New species of the morid genus Gadella (Teleostei: Gadiformes) from the Galapagos Islands

A new species of deepwater morid fish, Gadella thysthion, is described on the basis of five specimens from the Galapagos Islands. It differs from other species of Gadella by its low dorsal and anal fin ray counts (8+56-58 and 64-66 respectively), moderate number of gill rakers (4-5+9-11), small luminous organ that is closer to the anus than the interventral line, and its dark body, bright red-orange median fins with dark bases, and melanophores on the tongue apex and the palatal midline.
