, as it pertains to urosomite 1. However several morphological differences are found between our specimens and Hirayama’s: 1) maxilla 1 palp biarticulate (nonarticulated in original description); 2) maxilla 2 inner lobe with 3 apical setae (2 setae in original description); 3) uropod 3 peduncle slightly longer than outer ramus, slightly shorter than inner one (peduncle shorter than rami in original description); 4) uropod 3 inner ramus slightly longer than outer (both rami equal in length in original description). These slight differences (except the biarticulate palp) are deemed insufficient to warrant the erection of a new species for our material at this time, especially as we have not examined Hirayama’s
