Distribution. Lau Basin and North Fiji Basin in bathyal hot-vent fields.
Etymology. Name refers to the distribution at North Fiji Basin and Lau Basin.
Description: As the new taxon is very similar in conchological, anatomical and radular characters to Lepetodrilus schrolli Beck, 1993 ( Beck 1993) , only diagnostic characters are given here.
Shell ( Fig. 11 View FIGURE 11 ). Dimensions much higher, largest specimen: length 12.0 mm, width 8.3 mm, height 4.0 mm; apex in slightly more right-posterior position.
Radula . Rhachidian with long tapering cusp.
Soft parts. Pallial cavity deeper and shell muscles slightly shorter than in Lepetodrilus schrolli .
Dimensions. Holotype shell length 11.0 mm, width 8.3 mm, height 4.5 mm.
Remarks. No evident morphological-anatomical diagnostic character was found to separate North Fiji specimens from Lau specimens.
