It resembles Oriverutus in its general appearance and odontostyle length, but both genera are provisionally distinguishable by the morphology of lip region (lips not lobe-like and perioral area barely differentiated in Dorydorella ) and of female tail (always straight ventrally and up to twice the anal body diameter in Dorydorella ). Nevertheless, further studies should be undertaken to elucidate the relationships between these two genera.
