Diagnosis. Body length 4.5–5.0mm. Bristles black and vibrissa narrow. Hind fronto-orbital approximately as long as anterior fronto-orbital. Colour similar to that of H. kinetrolicros , although base colour of head and thorax paler; male with pleuron brown on anterior face (remainder yellow), basal band on fore basotarsomere and sometimes apex of fore tibia white, and mid and hind femora with faint brown medial mottling; female with fore femur yellow with apex brown, and mid and hind femora brown at apex and base. Vein R2+3 curved anteriorly, and wing with apex, medial band, and faint distal portion of first radial cell dark. Male genal process at most with two segments with basal segment long and broad and apical segment minute and ovate; sometimes highly reduced or entirely absent (only entirely absent in one tentatively-identified male known only from photo ( Fig. 1 )). Epandrium with anterodistal margin produced. Surstylus with bristles long and thin and anterodistal corner with small rounded process; surface sometimes wrinkled with distal margin irregular. Apex of ejaculatory apodeme exceptionally wide.

Pregonite strongly arched. Spermatheca subcylindrical with apex narrower and basal half with minute transverse wrinkles.

Distribution. Bolivia, Costa Rica, Ecuador, Peru. Previously known only from Peru.

Comments. We have recently collected one male and one female from Bolivia (listed above) that differ from other known Hendelia mirabilis in that the fore femur is brown basally and the female face and gena are yellow. Furthermore, the male genal process ( Figs 7–10 ) is small, acute and composed of one segment nearly equal in width to the eye when viewed anteriorly. The male genitalia ( Figs 14–16 ) are similar to those of the holotype (and different from those of H. kinetrolicros and H. masneri ) in that the anterodistal margin of the epandrium and surstylus are produced, the distomedial surface of the surstylus is covered with minute longitudinal wrinkles and the hypandrium has one long and three short bristles. A second male from Bolivia deposited in CSCA ( Figs 7–10 ) has a nearly identical genal process.

The only known male from Costa Rica (photographed in Monteverde, but not collected) ( Fig. 1 ) is distinct from other known males in that the genal process is entirely absent, there is an ill-defined notal stripe, the scutellum appears to be brown dorsally, the pleuron is yellow except for the dark subnotal stripe and R2+3 does not appear to be sinuate. Despite this, the male is here tentatively considered to be Hendelia mirabilis since there is a white subbasal band on the fore basotarsomere, the mid and hind tibiae are brownish and the frons is dark with the posterior corner yellow.
