SANTOS, Cláudia P.; BIANCHI, Luciane G.  and  GIBSON, David I.. Acleotrema lamothei n. sp. (Monogenea: Diplectanidae) from the gills of Kyphosus incisor in Brazilian waters. Rev. Mex. Biodiv. [online]. 2008, vol.79, suppl., pp.69-73. ISSN 2007-8706.

A diplectanid monogenean, Acleotrema lamothei n. sp., is described from the gills of the yellow sea chub Kyphosus incisor (Cuvier, 1831) in Brazilian waters off Rio de Janeiro State. This species is distinguished by the facts that the male copulatory organ is armed with spines throughout most of its length, the ventral hamuli have a very long, stout outer root, which is slightly notched proximally, an inner root less than half the length of the outer root and a fine blade and point. It also differs from most species of the genus by the greater size of the haptor and its hard parts. This is the first record of a species of Acleotrema Johnston and Tiegs, 1922 from South American waters.

Keywords : Monogenea; Diplectanidae; Acleotrema lamothei n. sp.; Kyphosus incisor; Brazil.
