Abstract

Metacestodes of 14 different trypanorhynch larvae were found infesting Arabian Gulf economically important fish along the coasts of the United Arab Emirates. Except for Gri//olia and Plerobolhrium, all other larvae were recorded and described for the first time. The metacestodes were identified as : Callitetrarhynchus gracilis, C. speciosus, Grillolia sp., Nybelini 'a bisulcala, N. indica, N. lingualis. N. sp., Otobothrium dipsacum, O. sp., Progrillolia sp., Pseudogrillotia spratti, Pterobolhrium heleracanlhum, Pterobolhrioides sp. and Tentacularia coryphaenae. Two of them, Callitetrarhynchus gracillis and Pterobolhriuni heteracanthum were very common and have a conspicuously high prevalence rate. The potentiality to invade flesh of fishes was only recorded in two larvae. Pseudogrillolia sprolli and Pterobothrium heterocanthum. All fish hosts are new records.
