“…The number of such basal branches varies among Blattodea. Morphologies comparable to that observed in P. enigmaticus (namely, very numerous basal branches) occur in some Blattellinae (family Ectobiidae -probably a paraphyletic assemblage; see, among others, Klass & Meier 2006, Djernaes et al 2012, Legendre et al 2015 and Blaberidae (see, e.g., Fig. 2B).…”

“…We corroborate previous studies [6,18] in showing that the reduction of the median ocellus is an apomorphy of Blattodea (electronic supplementary material S3 and table S12). This challenges the placement of some purported crown-group fossils with three ocelli [7].…”

Phylogenetic relationships among subgroups of cockroaches and termites are still matters of debate. Their divergence times and major phenotypic transitions during evolution are also not yet settled. We addressed these points by combining the first nuclear phylogenomic study of termites and cockroaches with a thorough approach to divergence time analysis, identification of endosymbionts, and reconstruction of ancestral morphological traits and behaviour. Analyses of the phylogenetic relationships within Blattodea robustly confirm previously uncertain hypotheses such as the sister-group relationship between Blaberoidea and remaining Blattodea, and Lamproblatta being the closest relative to the social and wood-feeding Cryptocercus and termites. Consequently, we propose new names for various clades in Blattodea: Cryptocercus þ termites ¼ Tutricablattae; Lamproblattidae þ Tutricablattae ¼ Kittrickea; and Blattoidea þ Corydioidea ¼ Solumblattodea. Our inferred divergence times

“…The node uniting clevelandellids occurring in blaberiid and blattid cockroaches, was assigned a lower bound of 61 Ma and an upper bound of 407 Ma. The minimum calibration date was based on the oldest known, blaberiid cockroach Gyna obesa (Evangelista et al 2017) and the upper bound on the earliest insect fossils (Bourguignon et al 2018). The node uniting clevelandellids from anurans, was assigned a lower bound of 65 Ma and an upper bound of 275 Ma.…”

Members of the class Armophorea occur in microaerophilic and anaerobic habitats, including the digestive tract of invertebrates and vertebrates. Phylogenetic kinships of metopid and clevelandellid armophoreans conflict with traditional morphology-based classifications. To reconcile their relationships and understand their morphological evolution and diversification, we utilized the molecular clock theory as well as information contained in the estimated time trees and morphology of extant taxa. The radiation of the last common ancestor of metopids and clevelandellids very likely occurred during the Paleozoic and crown diversification of the endosymbiotic clevelandellids dates back to the Mesozoic. According to diversification analyses, endosymbiotic clevelandellids have higher net diversification rates than predominantly free-living metopids. Their cladogenic success was very likely associated with sharply isolated ecological niches constituted by their hosts. Conflicts between traditional classifications and molecular phylogenies of metopids and clevelandellids very likely come from processes, leading to further diversification without extinction of ancestral lineages as well as from morphological plesiomorphies incorrectly classified as apomorphies. Our study thus suggests that diversification processes and reconstruction of ancestral morphologies improve the understanding of paraphyly which occurs in groups of organisms with an apparently long evolutionary history and when speciation prevails over extinction.
