The earliest amber-recorded type cockroach family was aposematic (Blattaria: Blattidae)

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

“…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. Šmídová andLei (2017) admits that none of the characters reported for this species, other than the coloration, is indicative of Neostylopyga, Blattinae, or Blattidae.…”

“…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. Šmídová andLei (2017) admits that none of the characters reported for this species, other than the coloration, is indicative of Neostylopyga, Blattinae, or Blattidae. For these reasons and others (small body size may be indicative of another taxonomic assignment, slightly similar color patterns are seen in other Blattidae and some Pseudophyllodromiinae) we consider the evidence placing this species in the Blattinae too weakly justified for use as a fossil calibration.…”

“…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).…”
