This main chitinous layer of the cuticle is called the procuticle. The procuticle in most land Arthropoda, particularly insects, is covered externally with a thin, waxy, water-resistant outer layer containing no chitin. That outer layer is the epicuticle, and it is much thinner than the procuticle. See more The cuticle forms the major part of the integument of animals in the phylum Arthropoda.
