A new pycnogonid species of the genus Pycnogonum is described from Flemish Cap (Northwest Atlantic Ocean) at 1453-1462 m depth. Pycnogonum bamberi sp. nov. is compared with its congeners, from which it can be distinguished by the combination of a glans-shaped proboscis, the low, transverse ridges that lie on the dorsodistal surfaces of the first coxae and femora of all legs and the distinctive conical tubercle on the mid-dorsal surface of the fourth segment of the trunk.
