A review of the Zoogonidae (Digenea: Microphalloidea) from fishes of the waters around New Caledonia, with the description of Overstreetia cribbi n. sp

Rodney A Bray et al. PeerJ. 2014.

Abstract

New and published reports of zoogonid digeneans from New Caledonian waters are recorded, including a description of Overstreetia cribbi n. sp. from Atherinomorus lacunosus. This species differs from its congeners in the detail of its circum-oral spination and some metrical features. Other new records are of: Diphterostomum plectorhynchi Machida, Kamegai & Kuramochi, 2006 in Diagramma pictum; Parvipyrum acanthuri (Pritchard, 1963) in Acanthurus dussumieri; Zoogonoides viviparus (Olsson, 1868) in Lagocephalus sceleratus; Deretrema ? combesorum (Bray & Justine, 2008a; Bray & Justine, 2008b) early ovigerous forms in Parupeneus pleurostigma; D? acutum (Pritchard, 1963) in P. barberinus; and an unidentified immature zoogonid in P. multifasciatus. The newly reported specimens are illustrated and measurements given. The distribution of New Caledonian zoogonids is listed.

Keywords: Atherinomorus; Digenea; Fish parasite; New Caledonia; Overstreetia cribbi n. sp.; Zoogonidae.
