Abstract

In this paper we redescribe 16 previously poorly known species of pseudococcids. Their taxonomic status, generic assignments, and relationships to other mealybugs are given. The species treated are: Cataenococcus formicarii (Ehrhorn); C. guatemalensis (Ferris); C. phoradendri (Cockerell); Cryptoripersia arizonensis (Ehrhorn); G. trichura (Cockerell); Dysmicoccus aurantius (Cockerell); D. lasii (Cockerell); D. morrisoni (Hollinger); D. roseotinctus (Cockerell and Cockerell); Puto lasiorum (Cockerell); P. sandini (Washburn); Spilococcus juniperi (Ehrhorn); Tridiscus sporoboli (Cockerell); Trionymus caricis McConnell; T. magnus (Cockerell and Cockerell); and T. violascens Cockerell.

New synonymy is as follows: Cryptoripersia trichura =Trionymus hypolithus Shotwell); Trionymus violascens =T. furvus McKenzie). Dysmicoccus formicarii (Ehrhorn) is transferred to Cataenococcus. Revised keys to the following genera are also presented: Cataenococcus, Cryptoripersia, Dysmicoccus, Spilococcus, Tridiscus, Trionymus.
