Alvarado, Mabel, 2020, Ten new species of parasitoid wasps Mnioes Townes, 1946 (Hymenoptera: Ichneumonidae: Banchinae) described from Peru, Zootaxa 4743 (2), pp. 181-199 : 189-190

Mnioes kinsa sp. nov.

( Figs 4C , 9B )

Diagnosis. Mnioes kinsa sp. nov. can be distinguished from its female congeners by the following combination of traits: frontal and facial orbit white, tegula light yellow, mesoscutum with a light yellow spot at center, metasoma red, flagellomeres 7–20 entirely white, ovipositor sheath 2.1× as long as metathoracic tibia. It resembles to M. nalbes Ugalde-Gómez and Gauld, 2002 as both have females with gena black, mesoscutum black with a small central white mark, metasoma predominantly reddish, and propodeum black with posterolateral white marks; they differ in the length of the ovipositor sheaths 2.1× as long as metathoracic tibia in M. kinsa sp. nov. (vs. 2.9–3.1×) and meso- and metathoracic tibia off-yellow (vs. basally reddish and distally infuscate).

Material examined: Holotype: ♀, “ PERÚ: PA. Oxapampa , PN Yanachaga-Chemillen, Puesto Huampal 10º10’57”S / 75º34’25.6”W 1001m 30.iv–02.v.2010 C. Carranza Leg ” ( MUSM). Left leg removed for molecular work [DNA-Ichn 00020], and right tarsus missing.

Description of female holotype. Fore wing length 8.6 mm.

Head: Face granulate-punctate and weakly polished, 0.7× as long as wide; clypeus dorsal half granulate, ventral half granulate-punctate, 1.9× as wide as long; malar space 0.6× as long as basal mandibular width; lateral ocellus separated from compound eye by about 1.2× maximum ocellar diameter; distance between ocelli 1.1× maximum ocellar diameter; scape with truncated sections V-shaped; with 45 flagellomeres, ratio of length from second to fourth flagellomeres: 2.9:2.6:2.6, subapical flagellomere 1.8× 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, weakly folded in homologous position to lateral longitudinal carina next to spiracle; pleural carina present; with a weak vestige of posterior transverse carina present, except laterally. Fore wing with vein 1m-cu without a ramellus; vein 2m-cu weakly sinuate, with a two bullae, with abscissa and without 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 0.3× 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 1.1× as long as posteriorly wide; ovipositor sheath 2.1× as long as metathoracic tibia.

Colour: Head predominantly light yellow, but face with a median vertical mark, upper half of clypeus, frons centrally, vertex, and gena black; antenna predominantly black, scape ventrally light yellow, and flagellomere 6 ventrally and flagellomeres 7–20 entirely white. Mesosoma predominantly black, but light yellow on anterior margin and postero-dorsal corner of pronotum, mesoscutellum, postscutellum, a spot at center of mesoscutum, a spot postero-ventrally of mesopleuron, subalar prominence, tegula, humeral plate, dorsal most section of mesepisternum, dorso-centrally of metapleuron, propodeum laterally (between spiracle and posterior transverse carina) and midsection of posterior transverse carina. Legs reddish with prothoracic coxa lateroventrally (dorsally brownish) and mesothoracic coxa lateroventrally (basally) light yellow, mesothoracic tarsus brown, meso- and metathoracic tibia off-yellow. Wings hyaline. Metasomal tergites predominantly reddish, anterior third of length of tergite I and posterior margin of tergite II yellowish, posterior margin of tergite I off-white. Ovipositor sheath black.

Male. Unknown.

Distribution. This species was collected in a cloud forest in Yanachaga–Chemillén National Park, Pasco ( Fig. 9B ).

Etymology. The specific epithet kinsa means “three” in Quechua. It is treated as a masculine noun in apposi- tion.
