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.
Highlights
Systematic studies of the marine digenean fauna of New Caledonia were by Durio & Manter (1968a), Durio & Manter (1968b) and Durio & Manter (1969)
The electronic version of this article in Portable Document Format (PDF) will represent a published work according to the International Commission on Zoological Nomenclature (ICZN), and the new names contained in the electronic version are effectively published under that Code from the electronic edition alone
The two Indo-Pacific species that are described with this feature are the type-species, Z. viviparus (Olsson, 1868), and Z. yamagutii Kamegai, 1973
Summary
Systematic studies of the marine digenean fauna of New Caledonia were by Durio & Manter (1968a), Durio & Manter (1968b) and Durio & Manter (1969). We present a similar paper summarising our knowledge of the family Zoogonidae Odhner, 1902 This family is one of the major families of marine fish digeneans, with a few species in freshwater (Bray, 2008). It contains 159 species in 33 genera. Molecular analyses of a few species (Hall, Cribb & Barker, 1999; Cribb et al, 2001; Olson et al, 2003; Bray et al, 2005; new data) shows that the family is a member of the superfamily Microphalloidea Ward, 1901, close to, and probably paraphyletic to the family Faustulidae Poche, 1926. In this paper we list all the known species, including a new species of the genus Overstreetia (Bray, 1985), and attempt to place them in the context of their endemicity
