Etymology: Schismatogobius: Greek, schisma, -atos = crack, fissure + latin, gobius = gudgeon (Ref. 45335); vanuatuensis: The name for the new species is derived by combining Vanuatu and the Latin suffix -ensis that in combination means 'from the Vanuatu'. This name is used because the new species is known only from Vanuatu.
