In this Part, 37 species of the genus, belonging to eight species-groups, are described and figured, and their phylogenetics and biogeography are discussed. Seven of the species are described as new: P. ecuadorae, friburgensis, marthae, onorei, pulawskii, riopretensis, yucatani. One species-name, P. tolteca Lucas, 1895, is recalled from synonymy and one name, P. lycaon Banks, 1945, is upgraded from varietal to species status.

Keys to all forms are given. Lygarochromy and two mimicry-groups are defined and described and the occurrence of large individuals on islands is briefly discussed.
