The posterior or rear segment of the body in certain parasitic protozoans, as distinct from the anterior promerite.
From Greek deuteros (second) + -merite (part of a body segment). A protozoology term describing the 'second part' of a body in segmented organisms.
Gregarines are weird parasites with two very different body sections, and the deutomerite is the back half that does most of the reproductive work—nature's way of dividing labor within a single organism!
