None. Diagnosis. The barcode of this species differs from that of nearest neighbor M. paulizona from Colombia, by a minimum p-distance of 8. 54% (Fig. 1, Table 1). Wing landmarking separates the few known specimens. The wing is distinctive in this species, with its relatively long costa, 0.46 of wing length versus 0.41 for M. paulizona, as well as the yellowish-brown forecoxa (dark brown in M. paulizona). This species is in BOLD as BOLD:ADH5444. Distribution. Costa Rica. Etymology. Named for Costa Rican Museo Nacional Diptera curator Maricelle Méndez Soto.
