width, crown in lateral view not concave. Pronotum and forewings as in A. 
fuscinula, n. sp.. Male pygofer slender and elongate with posterodorsal margin 
produced posteriorly into a tapering, acute process and exceeding pygofer 
apex which is a narrow and strongly convex lobe scarcely wider than ad- 
jacent process, with two macrosetae near posteroventral margin near its mid- 
length; plates slender and triangular, narrowed in basal half, with uniseriate 
setae in basal two-thirds of their length, otherwise as in fuscinula; style with 
lateral lobe near midlength, connective Y-shaped with arms more divergent 
than in fuscinula; aedeagus with a pair of slender processes arising laterally on 
shaft near its base, extending dorsolaterally, each bifid apically with the 
longer ramus extending posteroventrad, with pair of larger processes arising 
ventrally on shaft distal to bases of the preceding, extending dorsally, 
broadened and giving off several branches at apex, the apices not sym- 
metrical, without processes arising near decurved apical portion of shaft. Fe- 
male unknown. 
Color of crown and anterior portions of pronotum shining castaneous, with 
a pair of black spots near base on crown; remainder of pronotum, scutellum 
and forewings duller brown, the forewings translucent, marked with small 
white spots and a larger pale spot on corium opposite mid-clavus, longi- 
tudinal veins of corium and margins of apical cells reddish; clypeus marked as 
in fuscinula, apex of clypellus and genae pale; thoracic pleura and legs tan. 
Holotype male, Camp Curiche, Choco Dept., Colombia, 1967 (OSU). 
A. chocona, n. sp., is similar in form to A. mucidula (Jacobi) and A. incompta, 
n. sp., in the form of the pygofer. The male plates, styles and connective, not 
illustrated, are similar to those structures in A. smidti (Metcalf) (fig. 531). The 
distinctive aedeagus of chocona and the characters used in the key will serve to 
distinguish it from other species in the genus.

FIGURE 529, PAGE 649 
Length of male 7.6-8.0 mm, of female 6.9-7.6 mm. Head with median 
length of crown varying from slightly less than one-half to almost six-tenths 
interocular width, and from three-tenths to slightly more than one-third trans- 
ocular width, crown in lateral view not concave across ocelli. Pronotum with 
width equal to or less than transocular width of head, forewings with texture 
translucent. Male pygofer as in A. chocona, n. sp., plates slender and tri- 
angular, narrowed in basal halves, weakly fused basally, not extending 
posteriorly as far as pygofer apex, with macrosetae uniseriate on broader 
basal portion on each plate; style with a lateral lobe at midlength of shank; 
connective broadly U-shaped; aedeagus curved slightly posteriorly in its apical 
half, with a pair of short aciculate processes arising on ventral margin of shaft 
near base, and a pair of short variable dorsal processes arising anteapically 
and directed ventrally, without any processes extending beyond apex of shaft. 
Female abdominal sternum VII with posterior margin gradually tapered to 
broad weak apical lobe that is broadly, shallowly concave at middle.
