Remarks. Stigmops howensis ( Lewis, 1998b) n.comb. differs from the other species of Stigmops n.gen. by only having two large lobe-like tubercles on the cephalon, with the lateral tubercles reduced to small angular points at the base of the medial tubercles. Additionally, the dorsal pereonite tubercles show an extremely marked decrease in size from pereonite 6 to 7. The frons of this species also lacks cuticular pits that are present in the other species. Additional unusual features include an uncleft frontal lamina, a constricted pleotelson with an indented posterior margin, and long and narrow uropodal protopods. This showy species with its impressive dorsal lobes is frequently encountered in the previous surveys.
