Comparison. Massaium gen. nov. is closely related to Atlasacris and Arostratum ; all three genera share the characteristic of having the posterior part of the lateral lobes of the pronotum inflated. Massaium gen. nov. differs from Atlasacris in lacking a long apical spur on the mid tibiae, a conspicuous feature in males of Atlasacris .Although both genera possess short tegmina, they can be distinguished by the coloration of the area between the costal and subcostal margins: in Atlasacris it is white, while in the new genus, only the apex of the tegmina is whitish. In addition, the hind wings in Massaium gen. nov. protrude beyond the middle of the tegmina, a condition not observed in other genera of the tribe. Another distinguishing feature is the male terminalia: in Atlasacris , the posterior margin of the last male tergite bears laterally angled prolongations, which are absent in Massaium gen. nov. Massaium gen. nov. and Arostratum both possess short tegmina and lack a long apical spur on the mid tibiae. However, they differ in the shape of the pronotal lateral lobes: in Arostratum , these lobes are less inflated, and the posterior margin of the lateral lobe is obliquely curved forward. In contrast, Massaium gen. nov. exhibits more inflated lateral lobes, with the posterior margin curved downward. Regarding wing characters, the two genera differ in the stridulatory file and hind wings. In Arostratum , the last tooth on the posterior edge of the stridulatory file of the left tegmen is hook-shaped, and the hind wings are reduced to minute scales. In contrast, in Massaium gen. nov. , the last tooth of the stridulatory file is unmodified, and the hind wings protrude at the middle of the tegmina.
