Pseudonesimus cedrosianus Kilgallen & Lowry 2014, comb. nov.

Description

Pseudonesimus cedrosianus (J.L. Barnard, 1967) comb. nov.

Schisturella robusta cedrosiana J.L. Barnard, 1967: 72 (key), 77, fig 35.― Barnard & Ingram, 1990: 31 (key).― Larsen, 2007: 14 (key).

Types. Holotype, male, 6.8 mm, LACM CR 1960 - 078.9 (originally AHF 6028).

Type locality. Cedros Trench, off Baja California (27°54'25"N 115°40'00"W), 1720–1748 m depth.

Habitat. Unknown.

Depth range. 1720–1748 m (J.L. Barnard 1967).

Remarks. This species differs from P. robustus (J.L. Barnard, 1961) by the more acute lateral cephalic lobes, the more broadly rounded epimeron 3, and uropod 3 peduncle which is twice as long as wide in this species, but only 1.5 × longer than wide in P. robustus.

Distribution. Eastern Pacific Ocean. Cedros Trench (J.L. Barnard 1967).
