Diagnosis. The wing of M. danizona is highly distinctive, with a long costa and strongly anteriorly-curved M 1 vein ( Fig. 19 ). The barcode is most similar to that of A. oklizona new species , from which it differs by 6.06% minimum p-distance ( Fig. 1 , Table 1 ). This species is in BOLD as BOLD:ACY0171. Distribution. Costa Rica . Etymology. This species is named for Dan Janzen, whose projects have yielded many new species of insects.
