﻿AbstractAmphipods in the parvorderOedicerotidiraare burrowers, furrowers, or surface skimmers. Members of the parvorder share a well-developed posteroventral lobe on coxa 4, an equilobate coxa 5, an immensely elongate pereopod 7 that differs in structure from pereopod 6, and an entire telson. Within the parvorder, only the familyOedicerotidaehas been documented from Bocas del Toro, Panama, represented by two species. This research documents a range extension forHartmanodesnyei(Shoemaker, 1933) and describes a new species ofSynchelidiumSars, 1892. An identification key to the species of CaribbeanOedicerotidaeof Panama is provided.
