Species of crayfish

Orconectes stygocaneyi Conservation status Least Concern (IUCN 3.1)[1] Critically Imperiled (NatureServe)[2] Scientific classification Kingdom: Animalia Phylum: Arthropoda Clade: Pancrustacea Class: Malacostraca Order: Decapoda Suborder: Pleocyemata Family: Cambaridae Genus: Orconectes Species: O. stygocaneyi Binomial name Orconectes stygocaneyi Hobbs, 2001 Synonyms[3] Faxonius stygocaneyi (Hobbs, 2001)

***Orconectes stygocaneyi***,[3][4][5][1] the **Caney Mountain cave crayfish** (also called *Faxonius stygocaneyi* in some schemes)[2] is a small, freshwater [crayfish](/source/Crayfish) [endemic](/source/Endemism) to [Missouri](/source/Missouri) in the United States. It is a cave-dwelling species known from only one cave, Mud Cave in [Ozark County, Missouri](/source/Ozark_County%2C_Missouri).[6] This cave is Protected as part of the Caney Mountain Conservation Area,[2] which covers 7,899 acres (3,197 ha) of public land administered by the [Missouri Department of Conservation](/source/Missouri_Department_of_Conservation).

## Taxonomy

The species was described as *Orconectes stygocaneyi* Hobbs, 2001.[7] It later appeared in an important catalog as *Faxonius stygocaneyi* (Hobbs, 2001)[8], but genetic data later supported affinity genus *Orconectes*, and even with data from the 16S rRNA fragment as a close ally of its type species *Orconectes inermis* Cope, 1872.[9]
