Based on DNA, California population may represent a distinct species. See Kruse & Powell 2014. As of 11/14/2015, BOLD shows two BIN clusters for this species north of Mexico:
BOLD:ABY9168 contains specimens from US and Canada east of the Rockies and
BOLD:ABZ6564 contains specimens from CA, AZ, CO, TX, OK, FL, SK, and southern Central America. These two BINS are not each other's closest neighbor. A third BIN,
BOLD:AAA1117, from Central America appears to be intermediate between the two proceeding BINs.
Kruse & Powell 2014 mention subtle differences is wing pattern which tend to separate
C. penetralis from
C. peritana, however, the distinction does not seem to apply with respect to the California population on
C. peritana. Compare
BOLD:ABZ6564 (California
C. peritana) and
BOLD:AAA5258 (
C. penetralis).
