Digenean parasites of Cariama cristata (Aves, Gruiformes) from Formosa Province, Argentina, with the description of a new species of the genus Strigea

Abstract

A new strigeid digenean, Strigea inflecta sp. nov., is described from the small intestine of the Red-legged Seriema, Cariama cristata (L.) (Gruiformes, Cariamidae) from Formosa Province, Argentina. This species is characterized by having a body plump, a cup-shaped forebody with a large opening, a sacciform hindbody, without a neck region and strongly curved dorsally, a poorly delimited copulatory bursa, wider than longer, a shallow and asymmetrical genital atrium, and a genital cone well delimited from body parenchyma, strongly muscular, inclined towards the surface ventral of the body. Another digenean species collected from Red-legged Seriema, Brachylaima yupanquii Freitas, Kohn et Ibáñez, 1967 (Brachylaimidae) is described with the addition of new morphological characters and morphometrical data. This species is reported for the first time in Argentina and C. cristata represents a new host record.

First report of the genus Brachylaima Dujardin, 1843 (Trematoda: Brachylaimidae)from the small intestine of common myna (Acridotheres tristis) of district Swabi,Khyber Pakhtunkhwa, Pakistan

“…The family Brachylaimidae consists of seven genera (Lunaschi and Drago, 2012) (Dujardin, 1843) Kruidenier & Gallicchio, 1959Brachylaema Yamaguti, 1958;andBrachylaima (Dujardin, 1843) Yamaguti, 1971. These include species of trematodes parasitizing birds and mammals.…”

Digenean parasites of the great antshrike, Taraba major (Aves: Thamnophilidae), from Argentina, with a description of a new species of the genus Strigea (Strigeidae)

“…remarks. Among Neotropical species of Strigea, only five species, Strigea caluri Dubois, 1962, Strigea nugax szidat, 1928, Strigea sphaerocephala (Westrumb, 1823, Strigea elliptica (Brandes, 1888) and Strigea inflecta lunaschi et Drago, 2012, can be compared with Strigea orbiculata sp. n. by having a body plump and vitelline glands extensively distributed throughout the forebody.…”

Zamparo et al (2003b) erected the genus Pojmanskia to contain specimens found parasitizing several species of birds from Costa Rica.…”
