A New Species of Gill Monogenea (Dactylogyrus Diesing, 1850) from Hampala macrolepidota van Hasselt and Kuhl 1823 (Cyprinidae) in Sungai Kiang and Tanjung Mentong, Tasik Kenyir Lake: Malaysia

並列摘要


During surveys of gill monogenean parasites in tropical freshwater lake (Kenyir Lake) in Malaysia, one new species of the genus Dactylogyrus Diesing, 1850 was found and described. The study aims at investigating monogenean parasites parasitizing Hampala macrolepidota Van Hasselt and Kuhl 1823 (Cyprinids) in Sungai Kiang and Tanjung Mentong from the Kenyir Lake, Malaysia. In record there were three known species of the genus Dactylogyrus found in this fish host in Malaysia viz: D. hampali, D. macrolepidoti and D. quadribrachiatus and one also known in Thailand: D. anchorobustussumming to four known Dactylogyrus sp. parasitizing Hampala macrolepidota from this region. Taxonomic and morphometric data for this new species was presented. Dactylogyrus terengganusis n. sp. differs from the previously described species at the species level principally by its hamuli, dorsal connective bar, copulatory organ accessory piece and worm size.
