RECOGNITION.— Adults of this species can be distinguished from those of other species of Pseudonomaretus by the following combination of character states: SBL = 13.0 mm or more (males 16.4–16. 7 mm, females 17.7–18. 3 mm); elytra moderately dull, microsculpture distinctly impressed, without metallic reflection; head with a more or less distinct transverse impression at level of posterior margin of eyes clearly delineating frontal and occipital regions; labrum ( Fig. 2e) with lateral lobes markedly long and narrow; antennomere 4 ( Fig. 3e ) not pubescent, with only a very few scattered setae in addition to apical whorl of setae; pronotum with basolateral pair of setiferous pores absent; male protarsomere 1 ( Fig. 7b ) with pad of adhesive setae ventrally over virtually entire ventral surface, protarsomere 4 without a pad; elytra with 13 to 15 regular striae, only the lateral one or two slightly interrupted in some individuals, elytral intervals 4 and 8 each with two to six discal setiferous pores; median lobe of male aedeagus ( Fig. 10) with ventral margin evenly arcuate in lateral aspect ( Fig. 10b), widest at about apical one-third of shaft and gradually and arcuately tapered to a narrowly rounded apex in dorsal aspect ( Fig. 10a).

GEOGRAPHICAL DISTRIBUTION.— This species is known only from a few localities in southeastern Washington and northeast Oregon ( Bergdahl 2014)
