A new species of Micrurapteryx (Lepidoptera, Gracillariidae) feeding on Thermopsis lanceolata (Fabaceae) in southern Siberia and its hymenopterous parasitoids

Abstract

A new species of leaf-mining moth described here as Micrurapteryx baranchikovi Kirichenko, Akulov & Triberti, sp. nov. was detected in large numbers feeding on Thermopsis lanceolata (Fabaceae) in the Republic of Khakassia (Russia) in 2020. A morphological diagnosis of adults, bionomics and DNA barcoding data of the new species are provided. The developmental stages (larva, pupa, adult), male and female genitalia, as well as the leaf mines and the infestation plot in Khakassia are illustrated; the pest status of the new species in the studied region is discussed. Additionally, parasitism rate was estimated, the parasitoid wasps reared from pupae of the new species were identified (morphologically and genetically) and illustrated . Among them, one ichneumonid, Campoplex sp. aff. borealis (Zetterstedt) and two braconids, Agathis fuscipennis (Zetterstedt) and Illidops subversor (Tobias et Kotenko), are novel records for the Republic of Khakassia. Furthermore, they are all documented as parasitoids of Gracillariidae for the first time. The DNA barcode of A. fuscipennis is newly obtained and can be used as a reference sequence for species identification.
