A helical thickening found in the cuticle of the tracheae of arthropods, ensuring that the tracheal tubes remain open and do not collapse.

From Latin 'taenia', meaning 'band' or 'strip', and '-idium', meaning 'a small thing'.
Example
The taenidia in the tracheal system of insects prevent the tubes from collapsing, thereby maintaining efficient air flow.
