FEMALE-Length 4 mm.; head and thorax
black, abdominal segments 1 and 2 entirely
ferruginous, 3rd becoming darkened apically,
following segments piceous; head nearly as
long as broad; eyes only very slightly convergent
below; clypeus very slightly convex;
labrum about as long as broad, quite evenly
rounded, yellowish-testaceous except for the
somewhat darker base; mandibles quite slender,
with a barely discernible, inner, subapical
tooth, color testaceous, becoming ferruginous
apically; antennae black basally, becoming
brownish apically, basal segment of flagellum
broader than long, about equal in length to
pedicel, 2nd segment not much longer, 3rd
and following segments very slightly longer
but hardly longer than broad; lateral ocelli
slightly nearer each other than to eyes; face
below ocelli somewhat shining, punctures rather
fine but deep and distinct, well separated
but not sparse, becoming finer and more
sparse below, rather close on supraclypeal
area, rather coarse but shallow and quite
sparse on clypeus, very fine and quite sparse
on vertex between eyes and ocelli, margin
back of ocelli obscurely roughened; cheeks
finely striate posteriorly, rather smooth and
subimpunctate along margins of eyes, smooth,
shining and impunctate below; wings hyaline,
with the usual three submarginal cells, veins
pale testaceous, stigma somewhat more brownish;
tegulae testaceous-hyaline; legs piceous,
but the tarsi pale testaceous; scutum and
scutellum shining, obscurely metallic, punctures
fine, well separated over most of scutum,
becoming rather close and more obscure anteriorly,
those on scutellum very sparse; scuturn
with a faint, median, sulcus anteriorly;
pleura rather densely reticulate or coarsely
rugose, hypoepimeral area densely rugose;
dorsal area of propodeum rather coarsely reticulate
or substriate, lateral faces irregularly
striate below, becoming very finely so above,
posterior face transversely and irregularly
striate; abdominal terga smooth and shining,
basal tergum entirely impunctate, 2nd and 3rd
with a few exceedingly minute punctures scattered
across base, but becoming practically
impunctate toward apical margin, the quite
broad, impressed, apical areas polished and
impunctate.
MALE-Length 4 mm.; entirely black; head
slightly broader than long; eyes somewhat
convergent below; clypeus rather narrow, convex,
densely pubescent; mandibles dark basally,
becoming obscurely reddish-testaceous apically;
antennae dark, apical segments of flagellum
somewhat more piceous, basal segment considerably
broader than long, subequal to pedicel
in length, 2nd and following segments
slightly longer, but hardly as long as broad;
lateral ocelli subequally distant from each
other and eyes; face below ocelli rather dull,
punctures very fine but deep and distinct, uniformly
close, those below antennae obscured
by dense, white tomentum; vertex between eyes
and ocelli more shining, punctures minute and
indistinct, margin back of ocelli obscurely
roughened, cheeks obscurely and narrowly
striate posteriorly, becoming somewhat smoother
along margins of eyes, smooth and shining
below; wings hyaline, with the usual three
submarginal cells, veins pale testaceous, stigma
somewhat more brownish; tegulae brownishhyaline;
legs dark, but apical tarsal segments
more testaceous; scutum and scutellum quite
smooth but rather dull, sparsely punctate,
punctures on scutellum somewhat finer than
on scutum; pleura, including hyoepimeral
area, quite densely but finely rugose; dorsal
area of propodeum rather coarsely but irregularly
striate, lateral faces rather smooth
above, with a few obscure striae below, posterior
face obscurely roughened; abdominal
terga smooth and shining, obscurely metallic,
basal tergum with a few obscure, very
minute punctures scattered across middle, 2nd
and 3rd with minute, rather evenly distributed
punctures across basal half of discs, becoming
nearly impunctate toward the narrow, impl-ssed,
apical margins which are entirely impunctate;
gonostyli (fig. 113) very short and rather
robust, not exceeding penis valves, with a
hatchet-shaped, more or less excavated lobe
beneath.

Texas and Florida; May to September,
