Field Notes. My specimens of A. paitensis were collected in 
flight, usually not far off the ground in grassy areas near water. I 
have not taken the species on Baceharis.

Fore wing 6.0-16.0 mm long. Coloration metallic green, blue, 
purple, golden or often varicolored metallic; no pale markings on 
mesosoma and in only 1 species with white on gaster; wings brown- 
ish to black, with a metallic lustre, never contrastingly light and 
dark banded. Flagellum moderately long and slender, scarcely flat- 
tened below toward apex in female, in male with tyloids well devel- 
oped on some segments and varying from linear to elliptic or ovoid, 
its 1st segment 3. 5-5. 5 as long as deep at apex in females and 2. 2-3. 7 
as long as deep in males. Clypeus: in profile almost flat to moder- 
ately high convex or, rarely, subpyramidal; its apical margin 
straight to rather strongly convex, edentate, occasionally a little 
produced and feebly bilobed on meson. Occipital carina: sharp but 
not strongly raised; joining the sharp but not much raised hypo- 
stomal carina below. Malar space 0.70-1.8 as long as basal width of 
mandible. Pronotum: submarginal groove broad and variably 
strong; epomia usually sharp in scrobe but never strongly turned 
mesad or produced into a plate-like structure above. Mesoscutum: 
notauli usually strong, extending 0. 3-0.9 the length of mesoscutum; 
surface mostly smooth and shining, sparsely to densely but not 
grossly punctate, never strongly wrinkled or extensively mat. Meso- 
pleuron with speculum usually smooth and shining but occasionally 
more or less puncto-reticulate; surface otherwise wholly or in part 
finely to grossly and usually reticulately wrinkled; no projection or 
ridge on prepectus below. Fore tibia never inflated. Hind coxa with 
a sharp and strong subvertical groove externo-ventrally near base.
