Systematics: It is morphologically closest to Eriococcus kowhai Hoy but that species lacks the papillate anal lobes and medium size tubular ducts, and its marginal setae vary considerably in size. (Henderson, 2006)
Structure: Diagnostic features are the rugose and extremely papillate anal lobes, body without a nodulose dorsal derm, uniform size and distribution of enlarged marginal setae, and 3 types of tubular ducts. (Henderson, 2006)
Biology: Settled 1st-instar nymphs yellow, inducing small depressions on underside surface of leaves. Second-instar nymphs inhabiting open pit galls on stems, either at nodes or between nodes, with stem swollen around each gall. Female nymphs develop to adult on stems before migrating back to leaves. Male nymphs apparently migrate back to leaves at end of 2nd-instar feeding stage. Mature adult females on underside of leaves, apparently cease feeding as there are no associated leaf deformations present; these females pale green when starting to form their ovisac; older females dark green beneath a large white fluffy ovisac, producing white eggs. (Henderson, 2006)
General Remarks: Good description and illustrations in Henderson (2006)
