Eriococcidae, Cockerell, 1899

Hodgson, C. J., Millar, I. M. & Gullan, P. J., 2011, Cissococcus Cockerell (Hemiptera: Coccoidea: Coccidae), a unique gall-inducing soft scale genus on Vitaceae from South Africa, with description of a new species, Zootaxa 2996 (1), pp. 1-32 : 25

Key to separate adult males of Eriococcidae from Coccidae :

1. Scutum without a distinct quadrate membranous area between scutum and scutellum, although some areas of scutum may be membranous; ocular sclerite and genae without polygonal reticulations (although micro-ridges generally present around simple eyes)..................................................................................... Eriococcidae

- Scutum with a distinct, quadrate membranous area between prescutum and scutellum, with lateral margins generally demarcated by a narrow sclerotised ridge; ocular sclerite and genae with polygonal reticulations (though sometimes modified).................................................................................................. Coccidae

On the basis of these characters, it is clear that the adult male of Cissococcus is referable to the Coccidae . The only other family sharing these coccid character states is Aclerdidae , and the males of the Aclerdidae have many features not shared by the Coccidae (Hodgson, unpublished data).
