Takagi (unpublished: 94) identified a goby collected in Amamioshima and Kikaijima, in Kagoshima Pref., Japan as Callogobius liolepis Koumans, and gave it a Japanese name“namerahaze”.Our study revealed that these specimens agree well with the holotype of Callogobius okinawae (Snyder), but neither with the syntypes of C.liolepis nor with the original figure of C.hasseltii (Bleeker).C.okinawae closely resembles C.hasseltii, and Tomiyama (1936: 84) and Koumans (1953: 98) regarded them conspecific.However, we found some characters are different between them (Table 1 and Figs.2 and 3).
