Sacoproteus thomasleei is a rare
species known, on Maui, from only four animals found at exposed rocky sites at
depths of about 3 m (10 ft).
Maui and Midway: may also be known from Guam.
It was first
recorded in Hawaii from Midway Atoll by Terry Gosliner and PF in
1993. Due to differences between the Guam and Hawaiian specimens there's
some question regarding whether they should be lumped as one species.
