Taxonomic catalogue of the earwigs (Insecta: Dermaptera) of Mexico, with two new nomina dubia

A comprehensive and annotated catalogue of the earwigs (Insecta: Dermaptera) that inhabit Mexico was compiled. Six families were recorded: Anisolabididae with 4 genera and 5 species; Forficulidae with 9 genera and 23 species; Haplodiplatyidae with 1 genus and 3 species; Labiduridae with 1 genus and 1 species; Pygidicranidae with 1 genus and 1 species; and Spongiphoridae with 7 genera and 21 species; totaling 23 genera and 54 species.

Additionally, 5 fossil species are listed, in 3 current genera and 1 fossil genus, belonging to the families Haplodiplatyidae (1 species) and Spongiphoridae (4 species). Finally, 14 records were considered dubious for the country. The states with the most species of earwigs recorded are Veracruz with 30 species, Morelos with 10 species and Guerrero with 9 species; no records are known from Campeche and Tlaxcala.

The original descriptions of Ancistrogaster burri Kirby, 1903 and Paracosmia gulosa (Scudder 1876) (Forficulidae) were revisited. Given the lack of type material and that the descriptions were deemed too vague to accurately identify them, these taxa are hereby relegated as nomina dubia.
