What is "ctenolepisma"

Ctenolepisma is a genus of primitive insects (order Zygentoma = Thysanura s.s.) 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.
