This genus was erected by Rondani in 1840 for certain small 
forms presenting the general appearance of Campylomyza and easily 
distinguished therefrom by the Io or 11 antennal segments of the 
male and the 8 of the female, they being sessile in both sexes; the 
second greatly enlarged, and having a diameter more than twice 
that of the third. The antennal setae of the male are unusually long, 
being three to four times as long as the segment. The palpi are 
quadriarticulate, the first segment rudimentary, the others nearly 
normal, the third in the female greatly expanded apically. Subcosta 
joins the anterior margin near the middle, the third vein before the 
apex and is united to subcosta by a distinct cross vein; the fourth 
vein is simple, indistinct and joins the posterior margin; the fifth
