Here we provide the first thorough assessment of the fossil calibrations for divergence time estimation of cockroaches. [] Key Method Through a review of published fossil descriptions, we evaluate oldest fossils for various nodes in crown Blattodea in accordance with recently proposed best practices. Since most descriptions of fossil cockroaches rely heavily on wing and tegminal venation, we also provide a critical assessment of Rehn (1951), which is the most extensive work on these characters. We find that…

Phylogeny and age of cockroaches: a reanalysis of mitogenomes with selective fossil calibrations

TLDR
This study emphasizes the completeness of data, the reliability of genes (judged via alignment ambiguity and substitution saturation), and the justification for fossil calibrations, and shows that appropriate Fossil calibrations are rarer than considered in previous studies.
Earliest record of fossil insect oothecae confirms the presence of crown‐dictyopteran taxa in the Late Triassic
TLDR
Two new oothecae ichnospecies found in a Carnian deposit from Argentina are reported, moving the origin of this specialized reproductive strategy back by 100 million years and providing direct fossil evidence that can inform future research on the origins and timing of diversification of the Dictyoptera.
Prayers for fossil mantis unfulfilled: Prochaeradodis enigmaticus Piton, 1940 is a cockroach (Blattodea)
TLDR
Three independent morphological character states are recognized supporting an unequivocal placement of the fossil within Blattodea (cockroaches and termites) and this new placement discounts the use of this fossil as a Mantodea tree calibration point.
An integrative phylogenomic approach illuminates the evolutionary history of cockroaches and termites (Blattodea)
TLDR
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 shows that most subgroups of Blattodea evolved in the Cretaceous.
Reconstructing the phylogeny of Blattodea: robust support for interfamilial relationships and major clades
TLDR
Preliminary phylogenetic relationships among cockroaches based on five genes, combined with data from a recent study that examined these same genes from 49 species, resulted in significantly higher levels of support for a number of previously recognized groupings.
Nocticolid cockroaches are the only known dinosaur age cave survivors
Digging deep: a revised phylogeny of Australian burrowing cockroaches (Blaberidae: Panesthiinae, Geoscapheinae) confirms extensive nonmonophyly and provides insights into biogeography and evolution of burrowing
TLDR
No support is found for retaining Geoscapheinae as a discrete taxonomic grouping among Australian members of these two subfamilies using whole mitochondrial genomes paired with nuclear ribosomal markers and highly conserved genes from the bacterial endosymbiont Blattabacterium.
Maternal care by Early Cretaceous cockroaches
TLDR
It is inferred that the cockroach reproductive mode using the complete oothecate structure occurred during or before the mid Early Cretaceous, and a new life-history trait providing maternal protection and care may have been a key factor in the subsequent evolutionary diversification and ecological expansion of modern cockroach lineages.

Phylogeny of cockroaches (Insecta, Dictyoptera, Blattodea), with placement of aberrant taxa and exploration of out‐group sampling
TLDR
The phylogeny of cockroaches is addressed using DNA sequence data from a broad taxon sample of Dictyoptera and other non‐endopterygotan insect orders, and Lamproblattidae was recovered as sister to Polyphagidae, consistent with the traditional placement.
Phylogeny of Dictyoptera: Dating the Origin of Cockroaches, Praying Mantises and Termites with Molecular Data and Controlled Fossil Evidence
TLDR
The authors' datings suggest that crown-Dictyoptera—and stem-mantises—would date back to the Late Carboniferous, a result compatible with the oldest putative fossil of stem-dictyopteran suborders, and suggests a scenario of replacement in carnivory among polyneopterous insects.
Albian cockroaches (Insecta, Blattida) from French amber of Archingeay
TLDR
Phase-contrast X-ray synchrotron imaging, a technique recently developed for analysing amber inclusions, is used here for the first time to reconstruct very detailed views of two cockroach specimens fossilised in a piece of opaque amber.
The Blattodea s.s. (Insecta, Dictyoptera) of the Guiana Shield
TLDR
A checklist of cockroach species known from areas within the Guiana Shield based on literature records and new field collection shows particularly low richness in Guianan Venezuela, Roraima and Amapa Brazil, but this is likely an artifact due to under–sampling.
Evidence for Carboniferous origin of the order Mantodea (Insecta: Dictyoptera) gained from forewing morphology
TLDR
The homology statement implies that the total-group Mantodea arose as soon as the Late Carboniferous, i.e. about 175 million years earlier than previously estimated, suggesting a survivorship of several main Pterygota lineages at the end-Permian extinction event higher than previously expected.
Morphological evidence on blattarian phylogeny: “phylogenetic histories and stories” (Insecta, Dictyoptera)
TLDR
It is thus another demonstration that extensive and detailed morphological investigations and structural comparisons between taxa are essential for morphology-based phylogenetic work, in particular if complex and diverse organs (such as the dictyopteran phallomeres) are used.
Taxonomic diversity of cockroach assemblages (Blattaria, Insecta) of the Aptian Crato Formation (Cretaceous, NE Brazil)
Abstract A comprehensive revision of 981 specimens of fossil cockroaches from the Lower Cretaceous laminated limestones of the Crato Formation of Northeast Brazil shows that they belong to eleven
New predatory cockroaches (Insecta: Blattaria: Manipulatoridae fam.n.) from the Upper Cretaceous Myanmar amber
TLDR
A new extinct lineage Manipulatoridae (new family) of cockroaches from the Upper Cretaceous (Cenomanian) amber of Myanmar is described, which represents the first (of a total of 29 known worldwide) cockroach family reported exclusively from the Myanmar amber.
Testing decreasing variabililty of cockroach forewings through time using four Recent species: Blattella germanica, Polyphaga aegyptiaca, Shelfordella lateralis and Blaberus craniifer, with implications for the study of fossil cockroach forewings
TLDR
The new results indicate that Recent species can be more variable than fossil species and therefore do not support the theory that there is decreasing variability in the forewings of cockroaches through time.
New Blattarians and a Review of Dictyopteran Assemblages from the Lower Cretaceous of Mongolia
TLDR
Assemblages from Eastern Erdenyi-Ula, Khurilt, Kholbotu-Gol, and Shar-Tologoy are composed of species already known from the richest Lower Cretaceous locality Bon Tsagaan, but species representation in the various assemblages differs considerably.
