Abstract

A survey of the parasites of Indo-West Pacific Haemulidae revealed the presence of three new cryptogonimid (Digenea: Cryptogonimidae) species warranting two new genera, Beluesca littlewoodi n. gen., n. sp. and B. longicolla n. sp. from the intestine and pyloric caeca of Plectorhinchus gibbosus and Chelediadema marjoriae n. gen., n. sp. from the intestine and pyloric caeca of Diagramma labiosum, P. albovittatus and P. gibbosus from Heron and Lizard Islands off the Great Barrier Reef, Australia. Beluesca n. gen. is distinguished from all other cryptogonimid genera by the combination of an elongate body, funnel-shaped oral sucker, relatively small number of large oral spines, highly lobed ovary, opposite to slightly oblique testes, uterine loops that are restricted to the hindbody and extend well posterior to the testes and vitelline follicles that may extend from the ovary into the forebody, but do not extend anterior to the intestinal bifurcation. Pseudallacanthochasmus plectorhynchi Mamaev, 1970 is transferred to Beluesca as B. plectorhyncha (Mamaev, 1970) n. comb. based on morphological and ecological (host preference) characteristics. Chelediadema n. gen. is distinguished from all other cryptogonimid genera by the combination of a lanceolate body, relatively small number of large oral spines, prepharynx that is much longer than the oesophagus, tandem testes, uterine loops that are extensive in the hindbody and extend well posterior to the testes and vitelline follicles that extend from the ovary to the pharynx. Morphological analysis of the three species described here was augmented with DNA sequence analyses utilizing data from the large subunit (LSU) and the internal transcribed spacers (ITS) 1 and 2, and 5.8S nuclear ribosomal DNA. Sequence data from the LSU and ITS (encompassing the ITS1, 5.8S and ITS2) of the taxa examined here were aligned with those reported for other cryptogonimids, Caulanus thomasi, Latuterus tkachi, Neometadena ovata, four representative species of Retrovarium and an undescribed species of Siphoderina, for comparative purposes and to explore levels of interspecific and intergeneric variation among these taxa. Minimum evolution analysis was conducted on a combined (LSU and ITS) dataset to explore relationships among these genera. Despite their superficial morphological and host preference similarities, species of Beluesca and Chelediadema were genetically distant from each other. Interspecific and intergeneric variation among the species described here is similar to that reported for other cryptogonimids.
