Abstract
The poorly known porcellanid crab Lissoporcellana miyakei Haig, 1981 is reported for the first time from Japanese waters. The present specimen greatly extends the geographical range of this species to the northeast. The fresh coloration of L. miyakei is depicted for the first time in a photograph. In addition to morphological characters, L. miyakei differs from L. nakasonei (Miyake, 1978) in coloration.
