Abstract

Janirid isopod, Janiralata sagamiensis Shimomura, 2006 is newly reported from Korean waters. This species can be distinguishable from its congeners by the following characteristics: the cephalon has a distinct anterolateral projection on the anterolateral margin; the frontal margin of the cephalon is lacking rostrum; the coxal plates are visible in dorsal view; the pleotelson is rounded distally without a posterolateral point; the first pleopod of the male has a pair of protrusions distally; the third pleopodal exopod is lacking plumose setae. In this paper, the detailed description and illustrations of the species are provided with a key to known Janiralata species in the surrounding waters of Korea, including China and Japan.
