Diagnosis

1) Longitudinal vein CuP poorly developed in both sexes or absent; 2) membranous filaments of mesoscutellum absent; 3) forceps tri-segmented with first segment, distomedially projecting, 4) penis with very wide base, becoming thinner towards a subapical constriction, and then slightly widening again, penis lobes of each side almost completely fused except apical incision; 5) penis with a ventral projection covered with spines.

As M. australis is the only species for which nymphs have been described, the generic diagnostic features of the nymphal stage should also be used for specific diagnosis.

Distribution ( Fig. 1 )

Argentina (Misiones), Brazil (Amazonas, Espírito Santo, Mato Grosso, Pará, Paraná, Roraima) and Guyana.
