Tribe Dasineurini

"This tribe is a large, heterogeneous assemblage of 870 primary plant feeders. Most cause simple or complex plant galls, but some live freely in flower heads, and some others are inquilines. I place here those Lasiopteridi that share most of the following characteristics (with some exceptions): male flagellomeres with definite necks; wing with R5 joining C at least slightly before the wing apex; a protrusible ovipositor; female eighth abdominal tergite as long or longer than seventh and tending to divide longitudinally; and male genitalia with mediobasal gonocoxite lobes that gradually taper from base to apex and are nearly as long as the aedeagus. None of these characters is unique to this tribe, especially with regard to Camptoneuromyiini and Lasiopterini, which may be offshoots of Dasineurini, but the genera placed here show some general resemblance to one another. Some genera that are unplaced to tribe may also fit here."(1)
