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 .
