Porangatus ceteyus n. gen., n. sp. (Digenea: Zoogonidae): A Parasite of Hoplosternum littorale (Pisces: Callichthyidae) from Amazonas State, Brazil

Abstract

Porangatus ceteyus n. gen., n. sp. is erected to accommodate some specimens of Digenea recovered from the intestine of Hoplosternum littorale. Hosts were collected in lakes located near the junction of the Solimões and Negro rivers, Amazonas State, Brazil. The new genus differs from the others in the family mainly in the distribution of vitellarium, consisting of 2 lateral groups extending from the level of the anterior margin of the ventral sucker, where they may be confluent, to near the posterior end of body, occupying cecal, extracecal and intercecal areas.
