Adult Anatomy

The lower part of the mesothoracic episternum. It is separated from the dorsal mesothoracic episternum (anepisternum or mesopleuron) by the anapleural suture.

Accordingly to McAlpine (1981) the mesothoracic katepisternum is frequently, but incorrectly called the sternopleuron (as in Steiner 1976). Although in Diptera the mesosternum (ventral sclerite of the mesothorax) is greatly reduced and internalized, it is not fused with the katepisternum, and thus the latter should not be called sternopleuron. However, it seems that most publications still use the term sternopleuron (or sternopleurite) to refer to the katepisternum - https://orcid.org/0000-0001-5948-3092.
