GENUS BENTHOBIA DALL, 1889 (1)

Type species: Benthobia tryonii Dall, 1889 ; OD.

Synonym: Nux Barnard, 1960 . Type species: Nux alabaster Barnard, 1960 ; OD.

Remarks: In the absence of anatomical data, Simone (2003) considered Nux a separate genus, pointing out its close affinity to Benthobia . The radula of N. alabaster is nearly identical to that of Benthobia ( Barnard, 1960) and there are no good reasons to consider it a separate genus. The mantle lobe (called anal siphon by Simone 2003) is moderately pronounced and simple.
