The story of the Malagasy devils (Orthoptera, Tetrigidae): in the north and sp. nov. in the south?

Madagascar is home to some of the largest and most colorful pygmy grasshoppers (Tetrigidae) in the world, known as 'Malagasy Metrodorinae'. Among them, Devil's pygmy grasshoppers (genus Bolívar, 1887) are unique in having two long spines on the back, which are modified internal lateral pronotal carinae. The genus was composed of two species - (Serville, 1838) and Rehn, 1929 , but here it is evidenced that the latter represents a junior synonym of the former.
