Psinidia amplicornis, known generally as the Caudell's longhorn grasshopper or Texas longhorn grasshopper, is a species of band-winged grasshopper in the family Acrididae.

[1][3] The species is found predominantly in eastern Texas, USA[4] replacing P. fenestralis west of Louisiana.

[5] Where the species meets P. fenestralis there may be some hybridisation and introgression and the species can therefore be hard identify in this area.

[5] They are also reported in the very north of Mexico, below the species distribution in Texas.
