Comments. Cletus similis Blöte (1935) resembles C. minutus Blöte in its total body length being less than 8.25 mm, the antenniferous tubercles unarmed, the apical edge of corium with an ivory to whitish discoidal spot, and the anterior half of pronotal disk, as well as the mesopleuron, with a small black discoidal spot. C. similis differs in that each antennal segment is conspicuously shorter (see measurements) and in having black to reddish brown spots on the head, the pronotal disk forming a wide stripe that usually reaches the base of the scutellum, and the humeral angles tapering into short subacute spines, directed outward ( Fig. 9 ). In C. minutus the humeral angles are larger, acute, and also directed outward ( Figs. 7, 9 ).
