The records for this species are from tblMain and are in agreement with the original dot map and the computer generated map, except for one anomoly. In tblMain, there are two entries for California with localities given but no listed counties. In one entry, the locality is San Ysidro, which is in San Diego County, a redundant record. The other locality is Santa Paula, which is in Ventura County, a record not otherwise listed in tblMain. Because this county was not on the original dot map or the computer-generated map, it was not included in the above distribution map. [tmy 9 April 2025]
