Pleuroprion chuni .—zur Strassen, 1903: 31.—Barnard, 1914: 216.— Kensley, 1975: 38 (in table).— Kensley, 1978: 33–34, fig. 15E.

Other material: Non-ovigerous female, length not recorded, South Africa, Still Bay, 35ºS, 22ºE, 200 m (station SST-11-D-5), SAM A14025. Description of paralectotype (female) (Figs 1–4): Body (Fig. 1A; completely broken, head, pereonite 1 and pleotelson missing) width of pereonites subparallel (pereonites completely broken and squeezed, thus no widthlength relationship is given). Pereonites 2–7 with large lateral extensions, pereonite 4 with 2 dorsal spines. Pereonites 5–7 subparallel and of similar length and width. Pereonite 5–7 each with 2 dorsal spines. Pleonite 1 not fused to pleotelson, without middorsal spines, lateral extension present. Remaining pleotelson with 1 dorsal spine and lateral extensions on anterior part. Antennula (Fig. 1B) peduncle article 1 wide and short, narrowing towards distal end; distally with 2 penicillate setae; article 2 0.7 times width of article 1, with 2 penicillate setae and few slender setae; flagellum article 1 short, with 1 long, slender seta distally, article 2 2.6 times longer that article 1, 2.8 times longer than wide, with 8 aesthetascs, 1 penicillate seta and 4 slender setae distally. Antenna (Fig. 1C) flagellum distally with long unguis. Labrum (Fig. 1D) with fine setae. Right mandible (Fig. 2A) molar smooth, slightly dentate on anterior edge, with some longer setae. Lacinia mobilis like structure lobate. Spine row comprising 3 dentate spines. Incisor with 2 lobes and 3 smaller teeth.
