Key to species groups of Euglossella

NOTE: This revised and expanded key to species groups within Euglossella supersedes the one presented by Hinojosa-Díaz & Engel (2011a) as their original ‘ viridis ’ group is here split into two distinctive groups of species.

1. Pronotal dorsolateral angle orthogonal to acute, slightly projected; mesoscutellum with a large central concavity, creating two mid-lateral cusps, clearly noticeable in males ( Figs. 117, 133), in females present in depressed contour of mesoscutellar tuft ( Figs. 119, 139); lower interorbital distance at least 1.10 times as wide as upper interorbital distance; malar area longer than diameter of mid-flagellar articles ................................................................................ mandibularis group
