They include E. biannulata Moore (1904), E. kobiensis McIntosh (1885, holotype examined), E. segregata (Chamberlin, 1919a, restricted), E. semisegregata, new species, E. valens (Chamberlin, 1919b, types examined), and E. websteri, new name for E. longicirrata Webster (1884, holotype examined). The relationship between the six species is discussed.
