ETYMOLOGY. The name is a combination of capno - (Gr., kapnodes, like smoke, sooty, dusky) and - pteryx (Gr., pteryx, wing) in reference to the smokey nature of the apical areas of the wings.

DIAGNOSIS. Guyalna capnopteryx n. sp. can be distinguished from the majority of species of Guyalna by the lack of bronzed fore wings, hyaline basal areas of the wings, infuscation on the radial and radiomedial crossveins, are larger (greater than 30 mm) or smaller (less than 20 mm) body size, or possess completely piceous lateral sigillae. The most similar species in size with infuscated basal areas of the wings and bronzing of the apical cells of the fore wings are G. atalapae Boulard & Martinelli, 2011, G. flavantica Ruschel, 2017, G. fumea (Distant, 1883a), G. maxineae Sanborn, 2016b, G. spinula Ruschel, 2017, and G. tenebrae Ruschel, 2017. The distal apical cell bronzing is restricted to the fore wing apical cells 1–3 and fore wing apex in G. spinula Ruschel, 2017 and G. tenebrae Ruschel, 2017 rather than the distal portion of all apical cells as in the new species. The larger body size (32 mm) and bright red and brown basal area of the wings quickly distinguish G. atalapae. The contrasting pronotum color in G. flavantica and G. maxineae quickly distinguishes those species from this new species. Finally, G. fumea is green marked with piceous rather than the dark brown of this new species, the bronzing is more intense, and the mesonotal lateral sigillae are piceous in G. fumea.
Similar species in general appearance and size include Peruvian G. chrysinothrix n. sp. and the Bolivian G. dasyeia Sanborn, 2019b and G. fasciata Sanborn, 2019b. However, all these species lack the infuscation at the base of the wings found in G. capnopteryx n. sp. The lack of bronzing in the distal apical cells of the fore wing quickly distinguishes G. aurora of the Peruvian fauna.
DISTRIBUTION. The species is known from several localities within Departamento Madre de Dios, Peru.
