Phymatodes maculicollis is similar to P. vilitatis , having an elongate form wherein the elytra are approximately three times as long as the basal width, and clothed in short, pale, subappressed setation. The majority of specimens have the pronotum orange-brown with a darker median macula, however, some specimens have the pronotum entirely dark brown, superficially resembling P. vilitatis . The two species can be further separated by the maxillary palpi. In P. maculicollis the maxillary palpi are two times as long as the labial palpi, and the apical maxillary palpomere is strongly dilated, while in P. vilitatis , the maxillary palpi are only slightly longer than the labial palpi, and the apical palpomere is not dilated. There are some minor differences in the antennae of these species as well; P. maculicollis has longer antennae in general, with the male antennae attaining three-quarters the length of the elytra, while those of P. vilitatis attain only two-thirds. The females of P. vilitatis have the antennae shortened, attaining one-half the length of the elytra, and the apical antennomeres (VII—XI) becoming, smaller, wider, and appear more congested or clubbed. The females of P. maculicollis lack this character. Additionally, both of these species lack a distinct constriction between the upper and lower eye lobes, with the upper lobe and the portion of the eye in the antennal notch being the same width.
