Prophalangopsis

Prophalangopsis is a South Asian insect genus, in the family Prophalangopsidae, related to katydids. There is one species: Prophalangopsis obscura, which is a winged insect species found in North India and the Tibetan Plateau. It is one of only a few surviving species in the family Prophalangopsidae. F. Walker described it in 1869 from a single male specimen from India. Liu et al collected two possible female specimens in 2009.

Bioacoustic modeling
In 2022, researchers attempted to recreate the call that P. obscura would make with its legs by using 3D scanning, microscopy, and a Laser Doppler vibrometer.
