REMARKS. The Peruvian specimen chosen as the holotype retained the original coloration to the greatest degree as did a number of specimens collected in Peru. For this reason, the fact the majority of specimen originated in Peru, and Peru is centrally located within the distribution of the species, a Peruvian specimen was chosen as the holotype over a Bolivian example. The green disappeared in what was to be the holotype when placed in the humidity of the softening jar for a few hours. Another from that series was then chosen and was not exposed to the conditions of the softening jar to retain the original coloration. There is a range of coloration patterns and the distribution of pile on the abdomen within the type series. The chemical alteration has led to ochraceous replacing green in many specimens and the pile has been removed partially or completely from the abdomen in several specimens. When present, the pattern in the abdominal pile and body size make the species easy to distinguish from the remaining Bolivian species of Guyalna .

ETYMOLOGY. The name is a combination of poly – (Gr., polys, many) and – paga (L., pagus, country) in reference to expansive distribution of this new species being found in multiple countries.

DESCRIPTION. Ground color of head and thorax castaneous marked with piceous, tawny and green, abdomen castaneous and piceous. The green coloration has faded or been chemically altered by the light traps to ochraceous in many specimens. Green is considered the original color over ochraceous the majority of Peruvian series is colored in this manner with only a few exhibiting the ochraceous markings. I will use green instead of ochraceous in the description with the understanding that green can be replaced by ochraceous.

Head. Head wider than mesonotum almost as wide as lateral angle of pronotal collar, green with transverse piceous fascia beginning on anterolateral vertex including posteromedial corner of supra-antennal plate encompassing the entire frons and extending and encompassing the ocelli, mark does not reach anterior margin of vertex or supra-antennal plate, mark margined posteriorly on vertex with castaneous reaching posterior head on dorsal midline, castaneous replaces green in some paratypes, piceous posterior to eye. Head covered with dense, short silvery pile dorsally, longer posterior to eye. Ocelli red, rosaceous in some paratypes, eyes dark castaneous, ochraceous in some paratypes. Ventral head piceous except green on gena next to lorum and green anterior quarter of lorum, green on gena reduced some paratypes, green extending from dorsal vertex medial to eye in some paratypes.

MEASUREMENTS (MM). N = 10 males or 10 females, mean (range). Length of body: males 18.95 (18.0–20.05), females 18.21 (17.5–20.35); length of fore wing: males 25.45 (23.6–26.75), females 26.08 (25.0–26.9); width of fore wing: males 8.23 (7.85–8.55), females 8.23 (7.9–8.55); length of head: males 2.70 (2.65–2.75), females 2.75 (2.65–2.9); width of head including eyes: males 7.34 (6.95–7.65), females 7.34 (7.05–7.6); width of pronotum including suprahumeral plates: males 7.39 (7.15–7.7), females 7.36 (7.05–7.65); width of mesonotum: males 6.19 (5.6–6.5), females 6.36 (6.1–6.7).

DIAGNOSIS. The majority of species of Guyalna can be distinguished from Guyalna polypaga n. sp. by exhibiting bronzed fore wings, infuscated basal areas of the wings, infuscation on the radial and radiomedial crossveins, larger (greater than 20 mm) or smaller (less than 16 mm) body size, or completely piceous lateral sigillae. The most similar species in Bolivia is G. platyrhina which can be distinguished by its smaller body size, the flattened postclypeus when viewed from the side, the piceous markings on the dorsal abdominal midline and the lack of abdominal pile found in G. polypaga n. sp. Other potential species of similar size and coloration are G. cuta ( Walker, 1850) , and G. nigra Boulard, 1998 and this new species shares characteristics of both of the species. Guyalna cuta can be distinguished from this new species by the more stout body, the complete transverse piceous fascia on the dorsal head connecting to the piceous margin of the eye, the lack of piceous markings within the transverse grooves of the ventral postclypeus, the absence of the piceous mark on the dorsal midline of the pronotal ambient fissure, the male opercula are larger almost meeting medially, the posterior margin of the female operculum is transverse with a strong curve to the medial terminus, the pygofer basal lobes have a triangular terminus, the uncal dorsal crest extends prior to the dorsal terminus of the uncus, and the notch in female sternite VII is smoothly curved appearing semicircular. The final similar species is the slightly larger G. nigra but it can be distinguished by the complete transverse piceous fascia on the dorsal head, the dorsal opening to the timbal cavity is angled anteriorly at the dorsal terminus and at the extension of the timbal cover connected by a straight region along the opening to the timbal cavity rather than being smoothly curved along the entire opening to the timbal cavity, the male opercula are larger almost meeting over abdominal sternite I but barely cover the tympanal cavity in the new species, the abdominal tergites are mostly piceous, the series of castaneous spots on the midline of the female abdominal sternites rather than the ochraceous circle formed on the abdominal sternites of the new species, the basal pygofer lobes have a triangular, recurved tip rather than the semicircular terminus of the new species, the uncal dorsal crest is longer, the lateral branch of the uncus terminates in a pointed recurved tip, and the posterior margin of female sternite VII is almost transverse rather than angling posteriorly as in this new species. Although G. nadae ( Gogala et al. 2015) has some similar markings, it is significantly smaller with body lengths less than 13.6 mm.

DISTRIBUTION. The species has an expansive distribution with members of the type series being collected in Bolivia, Brazil, Colombia, Ecuador and Peru.
