Ctenolepisma lineata

Ctenolepisma lineata is a primitive insect of the order Zygentoma. It is generally similar to the closely related silverfish but can be distinguished by being rather stouter and less shiny with all appendages (antennae and 3 "tails") noticeably longer. The abdomen is often marked with dark brown lines and the species is sometimes called four-lined silverfish.

This species is native to southern Europe but is now found throughout most of the world as an accidental introduction although it is absent from polar and cooler temperate regions (e.g. the British Isles). It is found both indoors and outdoors and can be a nuisance pest.

Recent studies on this species in Europe suggest that there is enough geographical variation to justify splitting into several species, with one form already having been given specific status as Ctenolepisma almeriensis from south-eastern Spain.[1]

Lepisma pilifera Lucas, 1840, which was considered a synonym of C. lineata, is now treated as a synonym of Thermobia aegyptiaca (Lucas, 1840).[2]
