The taxon heretofore known as Tetragastris panamensis is widespread in tropical Central and South America and often common where it occurs. All recent phylogenies for Burseraceae tribe Protieae strongly support submerging Tetragastris as a section of a more inclusive Protium. A recent smorgasbord of nomenclatural changes coined a new name for T. panamensis because the epithet is already occupied in Protium. That is unnecessary, however, because the taxon can be given the next most recent available name from a heterotypic synonym: Protium stevensonii.
