Troglocambarus is a monotypic genus of troglobitic crayfish, endemic to Florida.

[4] Troglocambarus maclanei is found underground in Hernando, Marion, Alachua, Columbia, Gilchrist and Suwanee counties,[2] and is named after Mr. William A. McLane who first collected it.

[3] It is commonly called the North Florida Spider Cave crayfish.

[5] It is only found in subterranean waters and was first recorded in Squirrel Chimney, 11 miles north-west of Gainesville, Florida.

It is distinguished from other genera by the great enlargement of the third maxillipeds.
