Hodgson, C.J., & Henderson, R.C. 1996 A review of the Eriochiton spinosus (Maskell) species-complex (Eriococcidae: Coccidae), including a phylogenetic analysis of its relationships.. Journal of the Royal Society of New Zealand 26: 143-204.

Notes: In addition to E. spinosus, about whose status there is still some uncertainty, the complex contains E. armatus and five new species: E. brittini, E. deboerae, E. dracophylli, E. dugdalei and E. pseudohispidus; descriptions, illustrations and diagnostic keys provided for most scale-like stages of all seven species; importance of the immature stages in scale insect taxonomy and the narrow host range of most species in this tribe.
