Phryganistria

Phryganistria is a genus of stick insects belonging to the subfamily Clitumninae, native to northeastern South Asia, northern Mainland Southeast Asia, and southern China. The species in this genus range in size from fairly large to very large.

The world's longest stick insect (which also makes it the longest known insects) is a currently undescribed species from Guangxi, China, informally referred to as Phryganistria "chinensis". A wild collected female kept at the Insect Museum of West China was the record holder at 62.4 cm in total length (including extended legs), but it was surpassed by one of its captive bred young that reached 64 cm. The second-largest member of the genus likely is Phryganistria heusii yentuensis, with a total length of up to 52 cm and a body length up to 32 cm. Another, Phryganistria tamdaoensis was selected in 2015 by the International Institute for Species Exploration as one of the "Top 10 New Species" for new species discovered in 2014.
