Comments: The
species listed above have traditionally been treated as members of the genus
Acrosternum. True species of the genus Acrosternum, however,
are smaller, pale green in color, and live in dry, arid regions of the Old
World. Members of the genus Chinavia are larger, more deeply and
richly green in color, and live in temperate or tropical area of both the Old
and New Worlds.
