Systematics: Slide-mounted adult female with: enlarged setae conical, sides convex or slightly concave basally, apices acute, setae all of approximately same size, abundant over surface; large ducts other than macroducts present in marginal areas of head, thorax and abdomen, surrounded by small cluster of enlarged setae, usually with similar ducts in medial areas of body; anal lobes strongly sclerotized; membraneous plate present on dorsum anterior of anal ring; microtubular ducts elongate with 1 sclerotized area; orifice bifurcate (Williams, 1985h).
Structure: Adult female broadly oval, 2.3 mm long, 1.3 mm. wide, not nodulose. Anal lobes about twice as long as wide, conical, each lobe with apical setae 180 ìm long. Dorsally with an outer enlarged seta situated submarginally rather than on edge, and 2 inner enlarged setae; ventrally with a single slender seta and a suranal seta shorter than anal ring setae. (Kozár, et al., 2013)
Biology: Eriococcus williamsi was originally confused with E. buxi since they both attacked Buxus sempervirens. E. williamsi is a more eastern species (Danzig, 1987).
