Tanzawana flavomaculata (Hymenoptera, Ichneumonidae, Ctenopelmatinae), a new genus and species of parasitoid of Fagineura crenativora (Tenthredinidae, Nematinae), a serious pest of beech tree

Abstract

We describe a new genus, and a new species, of parasitoid--Tanzawana flavomaculata Watanabe & Kasparyan (Hymenoptera: Ichneumonidae: Ctenopelmatinae)--based on material collected in Honshu, Japan. As T. flavomaculata is found on Fagineura crenativora Vikberg & Zinovjev, 2000 (Hymenoptera: Tenthredinidae), a serious pest of beech tree, this parasitoid is an important natural enemy of F. crenativora that can be used for the biological control of this pest.

Species richness, abundance and diversity of ichneumonid wasps in Japanese beech forests impacted by sika deer and sawfly herbivory

“…1) (Taniwaki & Watanabe 2012; Watanabe & Taniwaki 2018), Ctenopelmatinae ( Tanzawana flavomaculata ) (Watanabe et al . 2015) and Tryphoninae ( Cteniscus fagineurae , Eridolius tanzawanus , Exyston elongatus ) (Watanabe et al . 2018).…”

“…In addition, the faunal make‐up of ichneumonid wasps, especially parasitizing the beech sawfly, has been well studied in the Tanzawa Mountains (Taniwaki & Watanabe 2012; Watanabe et al . 2015, 2018; Watanabe & Taniwaki 2018). Although many species of ichneumonid wasps are recorded from Kanagawa Prefecture, including the Tanzawa Mountains (Nagase & Watanabe 2018), no study has investigated the community structure of ichneumonid wasps.…”

Revision of the tryphonine parasitoids (Hymenoptera: Ichneumonidae) of a beech sawfly, Fagineura crenativora Vikberg & Zinovjev (Hymenoptera: Tenthredinidae: Nematinae)

“…Watanabe et al . () described the ctenopelmatine species as a new genus and species, Tanzawana flavomaculata Watanabe & Kasparyan, 2015, whereas the other species remain unidentified.…”
