Mnioes pisqa sp. nov.

( Figs 5 A–B, 9B)

Diagnosis. Mnioes pisqa sp. nov. can be distinguished from its female congeners by the following combination of traits: frontal orbit yellowish, flagellomeres 5–22 entirely yellow, ovipositor sheath 2.5× as long as metathoracic tibia.

Material examined. Holotype: ♀, “ PERU: CU, La Convención , Echarate, CC. Otsanampiato 12º39’39.55”S / 73º09’24.92”W 1654m. 15.ix.2010. Light, M. Alvarado y J. Peralta ” . Paratype. 1♀, same data as holotype ( MUSM) .

Description of female holotype. Fore wing length 7.6 mm.

Head: Face granulate-punctate and weakly polished, 0.7× as long as wide; clypeus granulate-punctate, 1.9× as wide as long; malar space 0.9× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.1× maximum ocellar diameter; distance between ocelli 1.0× maximum ocellar diameter; scape with truncated section V-shaped ( Fig. 5B ), with 45 flagellomeres, ratio of length from second to fourth flagellomeres: 2.7:2.5:2.5, subapical flagellomere 0.9× 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; declivous from anterior margin, centrally between anterior margin and posterior transverse carinae with a median longitudinal concavity, weakly folded in homologous position to lateral longitudinal carina only next to spiracle; pleural carina present; posterior transverse carina present. 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 3.1× as long as abscissa of M between 2rs-m and 2m-cu. Hind wing with length of abscissa of Cu1 between Cu1 and 1A 0.4× as long as length of vein Cu1 between M and Cu1.

Metasoma: Metasomal tergites granulate, matte; tergite I 2.0× as long as posteriorly wide; tergite II 1.3× as long as posteriorly wide; ovipositor sheath 2.5× as long as metathoracic tibia.

Colour: Head black, ventral half of clypeus off-white, palpi orange, orbit (between antennal socket and median ocellus) yellow; antenna black with apical half of flagellomere 3, basal half of flagellomere 4, and flagellomere 2–3 brown, apical half of flagellomere 4, 5–22 (entirely) yellow. Mesosoma ( Fig. 5A ) black, subalar prominence brownish black.Legs orange, prothoracic leg with coxa basally brownish, tarsomere 3–5 of prothoracic and mesothoracic leg light brown. Wings softly infuscate. Metasomal tergites orange; tergite I centrally brownish; ovipositor sheath dark brown.

Variation of female paratype. Fore wing length 8.0 mm. It differs from the holotype in the following features: clypeus 1.8× as wide as long; lateral ocellus separated from compound eye by about 1.0× maximum ocellar diameter; ratio of length from second to fourth flagellomeres: 2.7:2.3:2.3; fore wing with vein 1m-cu without a ramellus, vein 2m-cu without a stub on spurious vein, 2rs-m 3.0× as long as abscissa of M between 2rs-m and 2m-cu; tergite I 2.1× as long as posteriorly wide.

Male. Unknown.

Distribution. The species was collected in Cuzco department ( Fig. 9B ), using light traps.

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