Prostomium: Trilobed; one pair of eyespots.

Mouth tentacles: Papillose.

Branchiae: Four pairs of branchiae in two groups separated by a distance equal to one branchial base diameter; three branchiae in each group in transverse row, fourth branchia located behind middle one of the three; branchial bases on each side fused.

Paleae: Long and stout with curved tips; 10–23 chaetae on each side.

Special features: None

Distribution

Svalbard and Bear Island; 35–170 m (Holthe 1986a).

Similar species

The long stout paleae, in combination with the long abdomen (17 uncinigers), makes it unlikely to confuse adult complete specimens of Ampharete goesi with any other Ampharetidae in Norwegian waters.
