ventral processes joined very broadly to shaft

Aedeagus with narrow lateral protuberance along dorsal margin of shaft, 
ventral processes more narrowly joined to shaft 
robusta (Walker) (fig. 759) 
16. Aedeagus in lateral view with shaft broader and curved slightly dorsal- 
ly (fig. 760f); pygofer processes in caudoventral view short, not at- 
taining median line and similar to those of blanchardi (fig. 753p); fore- 
wing with large white markings on disk of corium 
monticola (Fowler) (fig. 760) 
Aedeagus in lateral view with shaft narrow, not curved (fig. 761/); py- 
gofer processes in caudoventral view slender and more elongate, at- 
taining or crossing median line (fig. 761); corial markings consisting 
of dots, and occasionally of larger white markings near and parallel

Length of male 5.7-6.0 mm, of female 5.6-5.9 mm. Head with median 
length of crown varying from slightly more than four-tenths to slightly more 
than six-tenths interocular width and from one-fourth to slightly more than 
one-third transocular width; antennal ledges with anterior margins rectilinear 
and vertical in lateral view; clypeus broadly convex, not flattened medially, 
muscle impressions distinct. Pronotum with posterior portion not transversely 
striate; scutellum without transverse striae behind transverse sulcus; forewing 
with membrane including all of apical cells except basal portion of fourth; 
veins distinct. Male pygofer with apex strongly convex, posteroventral margin 
concave, with a number of macrosetae arranged in anteapical diagonal group, 
and a few located submarginally near posterodorsal margin; plate with 
numerous dispersed microsetae and a few uniseriate macrosetae in apical half; 
style not extending posteriorly nearly as far as apex of connective, with an an- 
teapical mesal angular tooth, apex obliquely truncate; aedeagus without 
processes, with shaft very short, curved slightly posterodorsally; paraphyses 
with the two arms arising at asymmetrical locations from base, which is me- 
dian. 
Color of crown, pronotum, and scutellum yellowish tan, disk of pronotum 
somewhat darker; crown with median line (often incompletely) narrowly 
black, with a semicircular black areole on each side of apical margin, partly 
enclosing a black spot and giving off two narrow parallel black stripes that ex- 
tend posteromesally to the basal margin, thus forming a narrow rectangular
