Justification: The holotype, and only known specimen of this species, from the Indian Museum Calcutta may be lost. It was presumably small (<30 cm total length) and was captured in the Arabian Sea at a depth of between 1,134 to 1,262 m. All aspects of the biology (including maximum size) and levels of threats are unknown and thus it is assessed as Data Deficient at this point in time. |

Habitat and Ecology [top]

| Systems: | Marine |
Threats [top]
| Major Threat(s): | Unknown. Found in waters deeper than 1,000 m and would not be of any commercial interest, so probably not greatly threatened unless it does actually turn out to have a very restricted geographic and depth range. |
