Palps with smooth outer surface, with inner large folds, easily view, smooth inner margin. Wide transversal ctenidial folds. Anal papilla thin walled. Pallial cardinal muscle sporadically developed. Posterior region color dark-brown, anterior and median regions vary from dark-brown to pale-green. Hermaphroditic gonad.
Widely distributed in hydrographic regions of the South America, inhabits sandy to muddy or with deposits of silt and clay, never found in gravel or rocky substrates. Also found in river with lower water velocities or in marginal lakes, where it finds food (phytoplankton) in abundnace (Refs. 126701, 126703) (Ref. 126701).
