Orconectes inermis Cope, 1872 |
Orconectes is a genus of cave dwelling freshwater crayfish, endemic to suitable habitats in the eastern United States. Surface dwelling species, formerly categorised here, were moved to Faxonius in 2017. [1]
Due to their subterranean habitat, they are usually depigmented, often blind, and are long-lived. Ages of 176 years have been claimed for O. australis, though this was reduced to ≤22 years in a 2012 study. [2]
The genus Orconectes was erected in 1872 by Edward Drinker Cope to house Astacus pellucidus (now Orconectes pellucidus ) and his new species, Orconectes inermis . [3]
Prior to the 2017 review by Oxford university, the genus contained 85 species in 11 subgenera. The Faxonius subgenus was raised to a full genus, and the majority of species formerly recorded as Orconectes were moved there. Following the review, approximately 8 species are known: [1]
