Family Tetrigidae Rambur, 1838

Diversity in Madagascar.

Altogether, 76 Tetrigidae species (including the new one) are known to inhabit Madagascar, of which 73 (= 96%) can be found only in Madagascar and nowhere else in the world (Cigliano et al. 2022). These species are assigned to altogether 29 genera, of which 24 are endemic to the island. Hitherto, only a single leaf-like species was known from the island, Lepocranus fuscus . This study adds one more species with this interesting cryptic morphology, Valalyllum folium gen. et sp. nov.
