| morphological variability, ultrastructure and molecular characterisation of hysterothylacium reliquens (norris & overstreet, 1975) (nematoda: raphidascarididae) from the oriental sole brachirus orientalis (bloch & schneider) (pleuronectiformes: soleidae). | hysterothylacium reliquens (norris & overstreet, 1975), a common ascaridoid nematode parasitic in the marine fishes in the indian and atlantic oceans, has been reported to exhibit remarkable morphological variability in the lengths of body, oesophagus and spicules, and the number and arrangement of postcloacal papillae. in order to determine whether h. reliquens with a broad range of morphological variability in the above-mentioned respects, represents a complex of sibling species or a single sp ... | 2017 | 27677942 |
