Comments. Nemorimyza maculosa is easily differentiated from the other species in this genus by the dark spot on the halter (completely yellow in N. posticata (Meigen) and predominantly black in N. ranchograndensis (Spencer)) , the whitish squamae and fringe (blackish in N. ranchograndensis ), the abdomen blackish (partially yellow in N.posticata ) and the curved tubules of the distiphallus (parallel in N. posticata and N. ranchograndensis ). This species has been associated with more than 20 genera of host-plants belonging to the Asteraceae family (Benavent- Corai et al. 2005), forming blotches on the surface of the leaf.
