FIGURE 1. Worker of Trigona ( Nostotrigona ) recursa Smith, 1863 . A —Lateral habitus. B —Head, frontal view. C —Dorsal habitus. D —Metatibia and metabasitarsus. Scale bars: 1 mm. Diagnosis: Integument predominantly black. Clypeus with abundant silvery decumbent hair on the lower paraocular area, and sparse and slightly brown on the upper half of the face. Mandible dark brown in the basal half and reddish-brown in the apical half, with five teeth. Clypeus and scape with setae of length approximately 0.14 mm (about 0.9× the diameter of the scape). Clypeus with wide distance between the epistomal suture and inferior tangent of the antennal socket, approximately 0.7× the scape diameter. Scape reddish-brown dorsally, and slightly brownish ventrally and basally on the sixth. Malar area approximately 0.8× the diameter of the scape. Carina post-ocellar strongly elevated. Vertex with setae of length approximately 0.22 mm , about 1.5× the diameter of the scape. Mesoscutum with setae of length approximately 0.22 mm , about 1.5× the scape diameter, scutellum with longer setae ( 0.38 mm ), approximately 2.5× the scape diameter. Metatibia relatively narrow and shallow, approximately 3.1× longer than wide. Metabasitarsus with anterior and posterior margins subparallel, apex slightly concave. Wing membranes hyaline. Veins C, R and M+Cu slightly darkened, the other veins and pterostigma brownish. Metasoma elongated, approximately 2× longer than wide. Total body length approximately 5.3 mm . Geographic distribution ( Fig. 8 ): Brazil ( Ceará , Goiás , Maranh„o, Mato Grosso , Minas Gerais , Piauí , S„o Paulo, Tocantins ). Biological note: T. recursa builds underground nests, and its nest defense behavior is not aggressive ( Rasmussen & Camargo 2008 ). According to Jarau et al. (2003) , this species has a facultative necrophagous behavior. Examined type material: One worker ( lectotype ) was examined through of digital image.

As referred to earlier, it is possible that specimens reported in the literature as Trigona recursa Smith in the Brazilian Amazon are actually several undescribed species, as corroborated by Camargo et al. (2013) .
