Females differ from Ateleute carolina , Ateleute grossa and Ateleute tinctoria by their coloration: head and mesosoma black or dark brown and metasoma mostly reddish-brown. They differ from other South American species by their brownish ovipositor sheath which is very narrowly truncate at apex, nearly pointed; head 0.48-0.51 times as long as wide; antenna (except white band) brownish with 29-32 flagellomeres; first tergite 1.70-1.77 times as long as maximum width; abscissa of Cu 1 between 1 m-cu and Cu 1a moderately inclivous, 1.10-1.17 times the length of Cu 1b; vein 2 rs-m conspicuous, 0.45-0.55 times length of abscissa of M between 2 rs-m and 2 m-cu ; vein 2 m-cu inclivous; malar space about 0.80-0.86 times as long as basal width of mandible; hind wing with distal abscissa of Cu1 strong and pigmented; Cu 1& cu-a strongly angled below middle; and body length 5.2-5.6 mm. Males can be recognized by the claspers, which have an inwardly curved profile dorsally, very narrow and pointed; vein 2 rs-m present; hind femur with 3-6 stout bristles on dorsal and ventral edge and abscissa of Cu 1 between 1 m-cu and Cu 1a inclivous, 1.00-1.20 times the length of Cu 1b. Remarks. We have linked males and females of this species using the following characters: vein 2 rs-m conspicuous, 0.45-0.55 times the length of abscissa of M between 2 rs-m and 2 m-cu ( Figs 5I, J ) and abscissa of Cu 1 between 1 m-cu and Cu 1a inclivous, forming an angle of 151-153° with Cu 1, 1.0-1.20 times the length of Cu 1b ( Figs 5I, J ), hind wing with distal abscissa of Cu 1 pigmented and Cu 1& cu-a angled clearly below middle ( Figs 5K, L ). These characters in combination differ from those of other South American species. Etymology. This species is dedicated to the Ecuadorian Shuar people, who live in the Department of Orellana, Ecuador. Phenology. Adults fly in May-June and October-November. Distribution. Ecuador and Peru. Habitat. The holotype has been collected by canopy fogging in Onkone Gare, Department of Orellana, Ecuador, in the same habitat as Ateleute huaorani .
