Phylloporus alborufus is newly described, and an unnamed species is also described from Costa Rican oak forests. Phylloporus colligatus was recently described from a Dicymbe forest in Guyana. A table of the 24 known New World Phylloporus taxa, their distribution and possible hosts also is presented.
