Plesionika acanthonotus - Paulmier, 1993: 17, Martinique [Trap 300 m]. - Poupin, 1994: 22, Guadeloupe [R/V Polka, 500-600 m, det. A. Crosnier, with hesitation because some characters are those of the sibling species, Plesionika geniculatus (A. Milne-Edwards, 1883) (MNHN)].
Plesionika geniculatus/acanthonothus - Guadeloupe, Karubenthos II 2015, field det. J. Poupin, st. CP4618, 25 June 2015, 16°22.74'N, 60°45.86'W, 780-828 m, MNHN-IU-2013-19094; st. CP4643, 28 June 2015, 15°44.98'N, 61°11.07'W, 609-611 m, MNHN-IU-2013-19163.
Comment: rostrum of Karubenthos specimens match well Pandalus geniculatus A. Milne-Edwards, 1883 (pl. 25). Currently Plesionika geniculatus (A. Milne-Edwards, 1883) is considered as a synonym of Plesionika acanthonotus (Smith, 1882) but Crosnier (in Poupin, 1994: 23) has indicated that specimens from Guadeloupe differ from P. acanthonotus in several aspect and are more closely related to P. geniculatus. Additionnal specimens collected during Karubenthos should perhaps be useful to re-instate P. geniculatus reported from Guadeloupe (600 m) and also Portugual (1350 m) (Udekem d'Acoz, 1999: 129).
