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.[1]Nicoletiidae don’t have eyes as other existing species and they lack pigment. They have medium size, with extended antennae and terminal filaments.[2]Coletinia, a genus of this family, has many characters including a body length that ranges between 10 and 15mm. They may have yellowish pigmentation but most of them are transparent.[3] They have bilayered and very large acrosome, a short nucleus including chromatin being really condensed with tubular invaginations and sperm length and head size classified as short.
