Parasitic Helminths and Arthropods of the Crested Serpent Eagle Spilornis cheela perplexus Swann, 1922 from the Yaeyama

Abstract

Thirty-eight individuals of the Crested Serpent Eagle, Spilornis cheela perplexus Swann, 1922 collected between 2001 and 2009 from Yaeyama Archipelago, Okinawa, Japan, were investigated. A total of 11 helminth and two arthropod parasites, including seven nematodes (Eucoleus contortus, Baruscapillaria falconis, Aonchotheca caudinflata, Porrocaecum angusticolle, Procyrnea leptoptera, Microtetrameres accipiter and Synhimantus sp.), three trematodes (Basantisia ridwani, Strigea microbursa and Neodiplostomum georgesduboisi), an acanthocephalan (Centrorhynchus spilornae), a chewing louse (Craspedorrhynchus sp.) and a feather mite (Artamacarus sp.), were identified. Among these parasites, E. contortus, B. falconis, A. caudinflata, P. leptoptera, M. accipiter, Synhimantus sp. and Artamacarus sp. were the first host records for S. cheela, and all helminths and arthropods are the first host records from S. c. perplexus. With the exception of E. contortus, all helminths and arthropods were the first local records from the Yaeyama Archipelago.
