Cyphocaris johnsoni Shoemaker, 1934:1,fig. 1. – Gurjanova, 1962: 67, fig. 8. – Ortiz, 1979: 19. – Hughes and Lowry, 2015: 21.

Material examined

1 female, 17.8 mm, dissected and illustrated, Potiguar Basin, MT 83, initial trawl coordinates 4.4405°S, 36.4308°W, final trawl coordinates 4.4905°S, 36.4026°W, Rio Grande do Norte state, Brazil, initial depth 1950 m, final depth 1880 m, 4 May 2011, R / V Seward Johnson col. (MOUFPE 20188) . 1 female, same collection data (MOUFPE 20189) .

Type locality

Porto Rico Deep, North Atlantic Ocean (4.4405°S, 36.4308°W and 4.4905°S, 36.4026°W).

Distribution and bathymetry

Puerto Rican Deep, North Atlantic Ocean, 567–732 m deep (Shoemaker 1934; Hughes and Lowry 2015). Slope of Rio Grande do Norte state (between 4.4405°S, 36.4308°W and 4.4905°S, 36.4026°W), Brazil, between 1880–1950 m deep (current study) (Figure 23).

Remarks

The species was described by Shoemaker (1934), based on material collected during the Johnson-Smithsonian Deep-Sea Expedition in the Puerto Rican Deep, North Atlantic, and was not recorded since then (Hughes and Lowry 2015). Therefore, this is the first record of the species from the South Atlantic, Brazil, expanding the species’ bathymetric range from 567–732 to 1880–1950 m deep.

The female collected in our study matches the original description based on the following characters: deep head (Figure 11a), with long narrow eye; pereonite 1 smooth, without a strong dorsal spine; gnathopod 1 (Figure 11c) palm acute, serrate, bearing long robust setae; gnathopod 2 (Figure 11d) palm acute, weakly excavate; pereopod 5 (Figure 11e) basis posterior margin with a long and dorsally serrate spur; pereopods 6–7 (Figure 11f–f) basis posterior margin serrate, posterodistal corner produced into an acute lobe; telson (Figure 11i) narrow, distinctly longer than uropod 3 (Figure 11h), apex acute. In addition, we provide an illustration of the maxilla 1 (Figure 11b), which was not described clearly in the original description, showing characters such as: inner plate setose, with an apical robust seta; outer plate setal teeth produced as a distal corona in a modified arrangement (STA and STB 3-cuspidate, STC 5-cuspidate, STD 4-cuspidate, ST1 2-cuspidate, ST2 1-cuspidate, ST3 2-cuspidate, ST4 3-cuspidate, ST5 5-cuspidate, ST6 6-cuspidate, and ST7 9-cuspidate).
