Subgenus Elmomyza

Diagnosis. Species placed in this subgenus may be recognized by head usually square-shaped in lateral view and arista usually with two dorsal and no ventral branches, sometimes lacking the terminal fork. Thorax bears only one postpronotal seta, and two to six rows of acrostichal setae between the anterior dorsocentrals. Male terminalia presents broad epandrium, often possessing strong ventral lobes; cerci well-developed and, although usually without modifications, may exhibit a ventral lobe that ranges from small to longer than the cerci itself in some taxa; surstylus with a strongly concave ventral lobe; surstylar teeth along at least part of the inner margin. Female terminalia presents oviscapt, usually with weakly sclerotized valves, and no ovisensilla ( Hackman 1959, 1962; Hardy 1965, 1966; Hackman 1982).
