Revision of the Swedish species of Neoxorides Clément, 1938 (Ichneumonidae: Poemeniinae) with the description of a new species and an illustrated key to species

Abstract

<jats:p>Neoxorides Clément, 1938 is a small genus of ichneumonid wasps that develop on wood-boring beetles. We here revise the Western Palaearctic species of the genus, with a special focus on Sweden. A new species, N. striatus Johansson sp. nov. is described. Neoxorides opacus (Kokujev, 1903) stat. rev. is excluded from the synonymy with N. nitens (Gravenhorst, 1829) and reinstated as a valid species. The species is redescribed from European material. Neoxorides kissi (Ulbricht, 1911) is confirmed as a junior synonym of N. opacus. A neotype for N. opacus is designated. New characters to distinguish N. varipes (Holmgren, 1860), N. collaris (Gravenhorst, 1829) and N. montanus Oehlke, 1966 are presented. Almost all of the species treated are supported by DNA-barcoding. An illustrated key to the species occurring in the Western Palaearctic is provided, a prerequisite for making the genus accessible for future ecological and conservation studies.</jats:p>

Open access in a taxonomic sense: a morphological and molecular guide to Western Palaearctic Dusona (Hymenoptera, Ichneumonidae)

“…Furthermore, there might be habitat types that have not been covered extensively by SMTP (Johansson 2020), hence additional sampling might be necessary to complete the faunistic records for this genus. This result lends support to other studies that showed major knowledge gaps for parasitoid wasps and Diptera, even in the faunistic record of well-studied countries such as Sweden (Johansson and Cederberg 2019;Johansson 2020;Johansson and Klopfstein 2020;Riedel 2020;Ronquist et al 2020). Several of the newly recorded species were restricted to southern and coastal areas (Fig.…”

“…The PCRs for CAD were run at an annealing temperature of 52 °C. Two additional internal primers for degenerated COI sequences were used; forward FA336 and reverse RA435 (Johansson and Klopfstein 2020), these primers were combined with LCO/HCO and run on an annealing temperature at 50 °C. The quality of the PCR products was then checked on a 2% agarose electrophoresis gel and they were sent for cleanup and sequencing to Macrogen Europe in the Netherlands.…”

“…se/). The faunistic provinces included were Lycksele Lappmark, Norrbotten, Pite Lappmark, Västerbotten, Ångermanland, and Åsele Lappmark (Johansson and Klopfstein 2020). Based on herbarium records, 79 species representing 25 genera had been collected in these six northernmost provinces.…”

New Records of Poemeniinae and Xoridinae (Hymenoptera, Ichneumonidae) from Ukraine and Poland, with Corrections to the Ukrainian Checklist

“…Poemeniinae and Xoridinae are relatively small subfamilies of the Darwin wasps (Hymenoptera, Ichneumonidae) represented in Europe by 13 and 50 species, respectively (Kasparyan, 1981;Yu et al, 2016;Johansson & Klopfstein, 2020;Johansson, 2022;Johansson et al, 2022). Th e representatives of both subfamilies are recorded mainly as idiobiont ectoparasitoids of saproxylic coleopterans and hymenopterans (Yu et al, 2016).…”

“…Poemeniines and xoridines are among the best studied ichneumonid groups in both Poland and Ukraine, with 8 and 31 species (Hilszczanski, 2002;Bogdanowicz et al, 2007), and 11 and 30 species (Varga, 2015 a, b;Johansson & Klopfstein, 2020), respectively.…”
