Type material

Holotype: USNM 213519 About USNM (not examined). Type locality: off West Florida.

Material examined

MARTINIQUE • 1 ♀; E of Le Vauclin ; 14°34.2ʹ N, 60°44.8ʹ W; depth 90 m; 14 Sep. 2016; st. AD231; MNHN-IU-2016-1199 GoogleMaps • 1 ♀ gr.; same collection data as for preceding; MNHN-IU-2016-1322 GoogleMaps .

Remarks

This is the first record of this species since its original description from central West Florida by Child (1992b). The two specimens were sampled at the same station, off Le Vauclin (Atlantic coast). They are morphologically very similar to Child’s description. Unfortunately, CO1 PCR amplifications were negative for the two DNA extracts.

Distribution

Only recorded from West Florida (Gulf of Mexico) and Martinique.

Depth range

73– 90 m.
