Taxonomic discussion.

Females differ from Ateleute carolina  , Ateleute grossa  and Ateleute tinctoria  by their coloration: head and mesosoma entirely black and metasoma anteriorly dark brown and posteriorly reddish-brown. They differ from other South American species by their brownish ovipositor sheath, moderately truncate at the apex; head 0.48 times as long as wide; antenna (except white band) dark brown with 30 flagellomeres; first tergite 1.65 times as long as wide posteriorly; abscissa of Cu1 between 1m-cu and Cu1a 1.25 times the length of Cu1b; vein 2rs-m obliterated or at most 0.10 times the length of abscissa of M between 2rs-m and 2m-cu; vein 2m-cu vertical; malar space about 0.65 times as long as basal width of mandible and body length 5.9 mm. Males differ from other species by their claspers being transversally and widely truncate; vein 2rs-m obliterated and hind femur with numerous conspicuous stout bristles.

Remarks.

We have linked males and females of this species using the following characters: vein 2rs-m vein obliterated or at most 0.10 times the length of abscissa of M between 2rs-m and 2m-cu (Figs 5C, D) and the abscissa of Cu1 between 1m-cu and Cu1a inclivous, forming an angle of 140°-150° with Cu1, 1.20-1.40 times the length of Cu1b (Figs 5C, D). This combination of characters differs from those of other South American species.
