Abstract:
Monticellia magna (Rego, dos Santos & Silva, 1974) is redescribed and the microtriches and their distribution are studied for the first time. This species is characterised by the following combination of characters: (1) vagina anterior to cirrus pouch; (2) muscular asymmetrical sphincter present; (3) testes in one layer and in two fields connected anteriorly and posteriorly; (4) vitelline follicles distributed cortical, paramuscular and a few follicles medullary; (5) internal longitudinal musculature strongly developed; and (6) scolex with filiform microtriches in apical region, filiform and spiniform microtriches in central cavity, marginal ring and nonadherent surface of suckers, and spiniform microtriches in neck and immature proglottides. The species parasitised fishes of Pimelodus spp. Strict specificity of South American proteocephalids for their hosts is placed into consideration since recently new host records have been reported, especially for hosts commercially exploited.
