This deep-living, cryptic species is only known from two specimens recorded at two widely spaced localities. It likely has a wider distribution than is currently known. The holotype was collected via rotenone from a deep vertical wall. Previous to capture, it was observed near a coral head within a small group of other members of the same species. Little is known on its ecology, life history, population and the full extent of its distribution. Therefore, it is listed as Data Deficient.

Geographic Range [top]

Range Description:This species has been recorded in the western Atlantic where it is only known from two specimens collected from two localities: the holotype was captured using technical diving methods and rotenone at 87 m depth from a deep coral wall off Lee Stocking Island in the Bahamas and a second photographed specimen was later confirmed from Grand Cayman Island (R. Robertson pers. comm. 2014). It is a deep-living cryptic species which may have a larger distribution than is currently known (Sparks and Gruber 2012). It has an estimated extent of occurrence (EOO) of 190,391 km2 (based on a minimum convex polygon drawn around the extent of its range on a 50+ m bathymetric layer).

Population:The holotype was observed within a group of four or five other specimens previous to capture (Sparks and Gruber 2012).
Current Population Trend:Unknown
Additional data:

Habitat and Ecology [top]

Habitat and Ecology:The single site from which this species was captured is described as a fringing barrier reef with a steep vertical wall comprised of ledges and undercuts. It was taken via rotenone from an overhanging ledge in very near proximity to a small coral head at 87 m depth. The single specimen from which it is known has a length of 1.1 cm SL (Sparks and Gruber 2012).
