Based on a single female without indication of origin, this species fell into an obscurity that was a credit to its Apoecilus cynicus (Say) name. The type specimen was apparently not restudied by a pentatomid specialist until Thomas found it in the Thomas (1992: 25) elevated Apoecilus from British Museum collection and recognized the species as subgeneric to generic rank, in the process incidentally that described much later as P. fretus (Olsen, 1916) from removing the generic name Apateticus from the local specimens taken in Massachusetts.

Recently acquired material originated in British Columbia, and southward to North Carolina and Augusta, Bath, Botetourt, Dickenson, Floyd, Giles, Utah.
