| dc.description.abstract | The systematic status of the genus Athalia and related genera is a perennial controversy
in sawfly taxonomy. Several authors have hypothesized that the placement of Athalia within the
Tenthredinidae is artificial, but no studies have focused on this topic. If the hypothesis that Athalia
does not belong to Tenthredinidae can be supported, the taxonomic framework of Tenthredinoidea
needs revision. We present a comprehensive phylogenomic study of Tenthredinoidae, focusing on the
positions of Athalia and related genera by sampling 80 representatives mainly of the Tenthredinoidea,
including Heptamelinae and Blasticotomidae. Our phylogenetic reconstructions based on nuclear
genes and mitochondrial (mt) sequences support Athalia and related genera as a distinct clade sister to
Tenthredinidae + (Cimbicidae + Diprionidae). A comparison of symphytan mitochondrial genomes
reveals an innovative gene rearrangement pattern in Athaliidae, in which Dentathalia demonstrates a
more ancestral pattern than Athalia and Hypsathalia. The lineage specificity of mt rRNA secondary
structures also provides sufficient support to consider Athaliidae as a separate family. In summary,
the phylogeny and genomic structural changes unanimously support the taxonomic treatment of
Athaliidae as a family and the re-establishment of Dentathalia as a valid genus. | tr |
