Acheilognathus hondae

Acheilognathus hondae also known as Seoho bitterling is a species of freshwater ray-finned fish in the genus Acheilognathus. It is endemic to South Korea.

Named in honor of K. Honda, director, Agricultural Station at Suigen (Korea), "who obtained for us a fine collection from the pond at this station". Following this single specimen, two further specimens were collected in the same place in 1935 by T. Mori. As no further specimens have been collected since, it is now considered extinct.
