Metacercaria of Alloglossidium corti (Digenea: Macroderoididae) from 3 Species of Crayfish (Decapoda: Cambaridae) in Arkansas and Oklahoma, U.S.A.

摘要

In total, 80 crayfishes, including 25 Orconectes acares, 8 Orconectes palmeri longimanus, 13 Orconectes meeki meeki, 2 Orconectes neglectus neglectus, 21 Orconectes ozarkae, 4 Orconectes williamsi, 4 Procambarus liberorum, and 3 Procambarus tennis, were collected from several counties in Arkansas and LeFlore County, Oklahoma (P. tennis only), and specimens were examined for antennal gland parasites. Three (3.8%) were found to harbor metacercariae of Alloglossidium corti (Lamont, 1921) Van Cleave and Mueller, 1932, including 1 (4%) 0. acares, 1 (12.5%) O. p. longimanus, and 1 (67%) P. tennis. We report 3 new host records for A. corti and the first report of any helminth in these crustacean hosts.
