A systematic review of the fish genus Lycodapus (Zoarcidae) with descriptions of two new species
Six of 11 nominal species of Lycodapus, L. australis Norman, L. derjugini Andriashev, L. dermatinus Gilbert, L. fierasfer Gilbert, L. mandibularis Gilbert, and L. parviceps Gilbert, are recognized. Original descriptions and the disintegrated type do not permit adequate diagnosis of L. extensus Gilbe...
