Conteúdo:

Acanthostomum gnerii is a digenean frequently reported from intestine of Siluriformes and it is
well distributed over Central and South America. The aim of this study is to provide additional
information on morphological features of A. gnerii by histological sections and scanning
electron microscopy, as well as to provide comparative measurements of Acanthostomum spp. In
contrast to previous reports of this helminth in Rhamdia sp., specimens in the present study
showed two arms in the anterior portion of the body, just after the pharynx. They join and
terminate in one lateral pore on the left side of the body similar to that reported in A.
proctophorum and A. minimum. Such morphology was not described as a valid characteristic for
Acanthostomidae. This morphological variation could be associated with different populations
of the same species. New studies using molecular techniques are recommended to determine if
this character corresponds to a diversity of A. gnerii found in other fish species.
