N2 - Two new species of homalorhagid kinorhynchs from the deep-sea Guinea Basin are described. Pycnophyes nubilis sp. nov. is easily recognized by the presence of paradorsal setae on segment 1; middorsal processes on segments 1–10, progressively increasing in length towards the posterior segments; and middorsal process on segment 10 extending over the last trunk segment. Pycnophyes farinellii sp. nov. is distinguished by middorsal elevations on segments 2–9 and laterodorsal and ventromedial setae on segments 2 and 9 only. Moreover, males of the latter species lack ventromedial tubes on segment 2—a very uncommon feature among the genus. The systematic significance of this character is discussed in detail.
