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.[3] 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 [3][4] P. natchitochae has a distribution of approximately 46,000 km2.[4]
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.[3] 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.[3] Form I male gonopod characteristics or collection location are required for species level identification.[3]
Conservation status
Procambarus natchitochae live in streams and ditches with flowing current, clear to cloudy water, and rocky to sandy substrates.[3][4] The species is endemic to the United States and is listed as a species of least concern by the IUCN.[4]
NatureServe gives P. natchitochae a global rating of G5, or 'secure', and a national ranking of N5 for 'secure',[5] while at the state level, Louisiana ranks it as S4, for 'Apparently secure', and Arkansas and Texas rate it as SNR, or 'State Not Ranked'.[5] The American Fisheries Society ranks it as 'Currently Stable'.[4] Conservation assessment is lacking for this species because there are little available data on the population or threats, other than the current species distribution.[5]
