WAnisolabididae is a family of earwigs, in the suborder Forficulina and the order Dermaptera. It is one of nine families in the suborder Forficulina, and contains thirty-eight genera spread across thirteen subfamilies.
WArixeniidae is a family of earwigs in the suborder Neodermaptera. Arixeniidae was formerly considered a suborder, Arixeniina, but was reduced in rank to family and included in the new suborder Neodermaptera.
WChelisochidae 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.
WDiplatyidae is a family of earwigs in the suborder Neodermaptera. It contains only one subfamily, Diplatyinae, which contains six genera, five modern and one extinct known from fossils. The genus Tytthodiplatys was described in 2011 from a fossil found in Burmese amber which dates to the Albian age of the Cretaceous. It was not placed into the subfamily Diplatyinae, and is the oldest confirmed member of the family.
WForficulidae is a family of earwigs in the order Dermaptera. There are more than 70 genera and 490 described species in Forficulidae.
WHemimeridae is a family of earwigs in the suborder Neodermaptera. Hemimeridae was formerly considered a suborder, Hemimerina, but was reduced in rank to family and included in the new suborder Neodermaptera.
WLabia is a genus of earwigs belonging to the family Spongiphoridae.
WLabiduridae, whose members are known commonly as striped earwigs, is a relatively large family of earwigs in the suborder Forficulina.
WPygidicranidae is a family of earwigs, formerly placed in the suborder Forficulina, now 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.
WSpongiphoridae is a family of little earwigs in the suborder Neodermaptera. There are more than 40 genera and 510 described species in Spongiphoridae.
