Related and similar species

The genus Caprithrips includes 6 species, from various parts of the world. They are all wingless grass-lliving species, and a key to these is provided by Bhatti (1980). C. orientalis has 8-segmented antennae, but unlike C. moundi the sternites have broadly lobed craspeda on their posterior margins.
