Distribution: North America ( Gordon 1976, 1985). Confirmed record for Mexico.

Biology: This species has been collected between the altitudes of 300 and 1,930 m.

Discussion: In the bachelor’s degree thesis of García-Coapio (2005), S. huachuca was reported from Michoacán. However, the tegmen illustrated was actually that of S. ignarus (see discussion for S. huachuca ). The specimen cited in the Material Examined section above confirms that S. ignarus occurs in Michoacán.
