“…The parasitic copepod family Ergasilidae von Nordmann 1832 in the order Poecilostomatoida (Ho et al 1992) is now considered subordinate to the order Cyclopoida (Boxshall and Halsey 2004). To date, 24 valid genera have been reported (Amado et al 1995), and most of them are freshwater inhabited (Abdelhalim et al 1993).…”

The phylogenetic relationships among the Ergasilidae genera are poorly understood. In this study, 14 species from four genera in the Ergasilidae including Sinergasilus, Ergasilus, Pseudergasilus, and Paraergasilus were collected in China, and their phylogenetic relationships were examined using neighbor-joining, maximum parsimony, maximum likelihood, and Bayesian inference methods based on partial sequences of 18S and 28S ribosomal deoxyribonucleic acid, respectively. All the analyses suggest that the Sinergasilus and Paraergasilus are both monophyletic, but the Ergasilus is polyphyletic rather than monophyletic. Considering the relationships among the four genera, the phylogenetic analyses and subsequent hypothesis tests all suggest that Pseudergasilus clustered with some Ergasilus species may have a closer relationship with Sinergasilus rather than with Paraergasilus. It is proposed that the Sinergasilus and the Pseudergasilus species might have evolved from Ergasilus species.

“…Since this species was recently thoroughly described by Ho et al (1992) from India, and our specimens from Iraq fit well with their description, no additional information is necessary. In India, it is known from another species of mullet, Liza tade, from the coastal zone.…”

“…Half are just like P. inflatus in lacking a pair of postero-lateral protrusions (in the form of hooks or stylets) on the cephalosome. Three of those similar species (P. acanthopagri Roubal, 1981; P. dentatus Ho, Jayarajan & Radhakrishnan, 1992;and P. remulus Cressey, 1970) can be easily distinguished from the present species in having a normal (uninflated) endopod on leg 1. The other three species are P. lagoonaris Paperna, 1969, P. minutus (Fryer, 1956) and P. reductus Ranga Reddy & Kasaiah, 1994.…”

“…The salinity of the Shatt A1-Arab River in the vicinity of Basrah is usually around 1%o; but, a few years ago, it rose to 7%o. Thus, with the entrance of estuarine and even marine fishes from the Arabian Gulf to the Shatt A1-Arab River for feeding and spawning, it is not surprising to find some typical estuarine ergasilids, such as Dermoergasilus varicoleus Ho, Jayarajan & Radhakrishnan, 1992 …”
