Trematodes of Audouin's gull Larus audouinii (Aves, Laridae), from Chafarinas lslands (W Mediterranean)

Abstract

A survey was carried out on the trematode fauna of Larus audouinii Payraudeau, 1826 (Aves, Laridae) in the Alboran Sea, south-western Mediterranean. A total of 10 trematode species was found: Sch/josomaatinae gen. sp., Ornithobilharzia sp., Pachytrerna calculus, Renicola lari, Brachylecithurn microtesticulaturn, Condylocotyla pilodora, Knipowitschiatrema nicolai, Cardiocephalus longicollis, Acanthotrema armata and Aporchis rnassiliensis. The main morphoanatomic characteristics of helrninths and the ecological host-parasite relationships are presented. L. audouinii becomes a new host for the 10 trematode species.
