| Distribution map | F 71912. Family - Gorgonocephalidae. |
Description The disc is flat, 11 mm diameter. The radial shields are narrow, straight-sided, contiguous proximally, divergent distally; 7–8 times long as wide, and length 0.45 times d.d. The dorsal surface is covered by skin bearing spines/granules; primary plates not visible. Disc spines or granules of one type, cylindrical. The spines are up to 0.15 mm long, and 1 times high as wide; sparsely distributed. The ventral interradial surface is with skin. The oral shields are covered in skin. The adoral shields are covered in skin. Bursal slits reduced, not bordered by spines or papillae. The jaw is as wide as long or wider than long, with one or two (tending toward a cluster), rounded apical papilla, longer than wide. Oral papillae separated by a gap from apical papillae, rounded. The oral tentacle pore is located inside the jaw, with distal oral papilla similar to other oral papillae. The specimen has five arms, branched, moniliform, 4–7 times d.d. Dorsal arm plates not visible, covered by skin, with spines/granules, extending the length of the dorsal arm; bands of hooklets. The second ventral arm plates are not visible, covered by skin. Ventral arm plates of the first free segments not visible, covered. Tentacle pores along the arm, with no scales. There are 0 arm spines on the first ventral segment, 3–4 on the first free segments. The spines are erect, restriced to the ventral surface, subequal, and 0.5–1 times as long as one arm segment, blunt, cylindrical. There are thorns, in longitudinal series on the surface from the base to the tip of the spine, on the tip or on the middle, glassy transparent shaft, with hooks. Spines also skin partially (at base) or completely covering spine.
