Zygentoma

Habitus of Trinemura callawae, from Smith et al. (2012).

Belongs within: Insecta.
Contains: Lepismatidae.

The Zygentoma, silverfish, are primitively wingless insects with an elongate terminal filament between the cerci and usually a covering of scales (Grimaldi & Engel 2005). Certain members of the group are familiar as inhabitants of human houses.

Characters (from Grimaldi & Engel 2005): Compound eyes reduced or absent; ocelli usually absent. Distalmost palpal segment of labium enlarged and modified. Coxae dorsoventrally flattened, enlarged.
