Lepismatidae is a family of primitive wingless insects with about 190 described species. This family contains the two most familiar members of the order Zygentoma: the silverfish (Lepisma saccharinum) and the firebrat (Thermobia domestica). It is one of five families in the order Zygentoma.
Lepismatids are elongated, flattened insects, the majority of which are scavengers. The abdomen is usually clothed in tiny scales and terminates with three "tails" of roughly equal length. The compound eyes are small and well separated.
They typically live in warm, damp environments, including indoors. They avoid light. [2]
These genera belong to the family Lepismatidae: [3] [4] [5] [6]
Member of the Strepsiptera family Mengenillinidae exclusively parasitise members of Lepismatidae. Host-species relationships include: Eoxenos laboulbenei on Tricholepisma aureum , Neoasterolepisma wasmanni and N. palmonii; Mengenilla parvula on Sceletolepisma michaelseni ; Mengenilla nigritula on Ctenolepisma ciliatum and Ctenolepisma sp.; Mengenilla laevigata, M. quasita, M. spinulosa and M. subnigrescens on C. lineatum; and an unidentified species of Strepsiptera on Mormisma peyerimhoffi. [7]
Parasitic Apicomplexa are often found in the intestinal tract, especially the crop, of Lepismatidae. Ctenolepisma lineatum contains on average 15 parasite specimens per animal. [8] Several species of gregarine parasites have been recorded from the intestinal tract of the gray silverfish: [7]

Lepisma is a genus of primitive insects in the order Zygentoma and the family Lepismatidae.
The Machilidae are a family of insects belonging to the order Archaeognatha. There are around 450 described species worldwide. These insects are wingless, elongated and more or less cylindrical with a distinctive humped thorax and covered with tiny, close-fitting scales. The colour is usually grey or brown, sometimes intricately patterned. There are three "tails" at the rear of the abdomen: two cerci and a long central epiproct. They have large compound eyes, often meeting at a central point. They resemble the silverfish and the firebrat, which are from a different order, Zygentoma.
Zygentoma are an order in the class Insecta, and consist of about 550 known species. The Zygentoma include the so-called silverfish or fishmoths, and the firebrats. A conspicuous feature of the order are the three long caudal filaments. The two lateral filaments are cerci, and the medial one is an epiproct or appendix dorsalis. In this they resemble the Archaeognatha, although the cerci of Zygentoma, unlike in the latter order, are nearly as long as the epiproct.
Ctenolepisma is a genus of primitive insects in the order Zygentoma, closely related to the silverfish and firebrat but less reliant on human habitation, some species being found both indoors and outdoors and some found exclusively outdoors. The genus is distributed nearly worldwide in warm regions. Australia lacks native Ctenolepisma, but is home to introduced species.
Ctenolepisma lineatum is a species of insect of the order Zygentoma. It is similar to the closely related silverfish but can be distinguished by being rather stouter and less shiny with all appendages noticeably longer. The abdomen is often marked with dark brown lines and the species is sometimes called four-lined silverfish.
A silverfish is a wingless insect in the order Zygentoma. The same name can be applied to many species in the order as a whole, which comprises the families Lepismatidae, Nicoletiidae, Lepidotrichidae, Maindroniidae and Protrinemuridae.
The Meinertellidae are a small family of basal insects belonging to the order Archaeognatha. They are sometimes known as rock bristletails. These insects can be distinguished from members of the other Archaeognatha family, Machilidae, by the lack of scales at the base of the legs and antennae, head, and palps; along with possession of small abdominal sternites protruding slightly between the coxal plates. They can also be distinguished by patches of reddish to violet-brown hypodermal pigment on the appendages.
Neoasterolepisma is a genus of primitive insects belonging to the family Lepismatidae. Many species live with ants.
Lepidospora is a genus of silverfish in the family Nicoletiidae.
Nicoletia is a genus of silverfish in the family Nicoletiidae. As of 2007, it contains the former members of two other genera.
Tricholepidion is a genus of wingless insect belonging to Zygentoma, with only a single described species T. gertschi, native to the northern coast of California in Western North America. It lives under dead bark and in rotting wood of conifers in mesophytic forests. It is alternatively considered the only living member of the family Lepidotrichidae, which also includes Lepidotrix from Eocene aged European amber, or the only member of the family Tricholepidiidae. The taxonomic position of Tricholepidion is uncertain, in some molecular phylogenetics studies it has been recovered as less closely related to flying insects (Pterygota) than the rest of Zygentoma is, rendering Zygentoma paraphyletic. Each compound eye contains ~40 ommatidia, and they have three ocelli. Scales on the body are absent. Unlike Archaeognatha and the other families of Zygentoma, which have three- and sometimes two-segmented tarsi, they have five-segmented tarsi like many winged insects.
Stylifera is a genus of silverfish in the family Lepismatidae. There are at least two described species in Stylifera.
Thermobia aegyptiaca is a species of silverfish in the family Lepismatidae. The species was described by Hippolyte Lucas in 1840 based on specimens collected in Egypt. Thermobia aegyptiaca is distributed in Africa and the eastern Mediterranean Basin.
Neoasterolepisma gauthieri is a species of silverfish in the family Lepismatidae.
Sceletolepisma albidum is a species of silverfish in the family Lepismatidae.
Sceletolepisma canariense is a species of silverfish in the family Lepismatidae.
Ctenolepisma terebrans is a species of silverfish in the family Lepismatidae.
Ctenolepisma longicaudatum, generally known as the gray silverfish, long-tailed silverfish or paper silverfish, is a species of Zygentoma in the family Lepismatidae. It was described by the German entomologist Karl Leopold Escherich in 1905 based on specimens collected in South Africa, but is found worldwide as synanthrope in human housings.
Sceletolepisma is a genus of primitive insects closely related to the silverfish and firebrat but less reliant on human habitation, some species being found both indoors and outdoors and some found exclusively outdoors. The genus is distributed nearly worldwide in warm regions.
Cretalepisma is an extinct genus of wingless insect belonging to family Lepismatidae in the order Zygentoma. It contains one species, Cretalepisma kachinicum. Cretalepisma is known from a single female specimen, preserved in Cretaceous aged Burmese amber. The specimen has a total body length of 9.7 millimeters, almost twice that of Burmalepisma.
