Variation. Some females may present wings more bluish, or bluish with the papillate region with greenish iridescence.

Distribution ( Fig. 140 View FIGURES 136–140 ).

Commentaries. The type specimen described by Cockerell as X. wilmattae ( AMNH _IZC 00323995) was reviewed but lacked antennae and the final tarsi and claws of the middle and posterior legs. Xylocopa wilmattae is the largest species with convex scutellum, and thus may be confused with species of the frontalis group, but may easily be distinguished by the absence of frontal projections. Males in this species do not present a prominent curved subapical projection on the internal distal extreme of the posterior tibia, and it is the only species with thick external tibial spurs on the middle and posterior tibias.
