Listroscelidinae
Spiny Predatory Katydids
Listroscelidinae is a subfamily of predatory katydids (Tettigoniidae) distributed across the Americas, Madagascar, and Australia. Members are characterized by spiny morphology and predatory habits, with enlarged mandibles adapted for capturing prey. The subfamily contains multiple tribes including Listroscelidini, Terpandrini, Requenini, Hamayulini, and Conocephalomimini. Several genera have been described in recent decades, particularly from the Atlantic Forest biome of Brazil and northern Australia. The genus Arachnoscelis gained public attention after appearing on the cover of Science in 2012.
