title: Redescription of Argulus melanostictus (Branchiura: Argulidae), a parasite of California grunion (Leuresthes tenuis: Atherinidae), with notes regarding chemical control of A. melanostictus in a captive host population.
abstract: Adult male and female Argulus melanostictus Wilson, 1935 are redescribed based on detailed examinations of a syntype and recently obtained specimens of both sexes collected from California grunion, Leuresthes tenuis, captured in nearshore Pacific waters at Monterey, California. A 14-16-hr seawater bath containing 0.5 microliter/L trichlorfon administered once weekly for 3 wk killed A. melanostictus while not noticeably harming grunion.
