About Rubellia nigro-signata Stål, 1875
Rubellia is a genus of grasshoppers, which was described by Carl Stål in 1875. This genus belongs to the tribe Sphenariini and the monotypic subtribe Rubelliina. The genus appears to be monotypic, meaning it contains only one species: Rubellia nigrosignata (Stål, 1875). This species is endemic to the island of Madagascar.
