paratergites

Paratergites are small, paired sclerites found on the dorsal surface of insect abdominal segments. They are typically located laterally to the tergites, which are the main dorsal plates of the abdomen. The exact position and morphology of paratergites can vary significantly among different insect groups. In some insects, they may be reduced or absent, while in others, they can be quite prominent. Paratergites are often described as lateral extensions or outgrowths of the tergite.

The primary function of paratergites is generally considered to be related to the musculature of the abdomen. They can serve as attachment points for muscles that control abdominal movement, such as those involved in locomotion, respiration, or reproduction. In some species, paratergites may also play a role in protecting the delicate intersegmental membranes. Their presence and form can be important taxonomic characters used in the identification and classification of insects, particularly within certain orders. Detailed studies of paratergite morphology are often conducted in entomological research to understand insect anatomy and evolutionary relationships.
