Systematics: Slide-mounted adult female with: enlarged setae broadly conical, with slightly rounded apices, marginal setae slightly larger than other dorsal setae, noticeable bare area in medial area of abdomen, 2 large-sized setae on lateral margin of each abdominal segment (Hoy, 1963). It is morphologically closest to Eriococcus pallidus Maskell, but that species has more elongate dorsal setae and anal lobes, and is much larger (length 1.70 mm). (Henderson, 2006)
Structure: Description based on 1 specimen so details are lacking (Hoy, 1962). Diagnostic features are the combination of small size (length approx. 1.0 mm), shape of anal lobes (approximately triangular), and distribution of enlarged dorsal setae in rows. (Henderson, 2006)
Biology: Occurs in galls on the leaf of the host (Hoy, 1962).
General Remarks: Detailed description and illustration by Hoy (1962). Because Brittin's slide labels mixed up the adult and intermediate (2nd-instar) females, Hoy mistakenly described a very poor specimen, a parasitised 2nd-instar female, and designated it holotype, stating that it was the only adult female available. E. elytranthae is described in Henderson (2006) from the two paratype females to redress that problem.
