Arixeniidae is a family of earwigs; it is the only family in the suborder Arixeniina (one of the four suborders of the order Dermaptera). The other three suborders are Archidermaptera, which is extinct, Forficulina, the largest of the four, and Hemimerina. Arixeniidae is represented by two genera, Arixenia and Xeniaria with a total of five species in them: [2] Arixenia esau , [3] [4] and Xeniaria jacobsoni [5] being the most well-known. As with Hemimerina, they are blind, wingless ectoparasites with filiform segmented cerci. They are ectoparasites of various Southeast Asian bats, particularly of the genus Cheiromeles (i.e., "naked bulldog bats").
Earwigs make up the insect order Dermaptera. With about 2,000 species in 12 families, they are one of the smaller insect orders. Earwigs have characteristic cerci, a pair of forceps-like pincers on their abdomen, and membranous wings folded underneath short, rarely used forewings, hence the scientific order name, "skin wings". Some groups are tiny parasites on mammals and lack the typical pincers. Earwigs are found on all continents except Antarctica.
Forficulina is the largest of the four suborders of earwigs, in the order Dermaptera. The other three are Archidermaptera, which is extinct, Arixeniina, and Hemimerina. They make up the largest and most familiar group. The cerci are unsegmented, and modified into large, forcep-like structures. Females have unhooked cerci, while males have hooked cerci.
Arixenia is a genus of earwigs, one of only two genera in the family Arixeniidae, and contains two species.
The suborder is spelled Arixeniina, not Arixenina. [6] [7] [8]
The family includes the following genera:
Cerci are paired appendages on the rear-most segments of many arthropods, including insects and symphylans. Many forms of cerci serve as sensory organs, but some serve as pinching weapons or as organs of copulation. In many insects, they simply may be functionless vestigial structures.
Arixenia esau is a species of earwig, one of three species in the genus Arixenia.
Xeniaria jacobsoni is a species of earwigs, in the genus Xeniaria, family Arixeniidae, the suborder Arixeniina, and the order Dermaptera. It is one of three genera in the genus Xeniaria.
Xeniaria truncata is a species of earwigs, in the genus Xeniaria, family Arixeniidae, the suborder Arixeniina, and the order Dermaptera. It is one of three genera in the genus Xeniaria.
Hemimeridae is a family of earwigs, the only family in the suborder Hemimerina, one of the four suborders in the order Dermaptera. The other three suborders are Archidermaptera, which is extinct, Arixeniina, and Forficulina, the largest of the four. Hemimeridae is represented by two genera, Hemimerus and Araeomerus. They are wingless, blind and viviparous ectoparasites of African rodents, and have filiform segmented cerci. The best known species is Hemimerus bouvieri. Hemimeridae contains eleven described species placed within two genera: Hemimerus and Araeomerus. Hemimerids are relatively small (5–15 mm) and inhabit the fur of giant murid rats in Africa. Hemimerids have short, broad legs with grooves that allow them to cling to the host and specialized mouthparts for scraping dead skin and fungus from their host. Araeomerus is found in the nest of long-tailed pouch rats (Beamys) and Hemimerus is found on giant (Cricetomys) rats. Araeomerus are found more often in the burrows and nests of Beamys rat than on the rat itself, while Hemimerus less frequently leaves its host.
Hemimerus is a genus of earwigs, in the family Hemimeridae. It one of two genera in the family Hemimeridae, and contains ten species:
Asiodiplatys speciousus is an extinct species of earwig in the family Protodiplatyidae. It is the only species in the genus Asiodiplatys. It had long and thin cerci that were very different from modern species of Dermaptera, but tegmina and hind wings that folded up into a "wing package" that are like modern earwigs. Like Archidermapteron martynovi, the only clear fossil of the species was found in Russia.
Anisolabididae 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.
