Remarks. The complicated search for the actual name of the genus was finalised by the revision of South American genera by Mohrig & Menzel (2014). Most of the species are characterized by the depigmentation of the last 2–3 flagellomeres in one or both sexes. The head is in some species distinctly higher than long (prolonged mouth parts), the scutum has very short and sparse hairs, M1 is generally arched by differing degrees (M-fork in some species vase-like), the posterior wing veins are sometimes with macrotrichia, the membrane between sternites and tergites is mostly darkly pigmented, the fore tibia has a wide Bradysia -like comb, the claws have fine teeth and the gonostylus has an apical tooth and a different number of spines at the base of the tooth or on the inner side of the gonostylus. The genus is known from Central and South America. The report from Australia is within the Sciaridae the first hint of a faunistic exchange through the Gondwanan Bridge and the existence of sister groups in the continents of the southern hemisphere.
