Phylogenomic approaches have recently helped elucidate various insect relationships, but large-scale comprehensive analyses on relationships within sawflies and woodwasps are still lacking. Here, we infer the long-term biogeographic history of these hymenopteran groups using a large dataset 354 UCE loci collected from 385 species that represent all major lineages. Early Hymenoptera started diversifying during Triassic ∼249 Ma spread over ancient supercontinent Pangaea. We recovered Xyeloidea...

Accurate identification and precise classification of freshwater mussel species that are among the most threatened taxa in world, play a crucial role informing conservation management efforts for these organisms. However, due to variability shell morphology, relying solely on characteristics taxonomy poses significant challenges, thereby impeding effective planning management. The genus Ptychorhynchus Simpson, 1900 is one such group need study. We integrate molecular phylogeny, morphology...

The systematic status of the genus Athalia and related genera is a perennial controversy in sawfly taxonomy. Several authors have hypothesized that placement within Tenthredinidae artificial, but no studies focused on this topic. If hypothesis does not belong to can be supported, taxonomic framework Tenthredinoidea needs revision. We present comprehensive phylogenomic study Tenthredinoidae, focusing positions by sampling 80 representatives mainly Tenthredinoidea, including Heptamelinae...

Abstract Mitogenomes are known for their structural dynamics and the complexity of rearrangement patterns. However, utility in metazoan comparative biology has not been fully exploited. Vertebrate mitogenomes now sufficiently representative to allow development more advanced methods comparing genome architecture. Furthermore, relatively robust phylogeny vertebrates at higher taxonomic ranks allows us infer patterns evolution accordingly. In this study, using amphibians as an example, we...
