Upper Arkansas River system in southwestern Missouri and northwestern Arkansas.

Habitat

Streams and shallow burrows along them.

Remarks

Hayes (1973:111) reported what he interpreted to be intergrade populations between O. (P.) nana and O. (P.) macrus in Delaware and Ottawa counties, Oklahoma, but in his recent revision of the genus, Fitzpatrick (1987a:58) maintained specific status for they crayfishes.

Conservation Status

Currently stable.

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.
