| molecular and morphological comparisons between gyrodactylus ostendicus n. sp. (monogenea: gyrodactylidae) on pomatoschistus microps (krøyer) and g. harengi malmberg, 1957 on clupea harengus membras l. | gyrodactylus ostendicus n. sp. was exclusively found on fins of the common goby pomatoschistus microps (krøyer). the haptoral hard parts are among the smallest described for species of gyrodactylus. a presumed similarity between the new species and g. harengi malmberg, 1957 (subgenus metanephrotus malmberg, 1964) encouraged a comparative approach. a morphological analysis showed the marginal hook sickles of g. ostendicus to be of quite a different type and similar to those of g. arcuatus bychows ... | 2004 | 15449826 |
