Troglocambarus is believed to be the sister group to Procambarus.[5] It is only found in subterranean waters and was first recorded in Squirrel Chimney, 11 miles north-west of Gainesville, Florida.[6] T. maclanei has no body pigment and spends most of its life upside-down, hanging from the ceiling of a cave. It is distinguished from other genera by the great enlargement of the third maxillipeds.[2] It is unknown what T. maclanei feeds on.[4]

Troglocambarus maclanei is listed as "imperiled" by NatureServe,[4] and as Near Threatened on the IUCN Red List.[1]
