MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1 sp. MNHN-IU-2013-6610 (lot JL625), st. GD 17, 30 m ; 1 sp. MNHN-IU-2013-4139 (lot JL893), st. GD 33, 130 m; 1♀ juv. MNHN-IU-2013-5917 (lot JL902), st. GR 29, 20 m.

DIAGNOSIS. — Rostrum hood-shaped, hollow beneath. Fingers of mature male narrowly gaping. Last leg about one and a half times as long as carapace. Dactyli of legs falcate, that of second leg contained two and a half or more times in the length of the propodus.

HABITAT. — On seagrass Halophila stipulacea , among hydroids, on loose rubble and rocks, on sand-mud and sand-calcareous algae bottoms. Collected 20-130 m, reported 1- 140 m.

DISTRIBUTION. — Western Atlantic. North Carolina, Florida, Bermudas, Gulf of Mexico, Honduras, Brazil ( Paraiba, Pernambuco and Rio de Janeiro). Lesser Antilles VI ( St Thomas), ICA (St Barthélemy, Guadeloupe, Martinique, Trinidad), IOV (Margarita).

REMARKS

Felder et al. (2009, note 280) indicate that a few specimens from the Gulf of Mexico are problematic, exhibiting character states intermediate between C. riisei and C. algicola .

Coryrhynchus sidneyi (Rathbun, 1924) ( Fig. 2N View FIG )

Podochela sidneyi Rathbun, 1924a: 1 View in CoL ( type locality: off Cape Hatteras, North Carolina).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1♂ MNHN-IU-2013-4064 (lot JL970-2), st. GD 35, 66 m ; 1 ♂ MNHN-IU-2013-5968 (lot JL44), st. GR 12, 21 m; 1♂ MNHN- IU-2013-5937 (lot JL1260), st. GR 40, 53 m.

DIAGNOSIS. — Dactyl of last three legs elongated more than half as long as their respective propodites. Palm of adult male very slightly inflated. Sternal segments of male forming flat, sharp-edged plates.

HABITAT. — Rocky sublittoral, reef environment. Collected 21- 66 m, reported 1- 187 m.

DISTRIBUTION. — Western Atlantic. Off Cape Hatteras, North Carolina, Gulf of Mexico. Cuba. In Lesser Antilles ICA (Guadeloupe).

REMARK

This is a first record for Guadeloupe and for Lesser Antilles.

Ericerodes gracilipes ( Stimpson, 1871) View in CoL ( Fig. 3A View FIG )

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1 ov. ♀ 8.3 × 4.8 mm MNHN-IU-2013-4199 (lot JL973-2; first identification as Podochela sp.; in loan with D. Felder, April 2014), st. GD 35, 66 m.

DIAGNOSIS. — Rostrum long, spiniform, unarmed. Carapace much constricted behind orbits. Fingers widely gaping in adult male. Legs filiform.

HABITAT. — On corals, calcareous algae, hard substrate, rubble and soft bottoms. Collected 66 m, reported 2- 120 m.

DISTRIBUTION. — Western Atlantic. Off Cape Lookout, North Carolina, Gulf of Mexico, Colombia, Surinam, Brazil. Lesser Antilles ICA (Guadeloupe, Barbados).

REMARK

This is a first record for Guadeloupe. This specimen was initially in a lot of ‘ Podochela spp.’. It has been sent to D. Felder ( April 2014) for further studies, including molecular sequencing.
