We know of no features that separate H. dispar from H. hawaiiensis. The type locality for H. dispar is the Mediterranean Sea (off Messsina, Sicily), North Atlantic, while the type locality for H. hawaiiensis is the Hawaiian Archipelago in the central North Pacific. The two species have not been compared side by side, and, therefore, have not been synonymized. Hopefully, DNA data will tell us before long if careful morphological comparisons are needed. H. dispar has priority but our access to specimens in excellent condition and illustrations of H. hawaiiensis is responsible for our presenting a description of the latter species. Therefore, if you wish to see a virtual description of H. dispar, please go to the H. hawaiiensis page.

This page is a Tree of Life Leaf Page.

Each ToL leaf page provides a synopsis of the characteristics of a group of organisms representing a leaf at the tip of the Tree of Life. The major distinction between a leaf and a branch of the Tree of Life is that a leaf cannot generally be further subdivided into subgroups representing distinct genetic lineages.

For a more detailed explanation of the different ToL page types, have a look at the Structure of the Tree of Life page.
