The North American fauna is represented by 33 species (about 4.5 % of the world fauna), of which two are adventive. Taxonomic Note. Jeannel (1949a: 991) grouped this subtribe and the demetriadines under the subfamily Dromiitae and stated that this complex is characterized by having the basal bulb of the median lobe reduced. The peliocypidines were included in this subtribe by Ball and Bousquet (2000: 112).
