This species has not been studied by the present authors. It is very similar in structure to C. falsus, apparently differing in having the submarginal line of sculpture on the sternites more strongly formed.
Nakahara & Foottit (2012) provide a key to17 species of Chirothrips from North America, and as a result of that work there are now 46 species worldwide listed in this genus. The key to species provided by zur Strassen (1960) treated the genus in a broad sense, whereas Bhatti (1990) created six new genera for these species, including Arorathrips for several species from theNew World that have the mesothoracic endofurca reduced. C. patruelis is closely related to the widespread species, C. falsus.
