As sister group to Insecta (sensu stricto), Diplura are key to understanding the early evolution of hexapods and the origin and evolution of insects. Here we report the 1.2-Gbp draft genome of C. augens and results from comparative genomic analyses with other arthropods. Possibly reflecting adaptation to soil life, we identiAed a paucity of photoreceptor genes, and by contrast the largest chemosensory gene repertoire of ionotropic receptors in the animal kingdom. Expansions of detoxiAcation and carbohydrate metabolism gene families likely reflect adaptations for foraging behaviour, and duplicated apoptotic genes might underlie its high regenerative potential. The C. augens genome represents a key reference for studying the emergence of genomic innovations in insects, the most diverse animal group, and opens up novel opportunities to study the under-explored biology of diplurans.
