Hyas aculeata Gibbes, 1850: 171 (type locality: Key West, Florida).

Othonia aculeata – A. Milne-Edwards 1873-1880: 115 ( St Thomas); 1880: 2 (St Croix).

Pitho aculeata – A. Milne-Edwards & Bouvier 1923: 395 (St Croix). — Rathbun 1924b: 19 ( Curaçao); 1925: 357 ( St Thomas, Guadeloupe, Curaçao, Aruba). — Rodríguez 1980: 274 (Los Roques, Bonaire, Curaçao, Aruba, Curaçao). — Marcano & Bolaños 2001: 74 (Los Roques). — Lira 2004: table 1 ( Tortuga). — Tagliafico et al. 2005: table 1 (Los Frailes near Margarita).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1♀ MNHN-IU-2013-6731 (lot JL1364-1), st. GB 29, 2 m ; 1 ♀ MNHN- IU-2013-4801 (lot JL1348), 1 ♂, 1 ♀ MNHN-IU-2013-4819 (lot JL1333-2), st. GR 45, 2 m ; 1 ♀ MNHN-IU-2013-5053 (lot JL1354), st. GS 32, 2 m.

HABITAT. — Sandy bottom in lagoon terrace, loose rubble or coral matter, soft substrate and associated with aquatic vegetation. Collected 2-16 m, reported 1-4 m to 69 m (‘38 brasses’ in A. Milne- Edwards & Bouvier 1923).

DIAGNOSIS. — Five lateral teeth subequal; second and third united at base. Front narrow. Outer margin of lobe of first movable joint of antenna very arcuate.

HABITAT. — In Thalassia meadows, hard substrate, and rubble. Collected 1-16 m, reported previously 1- 11 m.

DISTRIBUTION. — Western Atlantic. West coast of Florida, Colombia, Venezuela. Lesser Antilles ICA (Guadeloupe, Trinidad), IOV (Margarita, Cubagua, Tortuga).

REMARK

First record for Guadeloupe but type-locality is Antilles in A. Milne-Edwards (1873-1880) and perhaps Guadeloupe or Martinique. Determination with doubt for specimen illustrated (MNHN-4760, fig. 8G) because lateral teeth 4-5 are reduced instead of almost as long as lateral teeth 1-3 in typical form (cf. Rathbun 1925, pl. 132, fig. 3); this specimen could be P. lherminieri instead.
