Pseudaeginella campbellensis Guerra-García, 2003: 185–189 , figs. 9–13. — Lacerda et al., 2011:11–14, fig. 5C.— Iwasa-Arai et al., 2019: 5–9, fig. 7.— Shin et al., 2023: 170–171.

Material examined. NIWA 125329 , 2 specimens, Ringdove Bay , Antipodes Islands, New Zealand, 49°42.38298’S 178°47.15814’E, 5–25 m, on SCUBA, from Macrocystis sp. on boulders and rock wall, coll. D. Freeman, 10/03/2009 .

Diagnosis. Pereonite 1 with dorsal acute projection, bent forward. Pereonite 2 without dorsal projection anteriorly, with two parallel dorsal small projections medially, low straight dorsal projection distally, without minute anterolateral acute projections (one on each side) or lateral acute projections (one on each side) near the coxa of gnathopod 2. Pereonite 3–5 without dorsal projections. Pereonites 3–4 with acute lateral projections near the gills. Pereopods 3–4 with two setae distally. Pereonite 5 with small anterolateral projections (one on each side). Gnathopod 1 dactylus bifid. Basis of gnathopod 2 with distal projection near coxa, basis longer than pereonite 2 length. Gnathopod 2 propodal palm slightly setose, with one mid-medial tooth and preceding excavation, posterior corner defined by tooth and distal spine. Anterior margin with one large anteromedial projection. Gills as long as wide. Right mandibular incisor with six teeth, palp article 3 with apical robust seta.
