Abstract
During a DNA barcoding campaign of leaf-mining Gracillariidae from the Asian part of Russia, a new species of Phyllonorycter Hübner, feeding on the Siberian pea shrub, Caraganaarborescens Lam. (Fabaceae) was discovered in Siberia. Here, this taxon is described as Phyllonorycterivanisp. n. Among Fabaceae-feeding Phyllonorycter, so far only P.caraganella (Ermolaev) has been known to develop on Caragana. Phyllonorycterivani and P.caraganella show a large divergence in morphology (external and male genitalia) and barcode region of the mtDNA-COI gene (8.6%). They feed on different host plants species and have different ranges in Russia. We show that DNA barcode data weakly supports the Fabaceae-feeding species groups. In addition, we show that morphologically (strongly) and genetically (weakly), P.ivani has affinity to the haasi species group, a West Palearctic group with asymmetrical male genitalia.
Highlights
Siberia represents approximately 9% of Earth’s land surface, and its vast boreal forests contain a diverse insect fauna with Lepidoptera being well represented, accounting over 5000 species (Sinev 2008)
We investigate whether DNA barcodes support the different Fabaceaefeeding Phyllonorycter species groups that have been based on the morphology of male genitalia
P. ivani is significantly different from P. caraganella by the asymmetrical valvae
Summary
Siberia represents approximately 9% of Earth’s land surface, and its vast boreal forests contain a diverse insect fauna with Lepidoptera being well represented, accounting over 5000 species (Sinev 2008). Among Lepidoptera, micromoths show high species richness with some species being agricultural and forest pests and invaders (Kuznetzov 1999; Kirichenko et al 2018a) Despite their ecological and economic importance, micromoths remain largely understudied (Sinev 2008; Lees et al 2013; Lopez-Vaamonde et al 2018). In Siberia, leaf-mining micromoths and the economically important family Gracillariidae have been the focus of recent studies, using DNA barcoding as a main tool to discover new species and host plant associations (Kirichenko et al 2016, 2017, 2018b, 2018c, 2019; Akulov et al 2018; Knyazev et al 2018). Of these 57 species, 39 (i.e., 68%) are known to be strictly monophagous, feeding on a single legume species Of these 57 species, 39 (i.e., 68%) are known to be strictly monophagous, feeding on a single legume species (Suppl. material 1: Table S1)
