Cyphocaris johnsoni Shoemaker, 1934 View in CoL
( Figure 11 View Figure 11 )
Cyphocaris johnsoni Shoemaker, 1934:1 View in CoL ,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 View Materials ) GoogleMaps . 1 female, same collection data ( MOUFPE 20189 View Materials ) .
Type locality
Porto Rico Deep GoogleMaps , 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 View 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 View Figure 11 ), with long narrow eye; pereonite 1 smooth, without a strong dorsal spine; gnathopod 1 ( Figure 11c View Figure 11 ) palm acute, serrate, bearing long robust setae; gnathopod 2 ( Figure 11d View Figure 11 ) palm acute, weakly excavate; pereopod 5 ( Figure 11e View Figure 11 ) basis posterior margin with a long and dorsally serrate spur; pereopods 6–7 ( Figure 11f–f View Figure 11 ) basis posterior margin serrate, posterodistal corner produced into an acute lobe; telson ( Figure 11i View Figure 11 ) narrow, distinctly longer than uropod 3 ( Figure 11h View Figure 11 ), apex acute. In addition, we provide an illustration of the maxilla 1 ( Figure 11b View Figure 11 ), 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).
