Dyspanopeus is a genus of crabs in the family Xanthoidea, comprising two species:Dyspanopeus sayi (Smith, 1869)Dyspanopeus texanus (Stimpson, 1859)Both species were formerly included in the genus Panopeus, but were separated off into a segregate genus in 1986, based on the form of their pleopods, which differ markedly from those in Panopeus and other genera.
