FEMALE-Length 6 mm.; head and thorax
black, abdomen ferruginous, becoming blackened apically; head somewhat broader than
long; eyes very slightly convergent below; clypeus only slightly convex; labrum broadly
rounded, dark; mandibles with a distinct, inner, subapical tooth, reddish-testaceous, becoming somewhat darker at base and more
reddish at tip; antennae blackish at base,
flagellum dark brownish-piceous, basal segment broader than long, 2nd and following
segments about as long as broad; lateral
ocelli subequally distant from eyes and each
other; face below ocelli very closely and rather
coarsely punctate, punctures becoming slightly more widely separated below, but obscured by pale tomentum, those on supraclypeal area very fine and close, those on clypeus
more coarse and deep but quite close even
apically; vertex between eyes and ocelli somewhat shining, punctures very fine but deep and
distinct, slightly separated, hind margin becoming obscurely rugose; cheeks above rather
dull, very finely rugoso-striate, lower surface
somewhat smoother but rather dull; wings
hyaline, with the usual three submarginal cells,
veins testaceous, stigma somewhat more
brownish; tegulae testaceous-hyaline; legs
piceous basally, becoming somewhat moEe
brownish-testaceous on tarsi: scutum and scutellum shining, punctures deep and distinct,
rather coarse and well separated over scutum
medially, becoming rather close between notaulices and tegulae and narrowly rugosopunctate across anterior margin, those on scutellum very fine and sparse; pleura dull,
coarsely rugose anteriorly, becoming rather
finely striate below posteriorly, the hypoepimera1 area rather smooth, with a few shallow,
obscure punctures; dorsal area of propodeum
completely, coarsely and quite regularly striate, lateral faces finely roughened, becoming
rather coarsely and irregularly rugose below
posteriorly, the posterior face coarsely rugosostriate; abdominal terga smooth and shining,
basal tergum impunctate and tergum 2 with only a very few, scattered and wry sparse, minute punctures toward base, tergum 3 with
somewhat closer but still very minute and
sparse punctures, apical margin of each tergum broadly impressed, yellowish-hyaline
MALE-Length 5 mm.; head and thorax
black, abdomen black, more or less suffused
with ferruginous toward base; head slightly
broader than long; eyes rather strongly con- vergent below; clypeus slightly convex; mandibles dull ferruginous, becoming darkened at
base; antennae black basally, flagellum more piceous, basal segment about as broad as long,
following segments slightly longer, but length
not much exceeding breadth, entirely simple;
lateral ocelli subequally distant from eyes and
each other; lower half of face more or less
obscured by pale pubescence, clypeus partially
exposed, punctures very fine and quite close,
face above antennae dull, punctures fine and
densely crowded, becoming more distinctly separated on vertex between eyes and ocelli, hind
margin obscurely roughened and dull; cheeks
finely striate except narrowly along margin of
eye, the lower sur*ace rather smooth and shining; wings subhyaline, with the usual three
submarginal cells, veins testaceous, stigma
more piceous; tegula yellowish-hyaline; legs
black, only the apical tarsal segments being
at all brownish; scutum and scutellum shining
between deep, distinct punctures, these rather
fine, rather widely separated over most of scu- tum, and somewhat closer between notaulices
and tegulae, becoming obscure along anterior
margin, those on scutellum very fine and
sparse; pleura densely rugose, more finely
reticulate anteriorly, hypoepimeral area relatively smooth, somewhat shining, with a few,
shallow, obscure punctures; dorsal area of
propodeum rather coarsely and irregularly
striate, lateral faces dull but rather smooth
anteriorly, becoming irregularly rugoso-striate
posteriorly, posterior face more coarsely reticulate; abdominal terga smooth and shining,
basal tergum practically impunctate, tergum
2 with very fire and rather close punctures
toward base on each side, becoming very
sparse medially and apically, tergum 3 more uniformly, finely punctate over most of disc,
apical margins of all terga rather broadly impressed, entirely impunctate, concolorus with
remainder of discs; gonostyli (fig. 117) barely
exceeding tips of penis valves, slender and
very slightly constricted at base, with a few
very short inconspicuous setae.
