Distribution.
U.S.A.
(
Summers 1962
) and
Turkey
(this paper).
Remarks.
This species was known only from the
U.S.A.
(
Summers 1962
). This is the second record of the species. The Turkish specimens resemble
Stigmaeus glabrisetus
in general appearance, but apodemal marking is not evident and the ratio
d
/
l'
is 2.6 in
U.S.
A specimens, but 2.1 in the Turkish specimens.
