Mnioes pusaq sp. nov.

( Figs 5C, 9B)

Diagnosis. Mnioes pusaq sp. nov. can be distinguished from its female congeners by the following combination of traits: face black, flagellomeres 8–14 dorsally white, mesoscutum black, tegula brownish, metasoma predominantly red, wings softly infuscate but centrally hyaline, and ovipositor sheath 2.2× as long as metathoracic tibia,

Material examined. Holotype: ♀, “ PERU: CA. Monteseco , ~ 1232m. 6°51’34.5”S / 79°6’41.5”W. 17.v.2010 J. Grados leg.” ( MUSM).

Description of female holotype. Fore wing length 7.1 mm.

Head: Face granulate-punctate and weakly polished, 0.7× as long as wide; clypeus dorsal half granulate-punctate, ventral half granulate, 2.1× as wide as long; malar space 0.8× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.1× maximum ocellar diameter; distance between ocelli 1.1× maximum ocellar diameter; scape with truncated section V-shaped, with 41 flagellomeres, ratio of length from second to fourth flagellomeres: 3.1:2.8:2.6, subapical flagellomere 1.2× as long as centrally broad.

Mesosoma : Granulate-punctate and weakly polished; notaulus vestigial, weakly impressed anteriorly; subalar prominence low and weakly rounded. Propodeum granulate-punctate; evenly declivous from anterior margin; pleural carina present; with a weak vestige of posterior transverse carina centrally. Fore wing with vein 1m-cu with a ramellus; vein 2m-cu weakly sinuate, with a two bullae, with abscissa and with a stub on spurious vein; 2rs-m 3.2× as long as abscissa of M between 2rs-m and 2m-cu. Hind wing with length of abscissa of Cu1 between Cu1 and 1A 0.1× as long as length of vein Cu1 between M and Cu1.

Metasoma: Metasomal tergites granulate, matte; tergite I 2.3× as long as posteriorly wide; tergite II 1.2× as long as posteriorly wide; ovipositor sheath 2.2× as long as metathoracic tibia.

Colour: Head predominantly black; lower half of clypeus, middle of mandibles, palpi and frontal orbit (between antennal socket and after median ocellus) off-white; antenna predominantly black, scape ventrally brownish, flagellomeres 8–14 dorsally white. Mesosoma ( Fig. 5C) predominantly black, but light yellow on anterior margin (dorsally) of pronotum, mesoscutellum, subalar prominence, dorsal most section of mesepisternum, and dorsocentrally of metapleuron (surrounded by a reddish-brown coloration), and brownish on tegula, humeral plate, and postscutellum. Legs predominantly reddish, prothoracic and mesothoracic tarsomeres light brown; mesothoracic tibia apically and tarsus brown but apical half of tarsomere 1 and tarsomere 2 off-white. Wings softly infuscate, centrally hyaline. Metasomal tergites ( Fig. 5C) predominantly red, posterior margin of tergites I–II yellowish. Ovipositor sheath black.

Male. Unknown.

Distribution. Cajamarca ( Fig. 9B), from the Andes western slopes.

Etymology. The specific epithet pusaq means “eight” in Quechua. It is treated as a masculine noun in apposition.
