Chirothrips

Belongs within: Thripidae.

Chirothrips is a cosmopolitan genus of thrips whose members are all found living in grass flowers. Each individual thrips develops within a single floret on the grass’s flower-stalk, and individuals within a species may vary in size depending on the nutritional quality of the host floret (Mound & Marullo 1996).

Characters (from Mound & Marullo 1996): Pronotum trapezoidal, posterior margin at least 1.5 times as wide as anterior margin; sense cones on antennal segments III–IV simple, not forked; antennal segment II usually strongly asymmetric, external margin often produced into a point; mesofurca well-developed, T-shaped, invaginated medially and with paired lateral flanges or, if mesofurca reduced, then metanotum and ventral surface of head with numerous short stout setae.
