Description:

The erythrinid fish Hoplias malabaricus in Paraguay harbour two species of proteocephalid cestodes, Proteocephalus regoi sp. n. and Nomimoscolex matogrossensis Rego et Pavanelli, 1990. The former species differs from most South American members of Proteocephalus from fishes by: 1) presence of a small apical organ, 2) distribution of vitellaria, which do not reach to posterior margin of segment and 3) posterior position of vagina. Nomimoscolex matogrossensis is redescribed on the basis of type and recent material, with emphasis given to the morphology of genital organs and scolex, which possesses an apical organ. Both species possess a dense network of osmoregulatory canals in the postacetabular region of both scolex and neck. Proteocephalus regoi sp. n. is the first representative of the subfamily Proteocephalinae parasitizing erythrinid fish.
