Mnioes huk sp. nov.

( Figs 2 View FIGURE 2 , 9A View FIGURE 9 )

Diagnosis. Mnioes huk sp. nov. can be distinguished from its female congeners by the following combination of traits: facial orbit light yellow, flagellomeres 8–15 entirely light yellow, mesoscutum and tegula black, wings evenly infuscate, and ovipositor sheath 2.8× as long as metatibia.

Material examined: Holotype: ♀ “ PERÚ: PA. Villa Rica, Z.A. del Bosque San Matías San Carlos 75º12’37”W / 10º38’44”S 1596m 06-10.viii.2012 FIT P. Sánchez & E. Rázuri ” GoogleMaps . Paratype: 1♀, similar to holotype ( MUSM) .

Description of female holotype. Fore wing length 8.8 mm.

Head: Face ( Figs 2 View FIGURE 2 B–C) granulate-punctate and weakly polished, 0.8× as long as wide; clypeus granulate with scatteed punctures, 2.0× as wide as long; malar space 0.7× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.1× maximum ocellar diameter; distance between ocelli 0.9× maximum ocellar diameter; scape with truncated section V-shaped, with 48 flagellomeres, ratio of length from second to fourth flagellomeres: 3.2:2.8:2.7, subapical flagellomere 1.0× as long as centrally broad.

Mesosoma : Granulate-punctate and weakly polished; notaulus vestigial, weakly impressed anteriorly; subalar prominence low and weakly rounded. Propodeum ( Fig. 2D View FIGURE 2 ) 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; pleural carina present; posterior transverse carina present, except laterally. 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 3.5× as long as abscissa of M between 2rs-m and 2m-cu. Hind wing with length of abscissa of Cu1 between Cu1 and 1A 0.2× as long as length of vein Cu1 between M and Cu1.

Metasoma: Metasomal tergites granulate, matte; tergite I 2.8× as long as posteriorly wide; tergite II 1.2× as long as posteriorly wide; ovipositor sheath 2.8× as long as metathoracic tibia ( Fig. 2A View FIGURE 2 ).

Colour: Head ( Figs 2 View FIGURE 2 B–C) black, face (with a median vertical brown mark), clypeus, mandibles, and orbit (reaching to median ocellus) light yellow, palpi off-white; antenna black with scape ventrally orange, apical third of flagellomere 7 and flagellomeres 8–15 entirely light yellow. Mesosoma predominantly black with anterior margin of pronotum yellowish. Prothoracic and mesothoracic legs orange, tarsomeres 2–5 brown. Metathoracic leg with coxa, trochanter, trochantellus, and basal end of femur orange; femur, tibia, basal quarter of length of basitarsus, and tarsomere 5 black; distal 3/4 of the length of basitarsus and tarsomeres 2–4 white. Wings evenly infuscate. Metasomal tergites predominantly orange, tergite I centrally and tergites II–IV with maculae brownish. Ovipositor sheath dark brown.

Variation of female paratype. Fore wing length 10.7 mm. It differs from the holotype in the following features: ratio of length from second to fourth flagellomeres: 3.3:2.9:2.8; fore wing with vein 2m-cu without a stub on spurious vein, 2rs-m 4.0× as long as abscissa of M between 2rs-m and 2m-cu; tergite I 2.6× as long as posteriorly wide; tergite II 1.3× as long as posteriorly wide; and ovipositor sheath 2.9× as long as metathoracic tibia. Within the coloration: face predominantly brown with facial orbit light yellow, mesosoma evenly black; prothoracic and mesothoracic coxae and mesothoracic femur brownish; metathoracic coxa, trochanter, trochantellus, and femur black; metasomal tergites predominantly orange, tergite I brown with posterior margin orange.

Male. Unknown.

Distribution. This species is was collected in a primary cloud forest, in the buffer zone of San Matías–San Carlos Protection Forest, Pasco ( Fig. 9A View FIGURE 9 ).

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