The genus Lasiopleura Becker is peculiar in the family Chloropidae in the unusual development of the chaetotaxy of head and thorax. It is apparently an ancient group, with representatives in all the faunal regions. A number of generic names have been proposed, and a thorough study of the species of the world may show that some of them can be maintained, either as genera or as subgenera, though perhaps on different bases from those on which they were proposed. The group is especially rich in species in Australia and the South Pacific area.
