Diagnosis. This species can be easily recognized by the posterior margin of mesoscutellum with a deep, semicircular emargination, which is at least twice as broad as the width of the axilla, and the base of the antennal scape covered with short erect setae (0.5–0.6× width of scape). It resembles N. pilosa in the mesoscutellum with a broad emargination and the base of the antennal scape with short setae. However, in that species the mesoscutellar emargination is narrower (at most 1.7× width of axilla), the facial pubescence denser and obscuring the integument, and the antennae are usually lighter in color than in N. camargoi .

Description. Male. As described for the female (see Rasmusen & Gonzalez, 2017), except as follows: total body length 3.8–4.3 mm; head width 1.7–1.8 mm. Intertegular distance 1.2–1.4 mm; forewing length 3.9–4.0 mm. Malar area about 0.4× width of F3; intertorular and torulorbital distances, each as long as torular diameter; interocellar distance 1.7× OD, 2.0× longer than ocellocular distance; ocelloccipital distance about as long as OD; scape 3.8× longer than wide. Mesoscutellum with median emargination on posterior margin large, semicircular, about 3.0× broader than long, tooth lateral to emargination obtuse (less acute than worker), 2.1× wider than scape. Metasomal S5–8 and genital capsule as in figures 1d–h.

Color black, except as follows: dark reddish brown on labrum and mandible, except basally; yellow on lateral margin of mesoscutum, axilla, apical tooth of mesoscutellum, outer surfaces of pro- and mesotibiae basally, and metatibia except apically; tarsi light reddish brown. Veins and pterostigma brown.

Distribution. Ecuador (Cotopaxi, Esmeraldas, Loja, Pichincha) and Colombia ( Fig. 2 View FIGURE 2 , Table 1 View TABLE 1 : Antioquia, Chocó, Nariño, Risaralda, Valle del Cauca).

Comments. Rasmussen & Gonzalez (2017) described this species from Ecuador and indicated wing coloration (forewing membrane and veins basally light reddish brown contrasting with apex dark grayish brown) as one of the diagnostic features. However, such a wing coloration varies among Colombian specimens, even from the same locality (e.g, Tumaco, Nariño). In some, the wings are as in the Ecuadorian specimens whereas in others these are uniformly dark grayish brown. Therefore, herein we tentatively assigned these Colombian specimens to C. camargoi . Future studies should assess the species status of these specimens because wing membrane color is a good morphological feature to distinguish species in Meliponini and we were not able to compare the male genitalia of the Ecuadorian specimens of C. camargoi with those from Colombia.
