the additional species were usually considered a group of the genus "aemilia", but this was long realized to be awkward and possibly wrong. since then, a variety of data has been found to suggest the red-banded aemilia (""aemilia" ambigua") and its closest relatives correctly belong in "pseudohemihyalea". however, the genus is still in need of definite revision, as at least one species is incorrectly placed here.
