REMARK

Euprognatha acuta A. Milne-Edwards, 1880 is listed as a valid species in WoRMS but the differences with E. rastellifera s.s. are not clear ( Williams 1984; Felder et al. 2009, note 291). Without comparative material no effort is made herein to separate these two species/subspecies. The specimens have been sent to D. Felder (April 2014) for further analysis, including

molecular biology (MNHN-IU-2013-4120, 4131, 4137, 5421, 5587, 5662).

Pyromaia acanthina

Lemaitre, N. H. Campos & Bermúdez, 2001 ( Fig. 3M )

Pyromaia acanthina Lemaitre, N. H. Campos & Bermúdez, 2001: 765 (type locality: 11°23’25.2”N, 74°12’3.6”W, Caribbean coast of Colombia).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1♀ ov. 12.9 (without rostrum) × 8.8 mm, MNHN-IU-2013-5931 (lot JL173), st. GN04, 150 m.

DIAGNOSIS. — Carapace with prominent spines. Meri, carpi, and propodi of ambulatory legs with numerous small spines. A key of Pyromaia species is in Lemaitre et al. (2001).

HABITAT. — Not indicated during KARUBENTHOS 2012 nor in the original description. Collected 150 m, reported 196- 321 m.

DISTRIBUTION ( Lemaitre et al. 2001). — Carribean coast of Colombia. Now also Lesser Antilles ICA ( Guadeloupe).

REMARKS

This is a first record for Guadeloupe and Lesser Antilles. This specimen was recorded as Gen. sp. after Besse 2013 workshop. It was re-examined by the second author in MNHN, December 2015. It is somewhat intermediate between Pyromaia propinqua Chace, 1940 and P. acanthina Lemaitre, N. H. Campos & Bermúdez, 2001 . The dorsal margin of the rostrum has a few spines and the spines on lateral margin of carapace are reduced (as in P. propinqua ) but median spines of carapace (meso and metagastric, cardiac and intestinal) are long and there are minute spines on the ambulatory legs (reduced on carpi), as in P. acanthina . Male first pleopod is very distinctive for these two Pyromaia species (cf. Lemaitre et al. 2001, fig. 5a-c) but cannot be checked on female specimen examined. Pyromaia ‘? acanthina ’ has been also tentatively recognized from photos during KARUBENTHOS 2015, between 111-660 m (Poupin & Corbari in press).
