Redescription of Monticellia magna (Rego, dos Santos & Silva, 1974) (Eucestoda: Monticelliidae) parasite of Pimelodus spp. (Pisces: Siluriformes) from Argentina, and morphological study of microtriches

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...
