Lophopanopeus bellus is a small crab with a
carapace width of up to . The carapace is more rounded than some related species and the upper side is covered with low, rounded projections known as
tubercles. There are more prominent tubercles on the fifth, sixth and seventh segments of the
chelipeds; the legs are covered with
setae (bristles) and have black claws. The color of this crab is quite variable; its color range includes off-white, various combinations of bluish-black and red, dull dark red and nearly black, the underside is usually whitish. This crab could be confused with
Glebocarcinus oregonensis which is a similar size, but that species has spiny ridges on the
chelae instead of tubercles. ==Distribution==
