structure.
Distribution
First recorded from Finland by
Zatwarnicki and
Kahanpaeae
(2014)
.
Scatophila iowana
is a Holarctic species. It is probably widespread in Europe, but its distribution remains poorly known (
Zatwarnicki 2013
).
