Subterranean silverfish

Nicoletiidae is a family of primitive insects belonging to the order Zygentoma. These insects live primarily underground, under detritus, or in caves. A few species are recorded as commensals inside nests of social insects, such as the species Allotrichotriura saevissima which lives inside fire ant nests. Nicoletiids lack eyes and they lack pigmentation. They have long antennae and terminal abdominal filaments. Coletinia, a genus of this family, range in size between 10 and 15mm, and may have yellowish pigmentation but most species are transparent.
