Procambarus natchitochae


}}
''Procambarus natchitochae'', or the Red River creek crayfish, is a crayfish native to the Red River basin and Bayou Teche in Texas, Louisiana, and Arkansas. Its distribution is given by the IUCN (here ), whereas a slightly different Louisiana map is provided in the "Crawfishes of Louisiana", which excludes Bayou Teche 〔 〔 ''P. natchitochae'' has a distribution of approximately 46,000 km2.〔
==Identification==

An individual crayfish can be identified to a group of a few species within the genus and subgenus ''Procambarus (Pennides)'' by looking at a few distinguishing characteristics. Two pairs of cervical spines, a broadly open areola, and lateral rostral spines are diagnostic physical features that characterize ''P. natchitochae'', ''P. vioscai'', ''P. dupratzi'', and ''P. pentastylus'' from other species of crayfish.〔 Color is not always a reliable characteristic in identification, but ''P. natchitochae'' (and the three other species above) generally have a dark brown saddle on the posterior part of the carapace and dark lateral stripes on the abdomen.〔 Form I male gonopod characteristics or collection location are required for species level identification.〔
