Cartilage element that lies between processes of the cleithrum and pelvic girdle in gobioid fishes. Posterodorsal to the ventral end of each cleithrum is a posteriorly projecting process. The pelvic intercleithral cartilage (an unpaired, median structure) forms a bridge between the processes (From Springer, 1983).
