Eriococcus Targioni Tozzetti 1868: 726.

Type species: Coccus buxi Boyer de Fonscolombe 1834: 218.

Based on evidence provided by Cook and Gullan (2004), all South American species (with the exception of Eriococcus dombeyae González; see below) previously assigned to Eriococcus are either here transferred to Acanthococcus or have been placed previously in Acanthococcus or other genera by Miller and Gimpel (2000) or Kozár & Konczné Benedicty (2008). Because there may be confusion about the current placement of South American species of eriococcids, we have included a checklist of the genera and species in South America (see Appendix 1) and have listed all of the species previously placed in Eriococcus with their current generic designation. We suspect that many of these placements will change in the near future. We do not believe that the genus Eriococcus occurs in South America, even though E. dombeyae currently is placed in this genus. Thus, we are not including a description of the genus nor is it included in the generic key to adult females. González (2008a) gives a detailed description of E. domeyae and a key for the separation of the adult females of species then included in Eriococcus from Argentina.
