Pygidicranidae is a family of earwigs in the suborder Neodermaptera. The family currently contains twelve subfamilies and twenty six genera. Eight of the subfamilies are monotypic, each containing a single genus. Of the subfamilies, both Astreptolabidinae and Burmapygiinae are extinct and known solely from fossils found in Burmese amber. Similarly Archaeosoma, Gallinympha, and Geosoma, which have not been placed into any of the subfamilies, are also known only from fossils. Living members of the family are found in Australia, South Africa, North America, and Asia. The monotypic genus Anataelia, described by Ignacio Bolivar in 1899, is found only on the Canary Islands. As with all members of Neodermaptera, pygidicranids do not have any ocelli. The typical pygidicranid bodyplan includes a small, flattened-looking body, which has a dense covering of bristly hairs (setae). The pair of cerci at the end of the abdomen are symmetrical in structure. The head is broad, with the fourth, fifth and sixth antenna segments (antennomeres) that are not transverse. In general Pygidicranids also have equally sized ventral cervical sclerites, and in having the rearmost sclerite separated from, or only touching the center of the prosternum. Cannibalism of young has been observed in at least one species in the family, Challia hongkongensis, in which an adult female was found eating a still-living nymph of the same species. The same species in a different area has been observed possibly eating fruits or seeds, making the species an omnivore.
Forficulidae is a family of earwigs in the order Dermaptera. There are more than 70 genera and 490 described species in Forficulidae.
Ctenisolabis is a genus of earwigs in the subfamily Brachylabidinae.
Euborellia is a genus of earwigs in the subfamily Anisolabidinae. This genus, which has a world-wide distribution, was erected by Malcolm Burr in 1909 and was cited by Srivastava in Part 2 of Fauna of India.
Chelisochidae is a family of earwigs whose members are commonly known as black earwigs. The family contains a total of approximately 96 species, spread across sixteen genera in three subfamilies.
Diplatyidae is a family of earwigs in the suborder Neodermaptera. It contains three subfamilies, and four genera incertae sedis, one modern and three extinct known from fossils.
Karschiellidae is the sole family of earwigs in the superfamily Karschielloidea. Like the family Diplatyidae, Karschiellidae is a relatively small family with few members.
Labiduridae, whose members are known commonly as striped earwigs, is a relatively large family of earwigs in the suborder Neodermaptera.
Labiinae, whose members are commonly known as little earwigs, is a moderately sized subfamily of earwigs in the family Spongiphoridae. It is a cosmopolitan family, whose members are small, winged earwigs, generally less than 1.5 centimetres (0.59 in) in length.
This taxonomy of the Dermaptera follows Engel & Haas (2007) to the rank of genus.
Allodahlia is a genus of Asian earwigs in the family Forficulidae.
Spongiphoridae is a family of earwigs in the suborder Neodermaptera. There are more than 40 genera and 510 described species in Spongiphoridae.
Neodermaptera, sometimes called Catadermaptera, is a suborder of earwigs in the order Dermaptera. There are more than 2,000 described species in Neodermaptera.
Allodahliinae is a subfamily of earwigs in the family Forficulidae. There are at least 3 genera and about 16 described species in Allodahliinae.
Ancistrogastrinae is a subfamily of earwigs in the family Forficulidae. There are about 6 genera and more than 30 described species in Ancistrogastrinae.
Anechurinae is a subfamily of earwigs in the family Forficulidae. There are more than 70 described species in Anechurinae.
Opisthocosmiinae is a subfamily of earwigs in the family Forficulidae. There are about 18 genera and more than 100 described species in Opisthocosmiinae.
Chelidura is a genus of earwigs in the family Forficulidae from mainland Europe including southern Scandinavia.
The Spongiphorinae are a medium-sized subfamily of earwigs in the superfamily Forficuloidea, sometimes called "little earwigs", erected by Karl Wilhelm Verhoeff in 1902. Distribution records appear to be incomplete, but genera such as Spongiphora originate from the Americas including the Caribbean; certain species such as Marava arachidis, have a cosmopolitan distribution.
