| quadriacanthus species (monogenea: dactylogyridae) from catfishes (teleostei: siluriformes) in eastern africa: new species, new records and first insights into interspecific genetic relationships. | african catfishes of the families bagridae and clariidae are known to be parasitized with monogeneans of quadriacanthus paperna, 1961 (dactylogyridae). the genus remains taxonomically challenging due to its speciose nature and relatively wide host range representing two fish orders, i.e. siluriformes and osteoglossiformes, in africa and asia. here, we investigated diversity of quadriacanthus spp. parasitizing clarias gariepinus (burchell), heterobranchus bidorsalis geoffroy saint-hilaire, and ba ... | 2017 | 28764736 |
