Hainokisaruzo fulvus is characterized by a stouter rostrum, narrow black scales covering the elytra, three white bands of elliptical scales, large apical mucrones on the middle and hind tibiae in the male, shallowly concave pygidia in both sexes, a large, deep, transverse, kidney-shaped concavity on the male ventrite V, a slender spiculum gastrale that is bent rightward in dorsal view and an aedeagal body that is gradually constricted and bluntly projected toward the apex.
