Holotype : ♀ (76 mm), 24°83.15’N, 76°37.88’W, depth: 672 m, temperature: 10.6 °C, 28 April 2014 (CMNH 38,598). Paratypes : 3♂ (73–88 mm), ♀ (69 mm), 24°83.15’N, 76°37.88’W, depth: 672 m, temperature: 10.6 °C, 28 April 2014 (♂, NHMUK 2016.67 - 69; ♀, NHMUK, 2015.3278). ♀ (74 mm, non-ovig), 24°49.53’N, 76°23.38’W, depth: 769.2 m, temperature: 8.8°C, 28 April 2014 (MTQ 34369). Diagnosis. Pleotelson with 7, broad, short spines with setation running along ~80% of the posterior margin. Uropodal lateral margins with 90–94% setation, and reduced setation on mesial margins of exopod and endopod. Description of holotype female. Body 76 mm long, length 3 times that of width. Head with ridge above eyes discontinuous; clypeal area with distal margins slightly concave, apex broadly rounded. Antenna 2 flagellum extending to within pereonite 3. Pereopod 1 ischium with 2 posteroproximal robust setae, 5 robust setae on posterodistal margin; merus with 8, short robust setae on anterodistal angle, posterior margin with 2 robust setae in proximal row, and 4 robust setae in distal row; propodus length 2 times width, with 4 robust setae on posterior margin. Pereopod 2 ischium with 2 robust setae on posterior margin, and 3 robust setae on posterodistal margin; merus with 7 short robust setae on anterodistal angle, posteromedial margin with 3 robust setae in proximal row, and 3 robust setae in distal row; propodus with 3 robust setae on posterior margin. Pereopod 7 coxa distally attenuated and curved posteriorly. Pleonite 3 extending up to pleonite 4. Uropod extending slightly beyond pleotelson; peduncle with 2 robust setae; exopod and endopod with minutely scalloped lateral and distal margins; exopod lateral margin convex proximally, sinuate distally, with 0 robust setae along margin, setal fringe continuous (90–94%); medial margin straight; distomedial corner broadly ...
