(Figs. 33 H–J)

Diagnostic remarks. A medium-sized, non-descript green katydid, with hind wings barely surpassing the tegmina (Fig. 33J); the tegmina are distinctly shiny and quite strongly sclerotized, rigid. The male cerci are long and slender (Fig. 33H), incurved when seen from above (Fig. 33I). This species is similar in its overall appearance to Catoptropteryx aurita but can be distinguished by much longer cerci in the male and by fully developed, long and slender ovipositor in the female. The tympana on the front tibia are bilaterally closed.

Distribution and natural history. M. eriki was recently described from Tanzania (Hemp 2017a) and finding it in central Mozambique significantly extends its known range. In Gorongosa this species is uncommon, found only in the canopy of the tall Brachystegia miombo woodland. The call of the Mozambican population is unknown.
