Diagnosis. Length of fore wing 5.21– 4.56 mm; clypeus wide, with ventral margin acute; humerus distinctly projecting, carina lamellate and recurved forwards at extremity, not extending downwards ( Fig. 27 View FIGURES 27–32 ); metanotal process with apex slightly rounded ( Fig. 28 View FIGURES 27–32 ); propodeum with wide and deep excavated cavity, heart-like shape ( Fig. 28 View FIGURES 27–32 ); ground color black or reddish, scutellum totally yellow, metanotum almost, T2 with a large and anterior yellow spot ( Fig. 29 View FIGURES 27–32 ); ventral process of aedeagus curved, not projecting laterally, strongly sclerotized and weakly serrated; preapical region of aedeagus angular.
Redescription. FEMALE.Length of fore wing 5.21 mm; clypeus wide (HClp=0.72; MxWClp= 0.94;TeW=0.59; MiWClp= 0.87 mm), with ventral margin acute; tentorial pit closer to antennal socket than to eye margin; interantennal area relatively wide, approximately 2 × diameter of antennal socket; mandibles relatively short with length 0.86 × distance between eyes at vertex; occipital carina distinct, strong and salient throughout; humerus distinctly projecting, carina lamellate and recurved forwards at extremity, not extending downwards ( Fig. 27 View FIGURES 27–32 ); pronotal fovea dis- tinct; length of mesoscutum 0.93 × its width; mesepisternal groove absent; scutellum with a short but well-marked median line; metanotum triangular, length of median axis 0.69 × width of the central disk, metanotal process with apex slightly rounded ( Fig. 28 View FIGURES 27–32 ); propodeum with wide and deep excavated cavity, heart-like shape ( Fig. 28 View FIGURES 27–32 ); propodeal valvula narrow; T 1 in dorsal view with petiole short and distal margin wider and nearly straight, cup-like.
Frons, mesoscutum, scutellum and metanotum with sparser micropunctation and deeper and stronger mesopunctation, mesopleuron and T2 to T5 with distinct punctures; clypeus with short golden bristles, except on ventral margin, with elongated bristles; vertex, mesoscutum, scutellum and metanotum with more sparse and quite long setae.
Species black or reddish richly marked by yellow spots ( Fig. 27–29 View FIGURES 27–32 ); antennae ventrally testaceous or brown, dorsally black; mandibles black, clypeus almost entirely yellow, inner and outer orbit with wide bands that extend to ocular sinus, frons with a bilobate mark, two marks on vertex, small marks on pronotal carina and fovea, mesoscutum without stripes, tegulae almost entirely black, large spot on mesepisternum, scutellum yellow, metanotum partially ( Fig. 28 View FIGURES 27–32 ), propodeum without paired dorsal marks ( Fig. 28 View FIGURES 27–32 ), T1 sometimes with distal spot, extensive basal spots and narrow distal mark on T2, T3 to T5 black. Coxae, femora, tibiae brown to black; tarsi brown; wings hyaline, venation brown.
MALE. Length of fore wing 5.06 mm; eyes wide, strongly produced inwards; clypeus with ventral margin acute; tentorial pit closer to eye margin than to the antennal socket; mandible and clypeus yellow; eyes internally bordered by a band that continues to ocular sinus; anterior margin of T2 with extensive spot, yellow. Parameral spine without elongate bristles; basal angle of paramere widened, apical angle narrower ( Fig. 49 View FIGURES 45–55 ); digitus narrow, with apical margin rounded; basal process of digitus approximately acuminate; cuspis moderately filled with elongated bristles ( Fig. 52 View FIGURES 45–55 ); ventral process of aedeagus curved, not projecting laterally, strongly sclerotized and weakly serrated, laterally; preapical region of aedeagus angular ( Fig. 51 View FIGURES 45–55 ).

Remarks. Protopolybia nitida presents black color with yellow marks on the scutellum and metanotum ( Ducke, 1904; Bequaert, 1944; Richards, 1978). Three individuals from Pará, Brazil were analyzed that are structurally similar to P. nitida , but with distinct coloration; their body is brown with more yellow marks on T2. We consider this population as a variation of Ducke’s species, but additional studies are necessary to determine its real status.
