( Figures 1H View FIGURE 1 , 14 View FIGURE 14 , 15 View FIGURE 15 , 18A–C View FIGURE 18 , 24C View FIGURE 24 , 25 View FIGURE 25 ; Tables 1–4a)

Type material: Holotype USNM 1112614 About USNM . Paratypes: USNM; TAMU ; ZMUM Le1–158 (DGoMB stn S36

rep. 2); Le1–159 (NGoMCS 5421 stn WC 4/3); Le1–160 (DGoMB stn RW 5/1); Le1–161 (DGoMB stn MT 4/ 3).

Type locality: Gulf of Mexico, 27°30'25"N, 89°49'23"W, 1,198 m (NGoMCS, sample 3043, station C8/1, 14.11.1984) GoogleMaps .

Material examined: Off North Carolina, 1 specimen ( Table 3a); Florida coast, 3 specimens ( Table 3b); Gulf of Mexico, 88 specimens ( Table 1); Guiana Basin, 23 specimens ( Table 4a) .

Diagnosis: Very prickly with large, sharply pointed sclerites; opaque, body to 4.5 mm, anterior trunk somewhat wider than posterior trunk, length of posterium variable from 1/3 to>3/4 trunk length, shank scarcely set off from trunk, clearly set off from knob fringed by single row of sclerites twice or more length of knob; oral shield sclerites in 2 rows. Trunk sclerites large, thick, longitudinal axis straight, base very broad, proximal end often angular, blade short, narrow, sharply ridged or striated longitudinally.

Etymology: Named in honor of the Captain Kidd Pub (Woods Hole), very famous for oceanographers and marine biologists where we have discussed a lot of our zoological and other problems… and made a lot of good friends. The feminine genitive form reflects the gender of "pub" in Spanish, German, Russian and other languages, just as "ship" is feminine (e.g., Neopilina galatheae ).

Description: External appearance ( Figs 1H View FIGURE 1 , 14A–C View FIGURE 14 ): Medium-size, to 4.5 x 1.25 mm, but width deceptive owing to large, prickly sclerites which also mask division between trunk and broad shank, posterium/ trunk index greatly variable, 0.35–0.85; holotype length 3.8 mm, anterium 0.2 mm, trunk 2.7 x 1.0 mm, shank 0.5 x 0.5 mm, knob 0.4 mm, posterium/trunk index 0.33. Oral shield 1.2 mm in height, each of 2 rows with 8– 10 sclerites, those of outer row much the largest ( Fig. 14D View FIGURE 14 ). Knob bulb- or cone-shaped, fringed by a row of very long sclerites.

Sclerites ( Figs 14G View FIGURE 14 , 15 View FIGURE 15 , 18 A–C View FIGURE 18 ): General: Large in length, base width, and blade thickness, longitudinally straight, thickened symmetrically, many proximally angular; waist distinct on all but oral shield and knob sclerites; blade narrow, sharply pointed, shorter than broad base and bent outwards from base ( Fig. 15M View FIGURE 15 ), sharply ridged and striated ( Fig. 18C View FIGURE 18 ), base almost without longitudinal striations ( Fig. 18B View FIGURE 18 ). Oral shield ( Fig. 15A View FIGURE 15 ): asymmetrical, drop-shaped with rounded proximal end, thin, to 80 x 40 x 3 µm, thickest medially, no waist. Dorsal to oral shield ( Fig. 15B View FIGURE 15 ): distally pointed, to 160 x 60 x 4 µm. Anterium ( Fig. 15C, D View FIGURE 15 ): short, broad or narrow, length of blade and base equal, to 250 x 30–95 x 7 µm, thickest medially on blade or base. Dorsal trunk ( Figs 14G View FIGURE 14 , 15F, H, I View FIGURE 15 , 18A, B View FIGURE 18 ): as in general description, blade equal to or less than 1/2 total length, to 500 x 150 x 10 µm, thickest on blade near waist. Ventral trunk ( Figs 15E,G View FIGURE 15 ): similar to those from dorsal trunk, but most shorter and slightly less wide. Shank ( Fig. 15J View FIGURE 15 ): similar to those from dorsal trunk but blade longer, to 3/4 total length, bent sharply outwards from base, to 750 x 140 x 12 µm, thickest on blade near waist. Knob ( Fig. 15K View FIGURE 15 ): relatively short needles to 200 µm. Fringing ( Fig. 15L View FIGURE 15 ): very long, straight, narrow, to 1,200 x 15 x 10 µm.

Radula and jaws: 1 examined. Jaws 680 x 320 µm ( Fig. 14E View FIGURE 14 ); radula teeth 150 µm long, serrated membrane about 110 µm, situated in middle of tooth; central plate curved, to 50 µm ( Fig. 14F View FIGURE 14 ).

Distribution: Continental slope and rise: off North Carolina ~ 850 m, Florida Coast 289–329 m, Gulf of Mexico 545–1,875 m, and Guiana Basin 508 m and 1,456 m ( Tables 1, 2, 3a, b, 4a) ( Figs. 24C View FIGURE 24 , 25 View FIGURE 25 ).

Remarks: Niteomica captainkiddae is distinguished from the other known, eastern Atlantic species N. hystrix Scheltema & Ivanov, 2000 by the much broader sclerite base with scarcely any longitudinal striations and the short blade with numerous sharp longitudinal ridges or striations.
