Zoology. 27. 3 mm : Lateral view of the Suspensorium of Opsariichthys bidens illustrating the presence of a dentate suture bet- ween metapterygoid and symplectic that is indicated by arrows ( mm standard length; PC 22). Ent: entopterygoid; hy: hyomandibula; mtg: metapterygoid; sy: symplectic; q: quadrate. The large entopterygoid slightly overlaps the posterior part of the autopalatine, which is unusual among teleosts. The posterior part of the entopterygoid is medial to the metapterygoid, and to a small area to the quadrate. The elongate, blade-like ectopterygoid does not reach the autopalatine anteriorly, and it is medial to the quadrate posteriorly. A suture between the ectopterygoid and quadrate is missing, instead a short ligament connects them. The metapterygoid is a large bone, with serrate or dentate anterior and posteroventral margins. It has a well developed processus basalis, separated by a notch from the posterior part of the bone. Anteroventrally, there is a synchondral joint between the metapterygoid and quadrate. A deep notch (part of the wall of the quadrate-metaptery- goid fossa) separates the articular border with the quadrate from the serrated posteroventral margin. The posterior margin bears two articular surfaces; the dorsal one for the anteroventral part of the hyomandibula, the ventral one for the cartilage between the hyomandibula, symplectic, and interhyal. The quadrate has a complex shape. The main body is separated by a deep notch from the posteroventral process; this process is broad and lateral to part of the anterior pro-.
