New aposematic and presumably repellent bark cockroach from Lebanese amber

Fossil calibrations for the cockroach phylogeny (Insecta, Dictyoptera, Blattodea), comments on the use of wings for their identification, and a redescription of the oldest Bla

“…Scudder 12 (1890) gives no evidence for its placement, and his illustration of the fossil does not provide any diagnostic characters. Šmídová and Lei (2017) and Sendi and Azar (2017) describe species of the genus Balatronis Šmídová and Lei, 2017, of the family Blattidae from Lebanese amber. However, Balatronis libanensis Sendi and Azar, 2017, is likely in a different family due to the presence of a central ocellus (not seen in any extant cockroaches).…”

Balatronis cretacea Šmídová and Lei, 2017, the type species, is only supported in the family Blattidae by its similar coloration to the extant genus Neostylopyga Shelford, 1911.…”

“…It is manifested both in morphological and molecular analysis as a “long branch”, the most basal, earliest derived group among extant standard cockroaches according to the molecular analyses (Klass & Meier, 2006; Legendre et al, 2015). In contrast, the fossil record reveals earlier branched Ectobiidae and Blattidae (Sendi & Azar, 2017) and Anaplecta is considered more recent.…”
