Descriptions of Neolebouria tinkerbellae n.sp. (Trematoda: Digenea: Opecoelidae) from experimental fish hosts, and of metacercariae of N. tinkerbellae and an unidentified digenean from Pandalus jordani (Decapoda: Penaeidae) from the Pacific coast of Canada

Abstract

Neolebouria tinkerbellae n.sp. (Trematoda: Opecoelidae) is described from specimens obtained from experimental infections in Platichthys stellatus (Pallas), Gasterosteus aculeatus Linnaeus, and Leptocottus armatus Girard. The metacercarial stage occurs in the heart muscle of Pandalus jordani Rathbun (smooth pink shrimp) from the Pacific coast of Canada and forms a translucent white cyst. A second, unidentified species of metacercaria found in P. jordani forms a cyst surrounded by a brown pigmented layer in the somatic musculature. Both metacercariae are described.
