the genus was long included in "hemihyalea" when the latter was still unresolved versus "amastus", but seems to be distinct and in fact contain more species than originally believed. the initial confusion stems partly from the fact that régo barros when describing the genus set the type species to be "phaegoptera rhoda", but he had actually misidentified "pseudohemihyalea schausi" specimens as "p. rhoda".
