Opistho genital gonophore is present in the terminal segment in Chilopoda.
A gonopore, sometimes called a gonadopore, is a genital pore in many invertebrates. Hexapods, including insects, have a single common gonopore, except mayflies, which have a pair of gonopores.
Chilopoda is any of various long, flattened, many-segmented predaceous arthropods. Each segment except the hindmost bears one pair of legs. In these, gonopores are close to the animal's tail that is in the terminal segment.
