Halgerda albocristata is characterised by its yellow mantle with numerous intersecting opaque white lines (compared to H. elegans which has a translucent mantle with numerous intersecting, orange-yellow lines). The mantle margin is translucent white with numerous blackish brown lines - usually one long line and then three short ones. The undersurface of the mantle and the sides of the foot are white and spotted with blackish brown.
