Alvarado, Mabel, 2020, Ten new species of parasitoid wasps Mnioes Townes, 1946 (Hymenoptera: Ichneumonidae: Banchinae) described from Peru, Zootaxa 4743 (2), pp. 181-199 : 183-186

Mnioes attenboroughi sp. nov.

( Figs 1 , 9A )

Diagnosis. Mnioes attenboroughi sp. nov. can be distinguished from its female congeners by the following combination of traits: frontal orbit white, tegula black, coxae predominantly red, wings hyaline, ovipositor sheath length 2.3–2.5× as long as metathoracic tibia; while the male can be distinguished due its mesoscutum entirely black and wings hyaline. M. attenboroughi sp. nov. resembles to M. tawa sp. nov. as both have females with mesosoma and metasoma extensively black and wings hyaline; they differ mainly the coloration of the coxae, trochanters and trochantellus predominantly red in M. attenboroughi sp. nov. (vs. predominantly black).

Mesosoma ( Fig. 1B ) predominantly black with anterior margin and postero-dorsal corner of pronotum, prosternum, mesosternum, subalar prominence, tegula, humeral plate, mesoscutellum, lower half of mesopleuron, dorsal most section of mese- pisternum, and a spot dorso-posteriorly of metapleuron white. Prothoracic leg orange, coxa and trochanter white, tarsus light brown. Mesothoracic leg orange, coxa anteriorly white, tarsus brown. Metathoracic leg orange, coxa basal-dorsally white, tibia brown, tarsomeres 1–4 white, and tarsomere 5 black. Wings hyaline. Metasomal tergites predominantly black; anterior and posterior margins of tergites I–III white or off-white; posterior margin of tergite IV white or off-white; tergite I laterally, in some individuals, off-white (rarely also of tergites II–III); posterior margin of tergites IV–VI off-white or black; mid-posterior margin of tergite VII white.

Comments. The specimens from the Albergue Refugio Amazonas were collected by guests at the Refugio Amazonas Lodge, located on the right bank of the Tambopata River (Madre de Dios, Peru), as part of a Citizen Science program, with the mutual collaboration between the MUSM and Rainforest Expeditions. The collections done in the Refugio Amazonas lodge used light, Malaise, and pan traps (daily serviced) from March 2016 to August 2017, and the collections at the Explorer’s Inn were carried out from December 2008 to November 2009 using solely Malaise traps; these collections showed that the species flies throughout the year, except January and February.

Distribution. This species is widely distributed in the Amazon basin ( Fig. 9A ), from sea level to 600m, rarely, between 1000–1200m.

Etymology. The specific epithet attenboroughi honours Sir David Frederick Attenborough; the members of the project “Discovery new species” want to commemorate him for raising awareness about the importance of wildlife conservation and his educational documentaries on wildlife that inspired many biologists, among them the author.
