Type species. Macromotettixoides jiuwanshanensis Zheng, Wei & Jiang, 2005

Redescription. Size small and stout. Vertex nearly at the same or slightly below the level of anterior margin of pronotum, and decidedly wider than width of one eye; frontal costa with longitudinal furrow relatively shallow, equal to or wider than diameter of scapus; antennae filiform, situated between or below lower margins of eyes. Pronotum roof-like or nearly at the same level; median carina conspicuous, sometime weakly, but not strongly lamellate; hind process short, not surpassing apex of hind femur, apex acute or acutely rounded; posterior angle of lateral lobe turning outwards, apex truncated or roundly truncated; ventral sinus present, tegminal sinus absent or very inconspicuous; external lateral carina surpassing middle of lower margin of pronotum. Tegmina and alae generally invisible or rarely visible but extremely abbreviated. Female ovipositor narrow and long.

Differential diagnosis. This genus is similar to Macromotettix Günther 1939 , but differs in one concavity (namely ventral sinus) on the hind margin of lateral lobe of pronotum instead of two concavities (namely ventral sinus and tegminal sinus) in Macromotettix ; tegmina being always externally invisible (vestigial, covered by pronotum) but normal in Macromotettix .
