Summary
A new large-tailed echinostome cercaria with 22 collar spines and 36 flame cells in all has been experimentally connected with Stephanoprora denticulata. Chickens serve as suitable definitive laboratory hosts wheras Actitis macularia is the natural definitive host. Freshwater fish, Lebistes reticulatus, are the second intermediate hosts. The synonymy of the species has been discussed and there is a proposal for the rejection of the genus Beaverostomum. There is also a key for the separation of the large-tailed echinostome cercariae.
Zusammenfassung
Eine neue breitschwänzige echinostome Cercarie mit 22 Kragenstacheln und insgesamt 36 Wimperflammenzellen stellte sich experimentell als zu Stephanoprora denticulata gehörig heraus. Küken dienen als geeignete Endwirte, während Actitis macularia der natürliche Endwirt ist. Süßwasserfische der Art Lebistes reticulatus sind die 2. Zwischenwirte. Die Synonymie der Art wird diskutiert, und es wird ein Vorschlag für die Verwerfung des Genus Beaverostomum gemacht. Außerdem wird ein Bestimmungsschlüssel für die breitschwänzigen echinostomen Cercarien gegeben.
