Linsley (1964) used the reddish brown coloration of the legs, antennae, and the elytral humeri to distinguish P. infuscatus from P. lecontei (= P. grandis ), to which it is most similar. While this character is useful in separating some specimens, it is present in only about one-half of the material examined, and should, therefore, be used with caution. More salient diagnostic characters include the coarsely alveolate-punctate pronotum and the rugose elytra with very short, dark, appressed setae. In P. grandis , the pronotum is granulate-punctate and the elytra are minutely punctate with longer, erect setae among shorter, appressed setae. In addition, P. infuscatus is generally larger than P. grandis , and is the largest native North American Phymatodes .

Specimens examined: 59, including the type of P. infuscatus
