Labium is a primitive transantarctic genus which parasitizes ground-nesting halictid bees and until now has been known only from the Australian Region. Diagnostic features include its large exposed labrum (as long as clypeus) ; elongate mandible with upper tooth much shorter and smaller than lower tooth; slender 1st gastric tergite with spiracle distad of middle; and short, concealed ovipositor which is slender, depressed, and without notch or nodus. Labium wahli is now described from south Brazilian rain forest. It differs from the Australian species by its longer flagellum which is only slightly thickened apicad and because it has no crests at base of the notauli
Descriptions are given of the new species Anacis ignifera and A. flammigera from Mérida State, Venezuela and of A. umbrifera from Machu Picchu, Perú. These belong to a tropical Andean lineage with strongly projecting propodeal cristae and pictured wings. Anacis hercana Porter, a Chilean species long known only from the holotype taken at El Canelo near Santiago, now is documented by a second specimen from nearby Río Clarillo. Biconus Townes (1969) is synonymized under Anacis Porter (1967a). Anacis apoeca (Porter), A. atrorubra (Townes), and A. subflava (Porter) are new combinations in Anacis. The South American species of Anacis are keyed.
