Abstract: The four goby species of the genus Kelloggella are among the smallest fishes known. The largest specimen recorded is 26 mm standard length. Because of the small size Qif the species, many of the features characterizing the genus and those separating the species have been overlooked or incorrectly reported. This situation has lead to the description of five species placed in five different genera. The discovery of a new species from Eniwetok and Rarotonga led to the present revision.
TL;DR: These specimens represent a new record of the genus Kelloggella from Taiwan and some external features of the specimens are presented to supplement the morphological information on Kellogggella cardinalis.
