概要

Recently rediscovered in the Hokkaido University collection, the holotype and single paratype of Lycenchelys brevimaxillaris Toyoshima, 1985 were found to differ from the original description of the species in the following characters: posision of posterior end of upper jaw and numbers of anal fin rays, gill rakers on lower gill arch, suborbital, mandibular, and preoperculer pores, and vomerine and palatine teeth. Because no significant differences were found in the counts, proportions, and other characters (e.g., interneural space insertion of first dorsal fin pterygiophore), including body color, between these type specimens and L. melanostomias Toyoshima, 1983, the recently demonstrated synonymy of the two names is confirmed. The holotype and paratype of L. brevimaxillaris have been registered in the collections of Hokkaido University, Hakodate (HUMZ), and the National Science Museum, Tokyo (NSMT), respectively.
