Lophocochlias parvissimus is a species of sea snail, a marine gastropod mollusk in the family Tornidae.

The very small, white shell is umbilicate, turbinate, not nacreous, with a conic brownish spire.

The body whorl has six strong, smooth spiral keels, narrower than the intervals, which are flat and crossed by numerous retractively axial threads, which are much narrower than their intervals.

The outer lip is strengthened by a rounded external rib or varix a short distance behind the edge.

[2] This marine species occurs in the Pacific Ocean off Hawaii and Tuvalu.
