Glossodoris tomsmithi is a terribly attractive small to moderate sized chromodorid which is readily identified by the multiple small dense opaque nodal spots on the dorsal surface overlying a darker background, and the presence of a white emarginated notum. The only other Glossodoris species found here which is similar, is
G. pallida, which unlike G. tomsmithi, has several larger central opaque markings overlying a white translucent body, as well as a yellow emarginated notum.
I've collected a total of eight specimens, although others have been seen, but not collected. All collected specimens were found at the same site (Horseshoe Cliffs), and at the same depth (3m).
