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