Abstract Trichocorixella mexicana (Hung.), a corixid, has dextral and sinistral males and bilaterally symmetrical females. The development of this polymorphic form from ovum to adult shows five nymphal instars. Thus, this species must be added to the list of polymorphic Corixidae that have five nymphal instars in their life history.
