Abstract:

A new eelpout, Lycenchelys monstrosa, is described from the lower continental slope of the Gulf of Panama, eastern Pacific Ocean. It is distinguished from all other Lycenchelys in the region by possessing nine preoperculomandibular pores, eight or nine suborbital pores, one postorbital pore, no occipital or interorbital pores, 126–132 vertebrae and far posterior dorsal fin origin, with three to seven free dorsal pterygiophores. The species appears to be somewhat peculiar among eelpouts in that 11 of the 12 known specimens lack pelvic fins; one of the fish without pelvic fins is the only one known with palatine teeth. Both characters have been used at the generic level in eelpouts. The species appears closest to three other congeners with nine preoperculomandibular pores, known from the North Pacific and Antarctic lower slopes. Characters of the new species lend support to earlier conclusions that the deeper living Lycenchelys have undergone morphological modification in a similar manner, though they do not necessarily form a monophyletic group.
