This species has not been studied by the present authors. It is apparently readily distinguished from the other members of the genus because the sense cone on antennal segment IV is forked (not simple) and antennal segment II is symmetrical (not produced on the outer margin).
Currently there are 42 species worldwide placed in the genus Chirothrips, and Nakahara & Foottit (2012) provided an account of the species from the Americas. The genus was treated in a much broader sense by zur Strassen (1960), whereas Bhatti (1990) created six new genera for several species. In particular, Arorathrips was erected for a group of New World species that have the mesothoracic endofurca reduced.
Each larva presumably develops within a single floret of a grass.
Recorded only from California and Wyoming
