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.

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