Blattoidea are comprised of the major lineages Blattidae, Lamproblattidae, Tryonicidae, Anaplectidae, and Cryptocercidae + Isoptera. Despite a number studies, no consensus exists regarding relationships between these lineages. Additionally, current division Blattidae into Archiblattinae, Blattinae, Macrocercinae Polyzosteriinae needs phylogenetic testing. We present molecular phylogeny recoveri...

Abstract The past diversity of Isoptera is relatively poorly documented. Many early-diverging families are only represented today by relicts their Mesozoic and Cenozoic richness. Therefore, the onset evolutionary history transitions between families, or even subsocial eusocial ways life, remain difficult to decipher require additional fossil occurrences. Here, we report oldest worker/pseudergat...
