considerably broader than long; eyes very
slightly convergent below; clypeus rather
broadly convex; mandibles black basally, be coming reddish apically; antennae black, scape
very short, basal segment of flagellum about
as broad as long, 2nd nearly twice this length,
remainder of flagellum rather strongly moniliform, the more apical segments with basal,
densely pilose, very short, semicircular facets
beneath; lateral ocelli subequally distant from
eyes and each other; lower portion of face obscured by dense, white pubescence, surface of
clypeus partially exposed, punctures rather
fine and very close throughout, area above antennae dull, punctures deep and distinct but
rather coarse and very close, becoming somewhat more distinctly separated on vertex between eyes and ocelli, hind margin becoming
more reticulate, cheeks finely rugoso-punctate
above, becoming rather distinctly and coarsely
striate below, only a very restricted portion of
ventral surface being smooth and shining;
wings subhyaline, with the usual three submarginal cells, veins and stigma brownishtestaceous; tegulae yellowish-hyaline; legs
blackish, only the apical tarsal segments becoming brownish; scutum and scutellum somewhat shining between coarse and deep punctures, these well separated in center of scutum, but not sparse, becoming rugoso-punctate
along anterior margin, scutellum well covered
with irregular, deep and close punctures;
pleura coarsely reticulate; dorsal area of propodeum coarsely reticulate medially, becoming
more regularly striate laterally, lateral faces
striate anteriorly, becoming reticulate posteriorly, and posterior face coarsely reticulate; abdominal terga shining between rather
coarse, deep and distinct punctures, these quite
close over discs of each tergum, only the rather narrow, apical, impressed areas impunctate,
these very slightly reddened along rims; gonocoxites rather strongly excavated on dorsal
surface, the gonostyli robust, compressed, inner surface somewhat excavated, with a slender apical projection which is well covered
with setae, and with a broad, submembraneous,
inner lobe, considerably exceeding apex of
penis valves. (similar to dichrous, fig. 117).
