Sôbre uma nova espécie do gênero Lecithochirium Luehe, 1901: (Trematoda, Hemiuroidea)

In this paper a new species of the genus Lecithochirium Luehe, 1901, is described. To simplify the study of this genus, we divided it in 3 groups according principally to the relation among the suckers. L. manteri sp. n., comes nearest to L. texanum, L. priacanthi, and L. microstomum, but differes mainly from them by the great size of the suckers, pharynx and eggs.
