Redescription and distribution of Mastigodiaptomus montezumae (copepoda, calanoida, diaptomidae) in Mexico

Abstract

Mastigodiaptomus montezumae is redescribed on the basis of material from several localities in Mexico. It is characterized by an asymmetrical fifth pediger in both sexes. It appears to be restricted to central Mexico, where it is quite common. It is associated with M. albuquerquensis and occasionally with L. siciloides and Leptodiaptomus novamexicanus.
