Diagnosis. This species can be distinguished from all other Neotropical Epirhyssaby the combination of the following characters: 1) fore wing with two blackish bands; 2) apex of hind wing yellowish; 3) pronotum and mid coxa generally blackish; and 4) hind coxa totally black.
Distribution. Bolivia; Ecuador; Peru.

Female( Fig. 4B). Fore wing length about 8–10 mm. Headwith occipital carina discernible laterally, interrupted dorsally, not joining hypostomal carina; posterior ocellus separated from eye by about 2.0 times its diameter; mandibles stout, lower tooth slightly longer than upper one; clypeus with margin concave centrally with a small apical tubercle; lower face polished with sparse yellowish setae and about 1.2 times as broad as medially long; antenna slender with 28 flagellar segments; gena highly polished with sparse setae. Mesosomawith strong epomia diverging from anterior margin of pronotum; mesoscutum with central lobe not overhanging pronotum, transverse rugae sharp, with short pubescence; mesopleuron highly polished, with scattered setiferous punctures; subalar prominence inflated; epicnemial carina ventrally reaching well above level of lower corner of pronotum; hind coxa in profile about 2.5 times as wide as deep; fore wing with cu-aproximal to base of Rs&M; first subdiscal cell broadened distally, its width near outer end about 1.8–2.0 times its basal width; abscissa of Mbetween 2rs-mand 2m-cuabout 0.3 times as long 2rs-m, Rsweakly and evenly bowed; propodeum short, highly polished with scattered long setae; submetapleural carina weak but complete. Metasomawith tergite I about 2.0–2.1 times as long as posteriorly broad, dorsally highly polished; tergite II about 1.2 times as long as posteriorly broad, highly polished, tergites III+ highly polished; ovipositor projecting beyond apex of metasoma about 4.0 times length of hind tibia. Coloration.A yellowish species; with blackish-brown markings on lateral part of face, interocellar area and transverse band from eye to eye, part of head adjacent to occipital carina infuscate, flagellum entirely blackish, extreme anterior margin of mesopleuron, scutoscutellar groove and lower part of metanotum; small median longitudinal channel of propodeum and posterior margins of tergites 1–4. Metasomal tergites 5+ brownish, ovipositor sheath dark brown. Legs yellowish, with distal parts of tarsi infuscate. Wings hyaline with strong blackish band apically; pterostigma blackish. Male.Similar to female but slender with tergite I about 3.0 and tergite II about 2.2 times as long as posteriorly broad.
Diagnosis. This species can be distinguished from all other Neotropical Epirhyssaby the combination of the following characters: 1) tergite I polished wrinkled basally; 2) propodeum highly polished, without median longitudinal depression; 3) fore and hind wings with blackish band apically; and 4) occipital carina not joining hypostomal carina. Epirhyssa cuscoensis sp. n.resembles E. daedalaPorter, but it can be distinguished by the shorter tergite I and clypeus with weak median tubercle. Biological notes. It has been found in the tropical Andes, nothing is known about its hosts.
Etymology.The name cuscoensisrefers to the Peruvian Andean region of Cusco, the capital of the Inca Empire.
Distribution. Peru.
