Comments. This species is similar to A. juliela by having the head wider than long; the mandible with one tooth; the notaulus complete; the mesoscutum-mesoscutellar suture weakly arched, wide and deep; the hypopygium with flap and posterior margin concave. However, A. kelsiela has the metapostnotum almost all polished, being only strigate anteriorly and metapostnotal median carina absent, whereas A. juliela has the metapostnotum irregularly strigate and metapostnotal median carina present.

Distribution. Neotropical ( Trinidad and Tobago, Brazil).
