A remarkable new genus and species of Euryproctini (Hymenoptera: Ichneumonidae, Ctenopelmatinae) from Thailand

“…The tribe Euryproctini Thomson, 1883, together with eight other tribes, comprise the subfamily Ctenopelmatinae Förster, 1869 (Hymenoptera, Ichneumonidae), one of the most poorly known groups of Darwin wasps (Gauld 1997). The Ctenopelmatinae are well represented in all major biogeographical regions, occurring from the Arctic to the tropics, and comprising 1616 species in 111 genera, including 265 species and 19 genera of Euryproctini (Reshchikov 2011(Reshchikov , 2016Kasparyan 2016Kasparyan , 2017Kasparyan , 2018Kasparyan , 2020aKasparyan , 2020bKasparyan , 2021aKasparyan , 2021bKasparyan et al 2016;Lima & Kumagai 2016;Yu et al 2016Yu et al , 2018Yu et al , 2020aYu et al , 2020bYu et al , 2021aYu et al , 2021bReshchikov et al 2017aReshchikov et al , 2017bReshchikov et al , 2017cReshchikov et al , 2019Reshchikov & van Achterberg 2018;Khalaim et al 2019;Sun et al 2019Sun et al , 2020Sun et al , 2021aSun et al , 2021bLi et al 2020;Sheng et al 2020Sheng et al , 2022Watanabe 2021;Li & Sun 2022), excluding genera we consider belonging to Metopiinae Förster, 1869 (Bremiella Dalla Torre, 1901(Quicke et al 2009 and Scolomus Townes & Townes, 1950 (Gauld & Wahl 2006;Araujo et al 2018)).…”

A new genus and species of Ctenopelmatinae (Hymenoptera, Ichneumonidae) from China

“…The Ctenopelmatinae are a large subfamily of ichneumonid wasps currently comprising 110 genera and 1617 described species, most of which are koinobiont endoparasitoids of sawflies of the superfamilies Pamphilioidea and Tenthredinoidea (Aubert 2000;Yu et al 2016;Khalaim et al 2019;Kasparyan 2020aKasparyan , b, 2021Sheng et al 2020Sheng et al , 2022Sun et al 2021a, b;Watanabe 2021;Li and Sun 2022). The subfamily is subdivided into nine tribes, eight of which have been reported in China (Townes 1970;Yu et al 2016;Sheng et al 2020).…”
