The genus Ulmeritus is redefined and new generic status is given to one of its former subgenera Ulmeritoides based on new evidence from nymphal characters described here for the first time. Ulmeritus now includes the species U. balteatus Thew, U. carbonelli Traver, U. haarupi (Esben Petersen) and U. saopaulensis (Traver), which are briefly discussed. U. (Pseudulmeritus) flavopedes (Spieth) will be placed in Ulmeritoides.  The philogeny of these genera are briefly discussed.
