Comments.

This is the first collection of Oxypoda rubescans since its description based on a male specimen collected in the Catskill Mountains of New York ( Casey 1911). The aedeagus of this species is illustrated for the first time (Fig. 90). This species is similar in habitus to Oxypoda hiemalis Casey but is immediately differentiated by the elytra, which are longer than the pronotum at suture. Oxypoda rubescans may be easily recognized by the distinctively shaped median lobe of the aedeagus in lateral view (Fig. 90). To promote nomenclatural stability, we designate a lectotype for this species here.
