Abstract

Katianira platyura, new species, is described from the midbathyal zone of the Kumano Basin, southern Japan, the first record for the family from the North Pacific. Katianira platyura differs from its congeners by having the head with a pair of broad, deeply divided, bilobed lappets; pereonite 1 laterally rounded; anterior and posterior corners of pereonites blunt; mandibular molar process rudimentary; pereopod 3 flattened and broad; distal part of pleopod 1 with 32 setae; protopod of pleopod 2 trapezoidal; tip of endopod of pleopod 2 reaching to approximately 0.9 of protopod; and broad, leaf-shaped uropods.
