Diagnosis. FEMALE. Fore wing with ca. 6.5 mm; occipital-genal margin absent dorsally from side to side, very weak laterally; eyes with sparse bristles visible at high magnification; clypeus with rounded apex, much wider than high, transverse (HCLP/WCLP—0.79) (Fig. 1); pronotal carina absent; prominence in front of fovea moderately elevated; first metasomal segment quite elongated and narrow at apex. Proportional ratios: LSI/HMP—1.10; LSI / WT1_AP—2.59; WT1_AP / BA—2.45. MALE. occipital-genal margin obsolete; clypeus vestiture with very dense appressed pale pubescence; first tergum and sternum with very short erect bristles, more numerous on sternum; remainder of metasoma with whitish hairs, few in number, in addition to some short erect bristles.

Distribution. Brazil: Amapá *, Amazonas, Bahia, Pará, Roraima; Suriname; French Guiana; Peru.
Remarks. Polybia belemensis is the species with the narrowest first metasomal segment within the P.occidentalis group. It was described by Richards (1970) based on females from the Brazilian Amazon (Belém, Pará) (holotype and 48 paratypes) and Suriname (14 paratypes). Later, Richards (1978) described the subspecies P. b. brevitarsus based on females from Panama and Costa Rica, which we consider a distinct species (see below). Polybia belemensis as here conceived (i.e., P. b. belemensis) has been previously recorded from Brazil, Peru, Suriname and French Guiana. Here we present the species diagnosis for females and the first description of the male. Unfortunately, all type material in Brazil (MNRJ) has been lost in a 2018 fire, but one paratype in the NHM was examined (by O. T. Silveira). Furthermore, considering that original description by Richards (1970) is clear enough and that we examined many specimens from the type locality, the species identity can be considered unproblematic.
The analyzed specimens from Peru, borrowed from MZUSP, were initially identified as P. diguetana probably by O.W. Richards. Occurrence of P. belemensis in Peru had already been mentioned in Rasmussen & Asenjo (2009), based on specimen(s) from the department of San Martin (probably housed at Museo de Historia Natural de Lima) identified by J. M. Carpenter. The department of San Martin ranges from very high areas in the Andes to forested lowlands along its eastern border shared with the department of Loreto. The label of the MZSP specimen just says “ Peru ”, and we tend to believe that it also has been collected in some place in the Peruvian Amazon.
Andena & Carpenter (2014) recorded P. belemensis from the Brazilian Northeastern region, Bahia state (three localities), and these seem indeed rather unexpected places to find the species. However, we have no reason to doubt correctness of identification, and this seems to be one more case of an “Amazonian” wasp species rediscovered in areas of eastern Atlantic Forest.
In the MPEG collection there are six nests with characteristics similar to those mentioned by Richards (1978), which include a “chocolate-brown” color with a striped and striated envelope, having on average the same proportions; most of them have a non-functional comb, on the top, and two other functional combs; cell diameter ca. 3.5mm; comb diameter ca. 4.5 cm
