A new species of the pontoniine shrimp genus Palaemonella Dana, P. hachijo,
is described and illustrated on the basis of single male specimen from a s
ubmarine cave at Hachijo-jima Island, Izu Islands, southern Japan. It close
ly resembles P. dolichodactylus Bruce, but is readily distinguished by the
antennal spine overreaching the distal margin of the antennal basicerite, t
he posteroventral margin of the fifth abdominal somite armed with an acute
tooth, and the ambulatory propodi not segmented.
