“…We further predict that minor genetic variation of this kind will be discovered more and more frequently in trematodes of Indo-Pacific fishes. In this system the disparity between the dispersal capacity of the host fish and their parasites (Cribb et al, 2000) is likely to promote exactly this effect.…”

Cryptic species of Euryakaina n. g. (Digenea: Cryptogonimidae) from sympatric lutjanids in the Indo-West Pacific

A survey of the endohelminth fauna of Indo-West Pacific Lutjanidae (Perciformes) revealed the presence of the species Siphoderina manilensis (Velasquez, 1961) Miller & Cribb, 2008 and S. marina (Hafeezullah & Siddiqi, 1970) Miller & Cribb, 2008 in seven Lutjanus spp. from sites off the Great Barrier Reef, the Maldives, New Caledonia and Ningaloo Reef, Western Australia. A combination of morphological and ribosomal DNA analyses of these cryptogonimids prompted the transfer of these taxa to a new genus, Euryakaina n. g., as E. manilensis n. comb. and E. marina n. comb., based on comparative analysis with other cryptogonimid taxa. Euryakaina n. g. is distinguished from all other cryptogonimid genera by the combination of a fusiform body, the few relatively small, widely spaced oral spines (sometimes absent), a highly lobed ovary, opposite to slightly oblique testes, vitelline follicles that extend from the anterior margin of the testes to slightly posterior to the intestinal bifurcation, and an excretory vesicle that bifurcates dorsal to the ovary and reunites briefly slightly posterior to the intestinal bifurcation. Morphometric analysis of these taxa alone suggests they should be reduced to synonymy, but DNA sequence analyses and ecological niche partitioning provide evidence that they form a cryptic species complex in sympatric lutjanids in the Indo-West Pacific. The secondary structure of the ITS2 rDNA for species of Euryakaina was also modelled and analysed for the presences of compensatory base changes (CBCs) or hemi-CBCs in order to explore the usefulness of these changes as a tool to help elucidate the taxonomy of this complex system. We also report what we interpret here as intraspecific variation in the ITS2 rDNA between individuals of E. manilensis from Lutjanus vitta recovered off the Great Barrier Reef and New Caledonia.

“…Likewise, reef fish ecologists have done little work of this type. However, Cribb et al (2000) recently identified 13 different parasite species infesting 23% of settling reef fish in New Caledonia. If the spatial distribution of these parasites in the pelagic environment can be mapped, they might provide valuable information about waters through which larvae have moved and, therefore, connectivity.…”

“…This impoverishment of the parasite fauna in islands is reminiscent of similar differences in various organisms (Bellwood andHughes 2001, Karlson et al 2004) and suggests that a West-East gradient of biodiversity in the Pacific is involved for monogenean fish parasites as it is the case for free-living species. Cribb et al (2000) predicted that 'the more remote coral reefs of the IndoPacific will prove to have depauperate parasite faunas because of the problem of dispersal'. However, Plaisance et al (2005) found a richer fauna of monogeneans in butterflyfishes of Moorea than in the Western part of the Pacific Ocean.…”

New material from Epinephelus quoyanus collected from Heron Island, Australia and material collected by Young in the same locality, allegedly from E. merra, and deposited in the Queensland Museum, contained the same three species of diplectanid monogeneans: Pseudorhabdosynochus cupatus (Young, 1969), P. vagampullum (Young, 1969, and P. justinei Zeng et Yang, 2007 (new record for Australia). In contrast, E. merra in New Caledonia harbours only P. melanesiensis (Laird, 1958). It is concluded that the type-host of P. cupatus and P. vagampullum is not E. merra, as indicated in Young (1969), but E. quoyanus, and that P. cupatus sensu Young comprises two species, P. cupatus from E. quoyanus and P. youngi sp. nov. from E. fasciatus. P. youngi sp. nov. is described from E. fasciatus from New Caledonia (type-locality), Heron Island, and French Polynesia, and distinguished from P. cupatus on the basis of the male quadriloculate organ, sclerotised vagina and lamellosquamodiscs. Thus, P. cupatus, P. melanesiensis and P. youngi each have a single host, respectively E. quoyanus, E. merra, and E. fasciatus. Results for E. fasciatus and E. merra in New Caledonia, Wallis and French Polynesia suggest impoverishment of the monogenean fauna in a West-East gradient in the Pacific.
