Oragua bousemani, NEW SPECIES 
FIGURE 512, PAGE 629 
Length of male 8.0 mm, of female 8.7 mm. Head with median length of 
crown slightly more than four-tenths interocular width, and from one-fourth 
to slightly less than three-tenths transocular width; ocelli located on a line be- 
tween anterior eye angles, surface of crown coarsely punctate; antennal ledges 
with anterior margins concave; transclypeal suture obsolete medially. Pro- 
notum, scutellum, and portion of forewing basal to apical cells, punctate; 
apical cells membranous with base of membrane abruptly delimited, base of 
fourth apical cell located more proximally than base of third. Male pygofer 
with macrosetae on apical two-thirds; plates not extending posteriorly as far 
as pygofer apex, each with uniseriate macrosetae; style extending posteriorly 
almost as far as apex of connective, apex broad, truncate, and slightly con- 
cave, with preapical lobe weak; aedeagus with very short dorsal apodemes, 
shaft in lateral view curved dorsally through 90° near its apex; paraphyses 
with stalk much shorter than rami which are slender, tapering, gradually 
divergent and minutely sculptured in their apical one-third. Female ab- 
dominal sternum VII with posterior margin tapered to acute apex, without 
posterolateral lobes. 
Crown and pronotum dull yellow, heavily and irregularly marked with 
black, scutellum with a basal black spot on each side; forewing with 
coriaceous portion marked as on anterior dorsum, but with a larger dull 
yellow spot in inner anteapical cell; face with ground color as on anterior dor- 
sum, with muscle impressions on clypeus and median additional irregular 
markings on clypeus and clypellus black; thoracic pleura, venter, and legs dull 
yellow to dull ivory. 
Holotype male, mouth of Rio Ibare, Rio Mamore, Dept. Beni, Bolivia, 
August 18, 1965 (J. K. Bouseman), and one female, Saavedra Experiment 
Station, Dept. Santa Cruz, Bolivia, December 28, 1959 (R. Cumming) 
(OSU). 
O. bousemani, n. sp., is similar to O. alvarengai, n. sp., in many respects, but 
has no orange markings. The aedeagus is distinctive within the genus.

Length of male 10.1-10.3 mm, of female 10.7 mm. Head with median 
length of crown varying from slightly more than one-third to more than four- 
tenths interocular width and from one-fifth to more than one-fourth trans- 
ocular width; ocelli located on a line between anterior eye angles, surface of 
crown densely punctate; antennal ledges with anterior margins convex; trans- 
clypeal suture obsolete medially. Pronotum and scutellum densely punctate; 
forewing with membrane including almost all of apical cells, not sharply de- 
limited from remainder of wing, base of fourth apical cell located more proxi- 
mally than base of third, wing surface punctate before apical cells. Male py- 
gofer with macrosetae of several sizes and with interspersed microsetae all
