The Kole wetlands of Kerala is a unique wet ecosystem, and yet its insects have not been thoroughly studied. In this paper, a generic level key for the identification of pygmy grasshoppers in the region is provided.

Lepocranus and Valalyllum gen. nov. (Orthoptera, Tetrigidae, Cladonotinae), endangered Malagasy dead-leaf-like grasshoppers Only two leaf-like pygmy grasshopper species and specimens are known from Madagascar: the Leatherback Pygmy Grasshopper (Lepocranus fuscus Devriese, 1991) —which has a relatively low median carina of the pronotum; and the Malagasy Litterhopper (Valalyllum folium gen. et. sp. nov.), herein described — which has a high median carina. Lepocranus fuscus is known from the rainforests around Tampolo, Manakambahiny, and Mahavelona (Foulpointe). The new taxon, Valalyllum folium gen. et. sp. nov. is known only from the Belanono forest. Both species inhabit northeastern Madagascar. The new species could be rare or not-easy-to-spot in the rainforest leaf litter, where it most probably lives. A new tribe, Valalyllini trib. nov., is described for the two mentioned genera because its members are different from the Caribbean leaf-like Choriphyllini Cadena-Castañeda & Silva, 2019, from the African leaf-like Xerophyllini Günther, 1979, and from the Asian leaf-like Cladonotini Bolívar, 1887. A tabular key to the tribes of Cladonotinae with leaf-like representatives is provided, together with photographs of type specimens of both species belonging to the newly described tribe. The holotype of the new species belongs to the Muséum national d’Histoire naturelle Orthoptera collection, Paris.

Valalyllum folium is a new genus and species from Madagascar. It belongs to a newly described tribe Valalyllini together with Lepocranus fuscus. Both species inhabit the rainforest which is suffering severe deforestation.

The results of two years' worth of our Orthoptera fieldwork has just been published. There are more than 100 species in this relatively small area of Dinarides!

Central America is a treasure trove of Tetrigidae, but you would be hard-pressed to find which species live there. In our newest publication, we have fixed this injustice.

Thanks to the Queensland Museum, we got an incredible opportunity to study tetrigids collected from Fiji. We identified a baffling diversity and described many new taxa: 2 tribes, 4 genera, and 7 species. The showcases of the new species are upcoming.
