Other Specimens. In the 178 specimens of this species in BOLD, there are records from San Diego County, and the species is common in BioSCAN samples from the Los Angeles area.

Diagnosis. In addition to barcode data, we determined that the wing venation of this species is slightly different than that of the sympatric M. sulphurizona , with a short, slightly more arched subcosta ( Fig. 32 ). Furthermore, wing vein landmarking establishes a clear difference between these two species ( Fig. 2 ). The most similar CO1 barcodes are found in M. tropizona , which differs by a minimum p-distance of 1.56% ( Fig. 1 , Table 1). The wings of M. tropizona and M. cryptizona are well-distinguished by wing vein morphometrics ( Fig. 31 ).

This species is in BOLD as BOLD:ACN6913.

Distribution. Southern California, USA.

Etymology. The name is based on Latin for hidden (crypt), referring to the unexpected discovery of this species mixed with M. sulphurizona .
