Procambarus (Lonnbergius) acherontis Lonnberg 1894

Orlando Cave Crayfish

Keith A. Crandall, James W. Fetzner, Jr., and Horton H. Hobbs, Jr.
Containing group: Procambarus


Holotype, Zoological Institute, Academy of Sciences, Leningrad, Russia 1/4412 (1 specimen).

Type Locality

Subterranean rivulet about 42 feet (12.6 m) from surface, near Lake Brantley, Seminole County, Florida (probably Sec. 3, T. 21S, R. 29E); these co-ordinates were furnished by R. Franz who searched the tax records of the property of Mr. A.E. Sjoblom on which the well mentioned by Lonnberg was situated.


Known from only one locality in Orange County, Florida, and three in Seminole County, Florida (see Franz and Lee, 1982).


Springs and underground streams.


Hobbs (1940a:393), endeavoring to clarify the confusion engendered by Faxon as to the indentity of the species (see P. (O.) lucifugus lucifugus) and believing that both of Lonnberg's types were lost, designated neotypes from the Palm Springs locality. As informed by Dr. Y. Starobogatov, one of Lonnberg's specimens is still extant (see above); thus, the neotype designation should be rejected.

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.
