A supplementary report on an additional species of the genus Coreoperca confirmed in the Oyodo River system, Miyazaki Prefecture in 2017

In December 2017, a single individual of the genus Coreoperca was collected from the Oyodo River system in Miyazaki Prefecture, southern Japan. Based on photographic evidence, it was determined that the individual is different from both Coreoperca kawamebari and Coreoperca herzi which have already been recorded from the river system as introduced species. Although the individual was not preserved as a specimen, it was identified as C. whiteheadi due to its deep body and wide interorbital area based on the photographs. It represents the first introduced record of the species in Japan. Consequently, the number of introduced species of the genus Coreoperca confirmed from the Oyodo River system in Miyazaki Prefecture is at least three. A new standard Japanese name “Nan-etsu-oyanirami” is proposed for the species, based on a specimen collected from Guangxi, China.
