Comments. This was the only one species of Scaphisoma with maculated elytra previously cited from Mexico. Matthews (1888) described this species based on specimens from Jalapa (Veracruz) and Cerro de Plumas (Oaxaca). Scaphisoma balteatum can be recognized by uniform reddish coloration of pronotum, elytra orange with a black transversal band. Other diagnostic characters are parallel mesocoxal lines, sinuate metacoxal lines; elytra with sutural stria extended from apex to base, without basal stria; aedeagus ( Figs. 4 View FIGURE 4 m–o) with median lobe symmetrical, apically pointed; parameres basally wider, with apex slightly curved toward inner area; internal sac with a portion of flagellum slightly coiled at the base of the median lobe. All characters of the specimens examined agree with the original description and illustration of S. balteatum ( Mattews, 1888) . This species is recorded for the first time from Costa Rica and Jalisco, Mexico.
