Remarks

• Systematics: This species is closest to Eriococcus myrsinae Hoy, but can be separated by 1) the shape of the anal lobes which are broadly triangular with a distinctly curved dorsal basal margin and with a ratio width to length about 1:1.2; 2) anal lobes more papillate and rugose than on E. myrsinae; 3) possession of a dentible on the claw (absent in E. myrsinae); and 4) a microduct associated with each robust seta (not so associated in E. myrsinae). The adult female of Eriococcus parsonsiae Henderson was described as having papillate and rugose anal lobes, but i that species the lobes are elonhgate and the robust marginal setae on E. parsonsiae are pointed rather than conical, ventral disc pores are numerous, translucent pores are absent from metathoracic femora.
• Structure: The felt cover of the adult female appears resinous and brown, Nymphs have a marginal fringe of quite broad wax filaments. The adult female body shape elongate-oval, derm membranous except for anal lobes, eyespots present. Marginal setae robust, conical with rounded tips. Diagnostic features include the presence of translucent pores on the metacoxae and metafemora; the robust dorsal surface setae forming a longitudinal median band; and minute truncate dorsal setae. 2nd-instar female is elongate-oval, generally smaller than adult female; lacking vulva, macrotubular ducts, and translucent pores on metathoracic legs; anal lobes sclerotised by not strongly papillate. 2nd-instar male similar to 2nd-instar female except for presence of 2 kinds of dorsal tubular ducts and with antennae and various body setae slightly longer, and ventral disc pores more numerous. 1st-instar female nymph is similar to the 2-nd instar female nymph except the shape of rubust marginal setae are more pointed than conical, robust setae absent from Dorsum, microducts and quinquelocular pores much less frequent.
• General Remarks: Detailed description and illustrations of adult female, 1st instar nymphs, 2nd instar male and female in Henderson, et al., 2010.
