Remarks. Kalliapseudes bamberi n. sp. material was borrowed from Roger Bamber (NHM) and was identified as Phoxokalliapseudes (= Kalliapseudes ) gobinae ( Bamber, 1998) . However, close examination revealed that it is a new species and differs markedly from P. gobinae by the following characteristics: 1) the rostrum is less pronounced, 2) the pleotelson has a row of posterior plumose setae, 3) the first peduncle article of the antennule lacks ventral spiniform setae, 4) the inner flagellum of the antennule has only three articles, 5) the male antennule only has five aesthetascs, 6) the labrum complex lacks cusps, 7) the male chela has a different dentition, 8) the dactylus of pereopods 2 and 3 has a digitiform lobe, 9) the dactylus of the male pereopod 6 is not as long as that of P. gobinae , and 10) the basal article of the uropod is much shorter and lacks a spiniform seta on the inner distal corner. Kalliapseudes bamberi n. sp. is unique in having a row of posterior plumose setae on the pleotelson.
