Lauridae: Taxonomy and morphology of ascothoracid crustacean parasites of zoanthids
Abstract:A provisional list of diagnostic features of the Lauridae and a table of characters distinguishing the contained genera are given. Females of Laura bicornuta new species from Hawaii (hosts Gerardia sp. and an unidentified zoanthid) and L. dorsalis new species from Florida (host Epizoanthus sp.) are described and compared with L. gerardiae Lacaze-Duthiers from the Mediterranean (host Gerardia savaglia). An unnamed female specimen of Baccalaureus Broch from Raroia Atoll, French Polynesia (host Palythoa sp.) is described; it also serves as the basis for a reinterpretation of tagmosis in that genus, which is thereby shown to require taxonomic revision. The anterior "horns" are interpreted as originally dorsolateral thoracic projections, not homologous with the "filamentary appendages" of Isidascus Moyse, for example. Females, males, and a carapace valve of a presumed ascothoracid larva of Zoanthoecus cerebroides new genus and species from Hawaii (host Gerardia sp.) are described. Baccalaureus digitatus Pyefinch is redescribed and assigned to a new, monotypic genus, Polymarsypus. Nauplii of L. bicornuta, L. dorsalis, Z. cerebroides, and P. digitatus are described. Both new Laura species and Z. cerebroides are occasionally infested with cryptoniscid isopods, L. dorsalis by two species. The range extensions of Laura and Baccalaureus documented here make earlier historical-biogeographical interpretations of this family untenable.
