Remarks

• Systematics: Slide-mounted adult female with: enlarged setae cylindrical, sides straight, apices truncate or rounded, setae of 2 sizes, larger size present on head, smaller size scattered over dorsal surface; anal lobes with 4 large-sized enlarged setae, dorsal surface with multilocular pores, predominant multilocular pore type on venter with 7 loculi; microtubular ducts short, with 2 sclerotized areas (Miller & Miller, 1992). Eriococcus palustris Dodds (1923) is a senior homonym of Eriococcus palustris (Dzeidzicka & Koteja, 1917) which has been given the replacement name E. podhalensis.
• Structure: Adult female is violet gray; eggs, first and second instars cadmium yellow. Ovisac is felted, white, but turns gray when wet with sea water (Dodds, 1923).
• Biology: This species is only known from the high tide level of San Francisco Bay where it may be subject to short periods of submergence. The ovisacs contains an average of 60-70 eggs with as many as 92. First instars apparently overwinter in the ovisac. In the laboratory, the first molt occurs 17 days after hatching. The second mold occurs approximately a week later. The ovisac is produced one day after the second molt. (Dodds, 1923).
• General Remarks: Detailed description, illustration and photographs in Dodds (1923). Miller & Miller (1992) and Ferris (1955a) also provide illustrations and descriptions.
