Glossary of arthropod cuticle

This is a glossary of terms used in the description of arthropod cuticle, including that of insects such as ants. For reasons still under investigation, these animals can have surface textures spanning and combining cracks, excavations, imbrications, mealiness, punctures, reticulations, roughness, scratches, spots, wrinkles, and more. As such, hundreds of technical terms have been adapted for use in description of individual specimens from which taxa are defined.

This is a glossary of terms used in the description of arthropod cuticle, including that of insects such as ants. For reasons still under investigation,1 these animals can have surface textures spanning and combining cracks, excavations, imbrications, mealiness, punctures, reticulations, roughness, scratches, spots, wrinkles, and more (generically, 'sculpturing' or 'microsculpture'). As such, hundreds of technical terms have been adapted for use in description of individual specimens from which taxa are defined.
