The genus typically exhibits a more elongated body form compared to some other Porcellionidae. Specific identification to species level requires examination of male genitalia and detailed pleopod structure. Differentiation from Armadillidium ( Armadillidiidae) is straightforward as Proporcellio cannot conglobate (roll into a ball).
