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
); metanotal process with apex slightly rounded (
Fig. 28
); propodeum with wide and deep excavated cavity, heart-like shape (
Fig. 28
); ground color black or reddish, scutellum totally yellow, metanotum almost, T2 with a large and anterior yellow spot (
Fig. 29
); 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
); 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
); propodeum with wide and deep excavated cavity, heart-like shape (
Fig. 28
); 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
); 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
), propodeum without paired dorsal marks (
Fig. 28
), 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.

; 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
); digitus narrow, with apical margin rounded; basal process of digitus approximately acuminate; cuspis moderately filled with elongated bristles (
Fig. 52
); ventral process of aedeagus curved, not projecting laterally, strongly sclerotized and weakly serrated, laterally; preapical region of aedeagus angular (
Fig. 51
).

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.
