TAXONOMIC AND BIOLOGICAL OBSERVATIONS ON STREPTOCARA CALIFORNICA (GEDOELST, 1919) GEDOELST AND LIÉGEOIS, 1922 AND THE GENUS STREPTOCARA (NEMATODA: ACUARIIDAE)
A detailed redescription is presented for adults of Streptocara californica (Gedoelst, 1919) Gedoelst and Liégeois, 1922 based on specimens from under the gizzard lining of a common scoter, Oidemia nigra (L.), from Vancouver, Canada. Adult S. californica are here reported from the type host, Melanit...
