The following description applies to all three known species of Grammatostomias.

Body moderately elongate, its depth fewer than 10 time in SL. Head with tapering snout of moderate length; lower jaw not longer than upper jaw, not curved strongly upward; bargel slender, unpigmented, usually or always broken after being caught; reported to be 7 or more times longer than SL in one specimen; end of barbel presumed to be unmodified. Pectoral fin with 4–11 rays, the anterior rays with masses of luminous material near bases; pelvic fins low on body, their insertions close together near mid-ventral lin' bases of dorsal and anal fisn about eayal in lenth, their origin approximately opposed; no doral adipose fin. Photophores in ventral row between pectoral and pelvic-fin insertions (PV) 15–18; a pale loop or line present on flanks; postorbital photphore an elongate triangle, much smaller than, to slightly longer than eye diameter; no large patches of luminous material on head behind eye, but small spots or lines often present.

To more than 20 cm.

Elongated loop with irregular zigzags in the luminous tissue (Ref. 37473).
