A single, deep-sea gadiform fish, Melanonus zugmayeri Norman, 1930 (Melanonidae) specimen (194.9 mm standard length) was captured off southwestern Taiwan. This species had been hypothesized to have a circumtropical or subtropical distribution, but only a handful of records exist. Since it had never before been reported in Taiwan, the morphology and coloration pattern of this first collected Taiwanese specimen were described herein.
