Mnioes qanchis sp. nov.

( Figs 6 , 9C )

Diagnosis. Mnioes qanchis sp. nov. can be distinguished from its female congeners by the following combination of traits: face evenly black, flagellomeres 8–20 entirely light yellow, tegula black, mesoscutum black, wings softly infuscate, and ovipositor sheath 2.5× as long as metathoracic tibia.

Material examined. Holotype: ♀, “ PERÚ: MD. Reserva Comunal Amarakaeri 71º07’15.4”W / 12º53’11.5”S, 1044m 09.ix.2010 Malaise M. Vilchez ” ( MUSM).

Description of female holotype. Fore wing length 8.3 mm.

Head: Face granulate-punctate and weakly polished, 0.7× as long as wide; clypeus dorsal half granulate-punctate, ventral half granulate and with scattered punctures, 1.8× 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 44 flagellomeres, ratio of length from second to fourth flagellomeres: 3.0:2.8:2.7, subapical flagellomere 1.1× as long as centrally broad.

Mesosoma : Granulate-punctate and weakly polished; notaulus vestigial, weakly impressed anteriorly; subalar prominence low and 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 two bullae, with abscissa and with a stub on spurious vein; 2rs-m 2.6× as long as abscissa of M between 2rs-m and 2m-cu. Hind wing with length of abscissa of Cu1 between Cu1 and 1A 0.3× as long as length of vein Cu1 between M and Cu1.

Metasoma: Metasomal tergites granulate, matte; tergite I 1.9× as long as posteriorly wide; tergite II 1.1× as long as posteriorly wide; ovipositor sheath 2.5× as long as metathoracic tibia.

Colour: Head black, mandible distally and palpi dark brown, ventral half of clypeus and orbit (between middle of frons and median ocellus) off- white; antenna black with flagellomeres 8–20 entirely light yellow. Mesosoma black. Prothoracic leg with coxa and trochanter black, trochantellus and femur reddish-brown, tibia and basitarsus yellow, tarsomeres 2–4 light brown. Mesothoracic leg with coxa, trochanter, and trochantellus black; femur brown; tibia and tarsus ventrally yellow; tarsus dorsally light brown. Metathoracic leg with coxa, trochanter, trochantellus, and femur black; tibia and tarsus yellow. Wings softly infuscate. Metasomal tergites predominantly reddish brown, tergite I black with anterior margin reddish brown, tergite II with two dark brown spots medially. Ovipositor sheath black, distal end brownish.

Male. Unknown.

Distribution. Madre de Dios ( Fig. 9C ).

Etymology. The specific epithet qanchis means “seven” in Quechua. It is treated as a masculine noun in ap- position.
