apterygote
Dipluran (Japygidae)
A typical apterygote has six legs.1
The presence of six legs was historically a defining characteristic used to identify true insects and categorize the various groups within the traditional subclass Apterygota, which includes proturans, collembolans, diplurans, and members of the orders Zygentoma and Archaeognatha. While the taxonomic classification of these groups has evolvedâwith some now considered independent classes rather than true insectsâthey remain grouped together in discussions due to their shared status as primitive hexapods.12
