| morphological variability of dicrogaster contracta looss, 1902 (digenea: haploporidae) and its proposed synonymy with d. perpusilla looss, 1902. | dicrogaster contracta and d. perpusilla were originally described about 100 years ago from the thicklip grey mullet chelon labrosus. subsequent studies have reported d. contracta in several mullet species in the mediterranean, azov and caspian seas, but d. perpusilla has never been reported again. since previous evidence suggests that the distinguishing features between these two species are uncertain, this study provides new and additional data on the variability of morphometric and meristic ch ... | 2003 | 12815213 |
