The biology of Trypanosoma phaleri n. sp. from bowfin, Amia calva L., in Canada and the United States.
Trypanosoma phaleri sp. nov. occurring in the blood of bowfin fishes (Amia calva) from Lakes Erie (type locality), Ontario and Huron, Ontario, Canada, and Suggs Lake, Florida, USA, is described and figured. Between 1985 and 1989, one hundred and thirty three of 136 (98%) bowfin obtained from these sites were infected. T. phaleri is pleomorphic and may be distinguished from related species by comparative morphometrics. The new species developed to infective metatrypanosomes in Desserobdella phalera, and was transmitted by this leech to laboratory-reared bowfin, but not to Catastomus commersoni, Anguilla rostrata, Ictalurus nebulosus, Gasterosteus aculeatus, Salmo gairdneri, Perca flavescens, Stizostedion vitreum, or Carassius auratus. T. phaleri developed poorly in the leech Hemiclepsis marginata.
