A new carapid fish, Tetragondacnus spilotus gen. et. sp. nov., is described from a single specimen collected off Sumatra, Indonesia. This unusual species chiefly differs from all confamilials in having the following combination of characters: dorsal fin origin in advance of anal fin origin, first neural spine a wing-like process larger than second neural spine, no rocker bone, no predorsal bone, no supraneurals, no upper jaw teeth, no developed gill rakers, parapophysis of third centrum enlarged, 13 precaudal vertebrae, 11 caudal fin rays, unmodified dorsal and anal pterygiophores, presence of scales, swim bladder simple and large, squarish mouth with two lower lip lobes, oral valve with thick median septum, united branchiostegal membranes, and large dark blotches on the body. Subfamilial status for the new species is proposed.
