Ctenolepisma Explained

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.^[1]

Nomenclature

Most authors have historically treated the nomenclatural gender of Ctenolepisma as feminine, but in 2018 the International Commission on Zoological Nomenclature issued a formal ruling (ICZN Opinion 2427) stating the gender of Lepisma (and all genera with that ending) is neuter, following ICZN Article 30, which resulted in changes to the spelling of several well-known species, including Ctenolepisma longicaudatum (formerly longicaudata).^[2]

Diversity

There are roughly 75 extant species presently recognized as valid in the genus, and one fossil^[3]
