Thrips of California 2012

Chirothrips secalis

Recognition data

Distinguishing features

This species has not been studied by the present authors. It is apparently readily distinguished from the other members of the genus because the sensorium on antennal segment IV is forked (not simple) and antennal segment II is symmetrical (not produced on the outer margin).

Related and similar species

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 the New World that have the mesothoracic endofurca reduced.
