Dasineura Rondani, 1840

Diagnosis. Dasineura is a large, cosmopolitan genus of Lasiopteridi and is distinguished from other genera of gall midges by the following combination of characters: The antennae have an uneven number of flagellomeres within a species, not restricted to 12; male flagellomeres have a single basal node and distinct apical neck, while those of the female have almost no neck beyond the node; the costal wing vein is broken just posteriad of its juncture with the R5 vein, which terminates anterior to the wing apex; the tarsal claws are robust, curved beyond midlength, and have a basal tooth; the empodia are approximately as long as the tarsal claws and the pulvilli are about 1/3 the length of the claws; the gonocoxite has a mediobasal lobe that is closely juxtaposed to the side of the aedeagus; the female eighth tergite is longitudinally divided into two sclerites; the ovipositor is elongate-protrusible and its cerci are fused to form a single lobe. Larvae are generally uniform morphologically, with a full basic cecidomyiine complement of papillae and cloveshaped spatula ( Gagné et al. 2014).
