(Figs 2 F, 4D)
Material examined. Type material: Holotype, male (FSCA) Peru, Tingo María, 620 m., X-5/12 -1964, C.C. Porter.
New material examined: Female (MEKRB) Peru, La Merced, Fundo La Genova, AECID A/013484/07, 16–30.VIII.2008.
Female, (CEUA) Peru, Malaise 2, La Merced, Fundo La Genova, AECID A/013484/07, 21.VI.2008.
Female (Fig. 4 D). Fore wing length about 8 mm. Head with occipital carina absent; posterior ocellus separated from eye by about 1.5 times its diameter; mandibles stout, lower tooth clearly longer than upper one; clypeus (Fig. 2 F) with central part concave, centrally with a small apical tubercle; lower face about 1.1 times as broad as medially long, polished, with sparse yellowish setae; antenna slender with about 32 flagellar segments; gena polished with sparse setae. Mesosoma with epomia diverging from anterior margin of pronotum; mesoscutum with central lobe not overhanging pronotum, transverse rugae short, with fairly sparse, short pubescence; mesopleuron polished, with sparse, long setiferous punctures; subalar prominence strongly inflated; epicnemial carina ventrally reaching above level of lower corner of pronotum; hind coxa in profile about 2.2 times as wide as deep; fore wing with cu-a slightly distal to Rs&M; first subdiscal cell broadened distally, its width near outer end about 1.8 times its basal width; abscissa of M between 2rs-m and 2m-cu about 0.4 times as long 2rs-m, Rs weakly and evenly bowed; propodeum short, highly polished, with few setae and with no trace of median longitudinal depression; submetapleural carina sharp throughout. Metasoma with tergite I about 2.0 times as long as posteriorly broad, dorsally smooth and highly polished; tergite II about 1.0 times as long as posteriorly broad, smooth and highly polished, tergites III+ with fine short dense pubescence; ovipositor projecting beyond apex of metasoma by about 4.5 times length of hind tibia.
Coloration. A primarily yellow species, with following areas black: interocellar area and dorsal transverse band from eye to eye, adjacent area to occipital carina, small line from pronotum going down to propleura, anterior and posterior margins of mesopleura and propodeum, scutoscutellar groove and lower part of metanotum; narrow apical bands on tergites III–VII. Flagellum brownish, ovipositor sheath brownish. Wings yellowish, fore wing with a small weak dark patch apically; pterostigma brownish.
Male. Similar to female (male described by Porter (1978)).
Diagnosis. This species can be distinguished from all other Neotropical Epirhyssa by the combination of the following characters: 1) occipital carina absent; 2) tergite I highly polished with very few setae; 3) yellowish annulus over antennal segments 7–9; and 4) fore wing yellowish, weakly infumate. Epirhyssa wisei is closely related to E. isthmia Porter. However, the less elongate body, the lack of a strong apical black band on the fore wing, and the shorter yellow annulus on the antenna differentiate E. wisei.
Notes. The species was originally described based on a single male specimen, so we provide a full description of the female. It has only been found in the Peruvian Amazonia, close to the tropical Andes.
Distribution. Peru.
