Summary:
A silvery siphonfish peppered with tiny black dots, three narrow stripes along the side - one from the top of the head to the rear of the soft dorsal fin, a more distinct midlateral stripe from the snout through the eye to the tail base, and the third from the lower part of the gill cover running along the top of the light organ, a dark brown iris, whitish fins with small black speckles on the pelvic-fin spine, the first dorsal-fin spines and the posterior soft dorsal-fin rays.

Distribution

Endemic to the Great Barrier Reef, Queensland, from the Torres Strait in the north, to the Northumberland Islands Group, north of Shoalwater Bay.

Body depth 2.2–2.8 in SL, body width 1.9–2.25 in the depth; eye diameter 2.7–3.2 in HL; caudal-peduncle length 1.4–2.1 in distance between pelvic spine insertion and anal-fin origin; predorsal distance 2.0–2.2, preanal distance 1.3–1.4, prepelvic distance 8.8–11.35, all in SL. Preopercular edge with 13–25 serrations around angle and ventral edge; scales spinoid. 
Light organ above to 1st to 6th procurrent caudal rays in specimens 20–26 mm SL.
First dorsal spine 2.1–2.9 in second spine; second dorsal spine 3.7–4.9, spine of second dorsal fin 4.0–5.0, and second anal spine 4.0–5.1, all in head length; pectoral-fin length 4.1–5.5 and pelvic-fin length 3.7–4.6 in SL.

To 28 mm SL.

Similar Species

Siphamia guttulata differs from all other members of the S. tubifer group in having the predorsal scales arranged irregularly resulting in none or one proper predorsal scale.

Etymology

The specific name guttulata is from the Latin guttula (= small spot), in reference to the body 'speckled all over with minute black dots'.
