Systematics: Aulacaspis marina is similar to Aulacaspis vitis, but they are clearly distinguishable in the second-instar male. They differ in the presence (in A. marina) or absence (in A. vitis of modified (cuplike) macroducts in the dorsal submarginal region of the abdomen. The adult females of Aulacaspis marina and A. vitis were distinguished by the relative size of the median trullae [lobes] and the presence or absence of disc pores at the posterior spiracles: in A. marina the median trullae were as broad as the inner lobule of the second trulla, whereas in A. vitis they were usually a little broader than the latter; in A. marina the posterior spiracles were usually accompanied with disc pores, whereas in A. vitis they were always without disc pores. (Takagi & Williams, 1998).
Structure: Female test circular, white, thin, semi-transparent or opaque; exuvial casts marginal. Male test tricarinate (Takagi & Williams, 1998).
Biology: Mean fecundity of Aulacaspis marina is 141 eggs. Generation time of this species is between 34 and 42 days based on 4 generations, suggesting the species has 9 to 10 generations per year on Bali (Ozaki et al., 1999).
Economic Importance: Spraying seawater on hosts can be an effective method of control (Ozaki et al., 2000)as well as ant predation and natural enemies (Ozaki, 2002).
General Remarks: Best description and illustration by Takagi & Williams (1998).
