Diagnosis

(adapted from Martens 1997). Large (1.0-3.5 mm), mostly elongated and laterally compressed Cp; marginal valve structures mostly well developed; branched pore canals and marginal septa present in some genera. Most (all?) genera with conical inclusions in the valves, visible with transmitted light as small extra pores. Anterior calcified lamella wider than posterior one; pore-canals mostly branched along ventral margin, simple and straight along anterior and posterior margins; false pore canals present (remnants of fused selvage); selvage and inner lists present or absent.

Al in some genera with large, multi-segmented Rome organs. A2 in males with larger claw Gm developed into a comb-like structure, with one row of strong teeth. C well-developed, symmetrical or asymmetrical; Att of the CR with a triangular basal reinforcement (in some genera only weakly developed). Hp with large and sclerotised bladder-like part ‘c’ of the labyrinth, postlabyrinthal internal spermiduct with up to 6 additional coils.

Tribes and genera included.
