Euprognatha inermis A. Milne-Edwards, 1878: 183, pl. 35, fig. 2, Guadeloupe [à une assez grande profondeur]. - A. Milne-Edwards, 1880a: 7, St John, Norman (Flanagan Passage), St Vincent (Grenadines) [R/V Blake, 27-127 brasses]. - A. Milne-Edwards & Bouvier, 1923: 374, Guadeloupe, St Vincent (Grenadines) [R/V Blake, st. 238, Grenadines, 127 brasses; '… j'ai sous les yeux le type décrit et figuré par A. Milne-Edwards et je crois bien qu'en fait cette espèce ne diffère de la précédente (E. rastellifera) que par son front plus ou moins saillant et plus étroit. Si cette partie du corps présente des variations chez les Euprognathes, il y aura vraisemblablement lieu d'identifier cette espèce avec la précédente'] - Accepted as Euprognatha rastellifera Stimpson, 1871 in WoRMS (2016).
Euprognatha rastellifera - A. Milne-Edwards, 1880a: 7, St Croix, Martinique, St Vincent, Grenada, Barbados [R/V Blake, 73-248 brasses]. - A. Milne-Edwards & Bouvier, 1923: 373, St Croix, Guadeloupe, Martinique, St Vincent, Barbados, Grenada [R/V Hassler, Barbades, 100 brasses; R/V Blake, st. 132, 134, 115-248 brasses, Santa Cruz, st. 206, 210, Martinique, 170-191 brasses, st. 232, St Vincent, 88 brasses, st. 253, Grenade, 92 brasses, st. 272, 273, 290, Barbades, 73-103 m]. - Santana & Tavares, 2008: 318, St Kitts. - Carmona-Suárez & Poupin, 2016: 365, Guadeloupe, Karubenthos 2012, 2 males MNHN-IU-2013-5484 (lot JL217), st.

Felder May 2018: Inachoididae juvenile, genus?]; 1 female ov. MNHN-IU-2013-5421 (lot JL1064), st. GD37, 60 m.
Euprognatha rastellifera spinosa - Santana & Tavares, 2008: 318, St Kitts [Treated as a synonym of E. rastellifera] - Euprognatha rastellifera spinosa Rathbun, 1894 is accepted as E. rastellifera in WoRMS (2016).
Remark: Several lots (MNHN-IU-2013, 4120, 4131, 4137, 5584, 5587), attributed to E. rastellifera in Carmona-Suárez & Poupin (2016, Fig. 3L) corrected into Batrachonotus fragosus Stimpson, 1871 by D.L. Felder (com. pers. May 2018).

Euprognatha rastellifera – Coelho & Ramos, 1972: 207, Brazil Amapá. — Mantelatto et al., 2020, Brazil Amapá.
Euprognatha acuta – Barreto et al., 1993: tab. 1, Brazil Amapá. — Melo, 1996: 204, Brazil Amapá. — Melo, 1998: 460, Brazil Amapá. — Coelho et al., 2008: 20, Brazil Amapá. See remark.
Distribution/Habitat – WA; Marine; 81–708 m
Remark – The distinction between Euprognatha rastellifera Stimpson, 1871 and E. acuta A. Milne-Edwards, 1880 have been for a long time very difficult due to the great variation in the ornamentation of the carapace (Williams 1984; Felder et al. 2009, note 291; Carmona-Suárez & Poupin, 2016). Santana & Tavares (2008: 326) have finally recognized only one valid species, E. rastellifera, with a highly variable morphology. It is distributed widely in the WA from off Georges Bank to Uruguay (Mantelatto et al., 2020).

Comment(s) on data
If Euprognatha acuta is the 'southern form' of E. rastellifera in western Atlantic, then Guadeloupe records could belong to E. acuta instead of E. rastellifera.
WoRMS list E. acuta as valid whereas Felder et al. (2009) only indicate E. rastellifera, without distinction between the two forms indicated in Rathbun (1925) (E. rastellifera marthae and E. rastellifera acuta) with this comment 'Both Williams (1984b) and Soto (1986) discuss difficulties in separating apparently sympatric subspecies of this taxon'
MNHN-IU-2013-5484, st. GD02 (80 m), JL217, 2M (+1 F ov. 5.8x4.1 mm with spines of carapace much longer, photo labo = Aepinus septemspinosus)
