Five species, including one new species, are recognised from the region: <i>P. echinata</i> Dana, 1852 (type species of the genus), <i>P. abei</i> Kubo, 1937, <i>P. furcata</i> Kubo, 1937, <i>P. okutanii</i> Ohé and Takeda, 1986, and <i>P. ostlingos</i> sp. nov. The geographical range of <i>P. okutanii</i> is extended to the northern South China Sea off southwestern Taiwan, representing the first discovery of species of the genus from tropical waters in the western Pacific. These species are diagnosed and illustrated. They are classified into two informal species groups, the P. echinata species group (including <i>P. echinata, P. abei </i> and <i>P. okutanii</i>, and two species from other regions, <i>P. areolata</i> Faxon, 1893 and <i>P. australis</i> Hanamura, Wadley and Taylor, 1999) and the <i>P. furcata</i> species group (<i>P. furcata</i> and <i>P. ostlingos</i> sp. nov.). New findings on the morphology of the genus are presented. The monophyly of <i>Paracrangon</i> is highly corroborated by a number of autapomorphic characters, but its relationship to other crangonid genera remains obscure. A revised key to aid in the identification of the species of <i>Paracrangon</i> is presented. ER -
