The life cycle of pseudosellacotyla lutzi (Digenea: Cryptogonimidae), in aylacostoma chloroticum (Prosobranchia: Thiaridae), and Hoplias malabaricus (Characiformes: Erythrinidae), in Argentina
Pseudosellacotyla lutzi (Freitas, 1941), at present included in the Faustulidae, is redescribed, and its life cycle was resolved experimentally. The prosobranch snail Aylacostoma chloroticum Hylton Scott (Thiaridae), collected in the Yacyretá Dam, Province of Misiones, Argentina, was found naturally...
