Abstract
Surveying 59 references concerning the occurrence of the monogeneans of the family
Diplozoidae parasitizing fishes of Iraq showed the occurrence of 15 valid species of this family
which included one species of Diplozoon, one species of Eudiplozoon and 13 species of
Paradiplozoon. In addition to these species, some unidentified adult and larval (diporpa larvae)
specimens of the genus Diplozoon were reported from 12 fish hosts among which four fish
species showed no infection with any of the nominated diplozoid species while the others
showed mixed diplozoid infections. These diplozoids were reported from 27 fish host species
in Iraq. All the diplozoids were recorded from freshwater habitats except one Dipolzoon sp.
which was recorded from a marine habitat. Hosts recorded for each of these diplozoids ranged
from a minimum of one host in case of both P. ergensi and P. tadzhikistanicum to a maximum
of 13 hosts in case of P. kasimii. Among the infected fishes, 13 hosts harbored only one
diplozoid species each while a maximum of 10 diplozoid species were reported from both
Leuciscus vorax and Cyprinion macrostomum
