Abstract

The freshwater goby, Odontobutis hikimius n. sp., is described based on specimens collected from Shimane Prefecture, Japan. The species is unique among Odontobutis in having a connection between the transverse and longitudinal sensory papillae rows on the opercle. It is also distinguishable from congeners by the following combination of characteristics: only a short sensory canal present posterodorsally to eye, lateral scale rows 38–49. Diagnosis of the genus Odontobutis is revised and a key to the seven known species is provided.
