<i>Irinaia brenesi</i>, nuevo tremátodo de ave de Nicaragua, América Central

Abstract

A new genus and species, Irinaia brenesi, are erected to designate a digenetic trematode parasite of a boat-billed heron, Cochlearius cochlearius zeledoni from Peñas Blancas, Nicaragua, Central America. The new taxon is placed in the family Cryptogonimidae Ciurea, 1933. The new genus approximates Acetodextra, Pearse, 1924 in the shape and structure of the seminal vesicle, but differs from it in the following characters: 1) ventral sucker situated medially in the anterior region of the body; 2) genital atrium structurally more complex; 3) uterus well developed; 4) intestinal caeca shorter; S) vitelline glands medially and laterally extra-caecal, in six or seven groups on either side.
