Description

Stephonyx scutatus (Griffiths, 1977)

Euonyx scutatus Griffiths, 1977: 98, fig. 3.— Barnard & Ingram, 1990: 3 (key).— Barnard & Karaman, 1991: 485.

Stephonyx scutatus.— Lowry & Stoddart, 1989: 521.— Diffenthal & Horton, 2007: 40 (key).— Senna & Serejo, 2007: 13 (key).— Narahara et al., 2012: 1505 (key).

Types. Holotype female, 16 mm, SAM A13652.

Type locality. Cape Basin, South Atlantic Ocean (34°37'S 17°03'E).

Habitat. Marine.

Depth range. 2900 m (Griffiths 1977).

Remarks. Stephonyx scutatus is different from other species of Stephonyx in the dorsal body carination and in the peculiar conical hump of coxa 5. The mandibular molar, described as ‘a large plate with raised margins’ is not like the setose tongues or triturating molars usually found in scavenging uristids and particularly in Stephonyx.

Distribution. South Atlantic Ocean. Cape Basin (Griffiths 1977).
