Carryng on the work related to the Brazilian Procamallanus, we rectify a few statements as well as confirm several ones appraising former species proposed and inserted in this paper and arise a new one. 1. procamallanus (S.) solani n. sp. was related to the nearest four brazilian species and their relationship is displaied on table I. 2 Procamallanus (S.)inheringi Travassos, Artigas & Pereira, 1928. The aspect of buccal capsule in males and females of our material was absolutely not that one described by Travassos & cols., since they were mistaken in their description, inverting the number of spiral thickenings in the buccal capsule of the latter. In order to compare our material with that assigned as type, we present camera lucida drawings and photomicrographies of both samples. 3. Procamallanus (S.) inopinatus Travassos, Artigas & Pereira, 1928. Its description and drawings were abridged and adapted from Pinto & Noronha, 1972. 4. Procamallanus (S.) amarali Vaz & Pereira, 1934. We found among fully males of the species, only tiny and diaphanous immature female nematodes in which we could observe the genitalia and buccal capsule in several developing phases. A sole young female speciment, owing a very short, smooth and thin walled ovejector was the basis for the description we present.
