Williams, M.L., Hodgson, C.J., & Danzig, E.M. 2002 A new genus and new species of Coccidae from Central America (Homoptera: Coccinea).. Zoosystematica Rossica 11(1): 111-126.

Notes: A new genus of soft scale, Prionococcus Williams, Hodgson & Danzig, is introduced to take two new species, P. agave Williams, Hodgson & Danzig and P. americanus Williams, Hodgson & Danzig from Central America. The adult females of both are described, as are the first instar and second instar male and female and pupa of the latter species. P. americanus has been intercepted several times in the US on imported plants. The new genus is considered to belong to the Coccidae tribe Coccini, and a key is provided to separate it from other genera in this tribe.
