Abstract

Pygidiopsoides spindalis Martin 1951 is reported from the gills of a new second intermediate host, Gillichthys mirabilis Cooper 1864 (the longjaw mudsucker), collected at Point Mugu Lagoon, (Naval Air Weapons Station), Point Mugu, California. Ascocotyle (Phagicola) diminuta Stunkard and Haviland 1924 were also found. Metacercariae were enzymatically excysted from gills and ex- amined by scanning electron microscopy. Fundulus parvipinnis Girard were ex- amined and yielded P. spindalis and Ascocotyle sexidigita Martin and Steele 1970. Parasites reported from the longjaw mudsucker were reviewed. The presence of these trematodes in spite of heavy contamination may be indicative of the health of the Mugu lagoon ecosystem.
