Image of Hawaiia minuscula (Binney 1841)

Description:

Found in litter near flowpath when runoff occurs. Also found with G. pilsbryana, G. pellucida, G. contracta, two other G. sp.?, and Vallonia perspectiva. See following posts. These shells are generally more depressed than most H miniscula, so perhaps they belong in a subspecies. I'm not confident in taking them any farther than this, however. Alternatively, Helicodiscus singleyanus seems to be a very close match in some ways, and may be in this area, but I am having a really hard time determining how some of these rarer species in the different genera are actually differentiated. It seems to all be a bit of a mess, if you ask me.
