This species and  M. williamsiare very similar in hemelytral appearance, both having stripes along the costal region of hemelytra and small groups of short bristles distributed throughout mesotrochanter. Specimens of  M. gonostylahave an enlarged and dark single stripe extending onto the costal margin of hemelytra ( Figure 8A,B), whereas in  M. williamsithe hemelytra bear two stripes ( Figure 9A). Another useful character for separation lies in the outer lateral margin of male mesotrochanters, which on  M. gonostylabears three or more small groups of short bristles ( Figure 8C).    Martarega gonostylamacropterous forms present brown hemelytra with hyaline stripes, resembling those stripe shapes of macropterous form of  M. uruguayensis. Its males may be readily differentiated from other male members of  M. gonostylaby the presence of only one group of short bristles on the ventral surface of their mesotrochanters ( Figure 10D). Rather than possessing an emargination at the base of the hind femora as seen in  M. uruguayensis, female specimens of  M. gonostylabear instead hind femora with continuous margins.  Material examined  Brazil, State of Amazonas, Barcelos Municipality, Serra do Aracá, IgarapéCobra, camp, 136 ma.s.l.
