Physoderus [sic] azrael Kirkaldy, 1905: 339 .

Diagnosis

This species is recognized among other species of Physoderes by the head being anteriorly light brown and posteriorly brown, the pronotum dark brown straw-colored or with a light brown humeral tubercle, the posterior margin, parascutellar lobe, scutellar process and base of the corium light brown, the short and conical head, the scape reaching the apex of the clypeus, the anterior pronotal lobe being equal to or slightly narrower than the posterior lobe, the parascutellar lobe being rounded and skewed towards the median, the semicircular scutellum, the spatulate and apically rounded scutellar process, the pronotum flattened in lateral view and the hemelytron reaching the tip of the abdomen. In the male genitalia, the following features are also diagnostic: the extremely narrow transverse bridge of the pygophore and the apically truncate endosomal struts, which are basally divided into two arms converging medially to form basally a ridge. This species is most similar to P. curculionis but can be differentiated by the coloration, elevation of the pronotum, shape of the abdomen and shape of the endosomal struts in males.
