horizontal than portion of clypeus above the angularity. Pronotum not 
sculptured, scutellum not swollen behind transverse sulcus, forewing with 
bases of all anteapical cells proximal to claval apex. 
Male pygofer with posterior margin regularly convex, without processes, 
with numerous macrosetae on posterior two-thirds; plates with uniseriate 
macrosetae; style extending posteriorly beyond apex of connective, without a 
lateral lobe; aedeagus with shaft slightly decurved, without processes; 
paraphyses with stalk much longer than rami which are truncate apically and 
subparallel in their apical portions. 
Crown amber, with at least a small black spot on posterior margin behind 
each ocellus, often (holotype) with the ocelli black-bordered, and in some 
specimens with a single median or a pair of near-median spots before ocelli; 
pronotum with anterior marginal area concolorous with crown, irregularly 
marked with a few black spots, remainder purple; scutellum amber, with a 
pair of small, laterobasal spots and in some specimens (holotype) with a me- 
dian basal black spot. Forewing opaque, gray with a dull orange costal stripe 
curving mesad apically to form apical border of gray portion; bases of an- 
teapical cells dark purple or not (holotype); face yellow (holotype) to gray 
with poorly delimited and inconstant black markings; thoracic pleura 
pruinose; legs yellow to gray, in some specimens with apical portions 
darkened. 
Holotype and one additional male, Ptari-tepui, 30 mi. North of Kavanayen, 
Venezuela 1,800 m., August 14-16, 1970 (R. E. Dietz IV); one male, same 
data except August 17-19, 1970; seven males, Bolivar, Kavanayen, Venezuela 
1,000 m., August 8, 1970 (R. E. Dietz IV) (USNM). 
K. dietzi, n. sp., may be distinguished from other species of Kogigonalia by 
the color pattern, the profile of the face, and the form of the aedeagus. 
I take pleasure in naming this species for the collector, R. E. Dietz IV.

Length 10.5-11.3 mm. 
Head well produced, median length of crown varying from six-tenths to 
slightly less than eight-tenths interocular width and from four-tenths to one- 
half transocular width, anterior margin broadly rounded in dorsal view, 
without a carina at transition from crown to face, ocelli located on a line be- 
tween anterior eye angles, each approximately equidistant from adjacent an- 
terior eye angle and median line of crown, crown with a transverse concavity 
across ocelli, without a median fovea and without sculpturing or setae, lateral 
clypeal sutures extending onto crown and attaining ocelli; antennal ledges not 
protuberant, in lateral view with anterior edges oblique and convex or rec- 
tilinear; clypeus convex medially, muscle impressions distinct or not, trans- 
clypeal suture obscure medially, clypellus not strongly produced but in pro- 
file with its lower portion more nearly horizontal than its upper portion.
