Miller, D.R., & Miller, G.L. 1993b A new species of Puto and a preliminary analysis of the phylogenetic position of the Puto group within the Coccoidea (Homoptera: Pseudococcidae).. Jeffersoniana: Contributions from the Virginia Museum of Natural History (4): 1-35.

Notes: Abstract: Three instars of the female and five instars of the male Puto kosztarabi are described and illustrated. This represents the first described species from eastern North America. A checklist of the known species of Puto, keys to the adult male Puto, North American female Puto, and instars to P. kosztarabi are included. A cladistic analysis utilizing 23 taxa and 38 characters supports the monophyly of the Puto group.
