Commentaries. This is the only species of Neoxylocopa in which females have reddish-brown pubescence on frontal area, genal area, vertex, mesosoma, and T 1. There is few information about this species, and no information on the male. It was not possible to measure specimens.

The sonorina species group

Diagnosis. Female and male of majority of species less than 25 mm in length. Female: Frontal area of head without elevated ridges or prominences adjacent to ocelli (as in figs. 47 and 56); Clypeus: lateral areas no protuberant, clypeus densely punctate including discal area. Area below middle ocellus with a well-defined anterior frontal groove as in mexicanorun group; ocelli located below the tangent of the eyes; lateral ocelli with pits on the posterolateral region. Malar area equal than or similar to minimum diameter of F1; mandible with a notch at the level of the middle tooth (Figs. 57 and 76). Punctation of mesoscutum as in mexicanorum group. Terga as in mexicanorum group. Posterior tibiae: apex of basitibial plate as in mexicanorum group (Figs. 50, 60 and 97). Scutellum noticeably convex (not angled) (Fig. 78). Male: Integument as in mexicanorum group except terga with black bands covering only posterior margin; clypeus and labrum as in mexicanorum group; lateral ocelli below upper margin of eyes; internal distal extreme of hind tibiae with a prominent subapical projection with curved distal extreme defining a concave area (as in figs. 55 and 101), internal surface of hind tibiae with pubescence only on basal region, distal region noticeably bare.
