Tomiyamichthys russus (Gobiidae) from Tanega-shima Island, Osumi Islands, Kagoshima Prefecture, Japan: first record from the Satsunan Islands and northernmost record for the species

Abstract

A single specimen (95.0 mm standard length) of Tomiyamichthys russus (Cantor, 1849), an Indo-Pacific goby associated with alpheid shrimps, was collected from Tanegashima Island, Osumi Islands, Satsunan Islands, Kagoshima Prefecture, Japan. In Japanese waters, the species has previously been recorded only from the Okinawa-jima and Iriomotejima islands (central and southern Ryukyu Islands). Thus, the Tanega-shima specimen, described in detail herein, represents the first record of T. russus from the Satsunan Islands (third Japanese record), and northernmost record for the species.
