Dear Marco,
during the last years we were doing some taxonomic work on worldwide splanchnotrophids. First on (eastern Pacific and Caribbean) Ismaila, and then on Indo-Pacific genera (see references). We also examined some species of the eastern Atlantic and Mediterranean genera Splanchnotrophus and Lomanoticola. We found that, unfortunately, the old original descriptions of Splanchnotrophus species are not detailed enough to allow proper reidentification (unpublished). We don't know anything about potential morphological variability of species involved either. Our current believe that Splanchnotrophus species can infest different host species may be wrong, since all species of the better explored genera appear to be host-specific.
As many parasites as possible (and of different hosts) should be collected and compared. Best would be fixation with ethanol (90-100%) to also allow molecular work.
