Type material

Holotype: USNM 81099 (not examined). Type locality: Logger-head Key , Tortugas, southwest Florida.

Material examined

MARTINIQUE • 1 ♂; Presqu’Île de la Caravelle; 14°46.5ʹ N, 60°51,5’W; depth 15 m; 22 Sep. 2016; st. AB350; MNHN-IU-2016-1302 .

Remarks

Only one specimen was collected, from which we did not succeed in amplifying the CO1 barcode sequence due to the poor quality of the DNA extract (probably due to the advanced state of decay of the specimen, which hardly consists of more than an empty cuticle, indicating that it was probably dead upon sampling). This species is generally rare in samplings, though Child (1979) examined a rather rich collection at the Smithsonian Tropical Reseach Institute in Panama. The species was recorded in Martinique by Müller (1990a) in Baie de Tartane, so both records of this species in Martinique are from the region of Presqu’Île de la Caravelle.

Distribution

Typically Caribbean, with one record on the Pacific shore of Mexico (Oaxaca).

Depth range

0– 5 m. We extend this depth range to 15 m.
