![A typical Tetrigid species that commonly inhabits arid banks of water bodies in Southern Africa. Lateral aspect, showing how the pronotum covers the hind wings. The vestigial tegmen is visible just above the anterior coxa.](/Images/godic/202502/05/Tetrigidae_Lateral_aspect_2012_01_28_14292713.JPG")
![Tetrigidae Dorsal aspect. The same specimen from above. In both pictures note the unusually heavy structure of the posterior femur, and the correspondingly massive pulley-like femoro-tibial joint, similar to the anatomy of the Tridactylidae.](/Images/godic/202502/05/Tetrigidae_Dorsal_aspect_2012_01_28_14272713.jpg")
