Synonyms and other taxonomic changes
First described in 1930 by Douglas Melin as Phymata erosa americana.
Four subspecies in the United States (americana, coloradensis, metcalfi, and obscura)(1).
7.5-12 mm
Easiest to separate by the undilated connexival segments which form a more or less smooth margin. This feature is more conspicuous in the males.

In the eastern states, the lack of an ultraconnexivum on the fourth segment and the large size (7-12 mm) leave only P. americana, P. fasciata, and P. pennsylvanica. From the latter two, the undilated margin will separate P. americana. All of these species also occur in the western states.

Among the larger species in the West, it is more difficult to separate from P. borica, P. salicis, and P. pacifica although it is apparently allopatric with respect to the latter.
More or less transcontinentally(1).
