抄録

<i>Argis lar</i> and <i>A. hozawai</i> are commercially important deep-sea crangonid shrimps of closely similar morphology. A previous study described three morphological characters to distinguish <i>A. lar</i> and <i>A. hozawai</i> was based on comparison of specimens of different size, raising the possibility that these characters are features of intraspecific differences related to body size. In the present study, mitochondrial DNA fragments encoding the cytochrome oxidase subunit I (COI) gene were sequenced in order to reassess the morphological criteria purported to separate <i>A. lar</i> and <i>A. hozawai</i>, based on specimens collected under a synchronous and sympatric sampling design. Two distinct clades were detected (<i>p</i>-distance 7.72%) supported by high bootstrap values, which completely correspond to <i>A. lar</i> and <i>A. hozawai</i> identified by morphological characters. Accordingly, <i>A. lar</i> and <i>A. hozawai</i> should be treated as two distinct species for appropriate fisheries management.
