Discussion.
Wirth’s (1953a)
original description of this species was based on the male
holotype
from Collier Co. and a female from Citrus Co. about which he stated “…is provisionally referred to
S
.
(
S
.)
thomsenae
, since it resembles the male in coloration, although it may prove to be a dark specimen of
S
.
(
S
.)
bulla
.” Under “diagnostic characters” for
S. thomsenae
,
Wirth (1953a)
noted “Very closely related to, and almost indistinguishable from
bulla
Thomsen
, except for the very characteristic male genitalia.”
During ensuing years, Wirth identified and labeled approximately 30 slide-mounted females in the FSCA as
S. thomsenae
as well as a many more specimens as
S. bulla
. Our examination of these slidemounted specimens of
S. bulla
and
S. thomsenae
in the FSCA revealed that the wing of both sexes of
S. bulla
have a narrow fringe of macrotrichia on the anterior wing margin past the terminus of the costaradius and continues beyond the wing tip to at least the terminus of vein M
1
and sometimes beyond M
2
, especially in females. Among the FSCA material were
three females
and
two males
of
S. thomsenae
from
Jamaica
that lack macrotrichia on their anterior wing margins. Based on this fact, we determined that most of the FSCA material identified by Wirth as
S. thomsenae
are actually specimens of
S. bulla
, and therefore, WLG relabeled these “
Stilobezzia bulla
Thomsen, Det. Wm. L. Grogan, Jr.
”
Wilkening et al. (1985)
listed
S. thomsenae
from Alachua, Calhoun, Citrus, Collier (
holotype
), Dade, Gilchrist, Glades, Gulf, Indian River, Jefferson, Liberty, Orange and Wakulla counties. However, in addition to the
holotype
male from Collier Co. (USNM), we can only confirm other specimens of
S. thomsenae
in the FSCA from Alachua, Dade, Glades and Indian River counties. We also provide the first records from Levy, Putnam, Sarasota and St. Lucie counties.
