FEMALE-Length 5.5 mm.; head and
thorax black, abdomen ferruginous; head very
much broader than long; eyes subparallel;
clypeus extremely short and broad, its breadth
about 4 times the length, rather flat, only
slightly convex medially; labrum nearly as
long as broad, rather narrowly rounded apically,
dull ferruginous, becoming piceous at base;
mandibles slender and somewhat elongate, with
a very minute and obscure, inner, subapical
tooth, brownish-testaceous medially, becoming
dark at base and reddened apically; antennae
black at base, becoming brownish-red apically,
segments 1, 2 and 3 of flagellum broader than
long, the following segments about as long as
broad; lateral ocelli considerably nearer to
each other than to eyes; face below ocelli
shining, very minutely punctate, punctures
distinctly but not widely separated, becoming
slightly coarser below where they are
partially obscured by tomentum; supraclypeal
area very broad, punctures very fine and well
separated, those on clypeus minute and rather
close across upper margin, becoming somewhat
deeper and more distinct, but rather
sparse and irregular, apically; vertex between
eyes and ocelli shining, punctures exceedingly
minute and quite sparse, hind margin only
very obscurely roughened, cheeks somewhat
shining, with exceedingly minute and
obscure but rather close punctures above,
becoming smooth and shining below; wings
subhyaline, with the usual three submarginal
cells, veins pale testaceous, stigma more
brownish-piceous; tegulae testaceous-hyaline;
legs brownish-piceous basally, becoming more
brownish-testaceous apically; scutum and scutellum
shining, punctures exceedingly minute
and quite indistinct, well separated on scutum
except at extreme sides and narrowly
across anterior margin, those on scutellum
quite sparse, minute and obscure; pleura dull,
finely rugose, hypoepimeral area shining, with
a few, minute and obscure punctures; dorsal
area of propodeum with a basal fringe of
very short striae, apical portion smooth and
shining, lateral faces dull, subrugoso-striate,
posterior face with a few obscure and shallow
reticulations; abdominal terga smooth and
shining, basal tergum impunctate, 2nd with
minute but rather distinct and close punctures
across basal half, apical half practically impunctate,
terga 3 and 4 more fully and uniformly,
finely and closely punctate, apical margins
of all rather broadly depressed and impunctate,
distinctly yellowish-hyaline.
MALE-Length 5 mm.; head and thorax
black, abdomen ferruginous basally, becoming
black apically; head very slightly broader
than long; eyes very slightly convergent below;
clypeus short and very broad, with a very
slight median impression, only slightly convex;
mandibles testaceous, becoming somewhat darker
basally; antennae black basally, flagellum
becoming somewhat more brownish-piceous
apically, segments 1 and 2 slightly broader
than long, following segments with length and
breadth subequal; lateral ocelli slightly nearer
each other than to eyes; face rather thinly,
white pubescent, exposing the surface even below,
somewhat shining, punctures minute and
slightly separated between eyes and antennae,
those on supraclypeal area slightly deeper and
more distinct, well separated, those on clypeus
equally fine and similarly spaced along basal
margin, becoming slightly more coarse and
close apically; face above antennae shining,
punctures minute and indistinct, slightly
separated, becoming even more minute on vertex
between eyes and ocelli, hind margin becoming
somewhat roughened and dull; cheeks
above rather smooth but only very obscurely
punctate, lower surface becoming smooth and
shining; wings subhyaline, with the usual
three submarginal cells, veins pale testaceous,
the more basal veins and stigma more brownish-
piceous; tegulae brownish-testaceous; legs
piceous in large part, the more apical tarsal
segments becoming brownish-testaceous; scutum
and scutellum shining, punctures minute
and indistinct, well separated over most of
scutum, becoming somewhat more close and
distinct laterally and anteriorly, those on scutellum
very minute and obscure; pkura dull,
relatively smooth, being only subrugose anteriorly
and above, but the hypoepimeral area
smooth and shining, with a few, very shallow
and obscure punctures; dorsal area of propodeum
very narrowly, finely and irregularly
striate along basal margin, the apical portion
rounded, smooth and shining, lateral faces
dull, subrugose, and posterior face subrugose;
abdominal terga smooth and shining, basal
tergum practically impunctate, 2nd with wry
fine and rather close punctures across base,
these becoming very sparse apically, 3rd somewhat
more fully punctate, the apical margin
of all rather broadly impressed, impunctate,
conspicuously yellowish-hyaline; gonostyli
barely reaching tips of penis valves, very slend
er, with an apical, slender, finger-like projection
which bears a few very fine setae. (resembling
autumnalis, fig. 117, but smaller and
more slender).
DISTRIBUTION - North Carolina to
Florida ; April and May.
FLOWER RECORD-Asclepias.
Collection records suggest a possible
parasite-host relationship of this species
with Calliopsis andreniformis.
