Within the genus Orconectes, 5 of the 6 troglobites vari- Orconectes is a genus of freshwater crayfish, native to the eastern United States. F. immunis can be distinguished from F. virilis by the presence of a notch near the base of the dactylus (finger) of the claw, which is not found in F. The first recorded escape was a single individual in a small canal in the Rhine valley of Baden-Württemberg in 1997. A 50% majority rule Bayesian consensus tree of focal and comparative Faxonius species resulting from analysis of all genes (COI, 16S, 28S, and GAPDH). Orconectes immunis (Hagen, 1870) Faxonius immunis is a species of crayfish in the family Cambaridae. Orconectes (Faxonius) limosus Rafinesque 1817 Keith A. Crandall, James W.

Dates. It can survive in areas with large fluctuations in the amount of available water, by burrowing into the ground when the surface waters recede.[4]. Adapted from USGS Rusty Crayfish Fact Sheet (2007). While the colouration of the claws is distinctive, it can be difficult to use that to identify a specimen without reference specimens for comparison. [5] It is believed to have been introduced to a number of states in New England, including Massachusetts, Maine, New Hampshire, Rhode Island and Vermont. Orconectes (Faxonius) wrighti Hobbs 1948 Hardin crayfish Form I male from Hardin, Co. Tennessee.

[6] It has since been recorded from other locations in Europe, including the German state of Rhineland-Palatinate, as well as in France. Rusty crayfish were not found in Wisconsin in a 1932 survey, but populations have rapidly expanded throughout Wisconsin lakes and streams since their introduction around 1960 (Capelli and Magnuson 1983). were significantly similar to that obtained in our study, even despite reclassification of spiny-cheek crayfish from the Orconectes genus to the Faxonius genus . This diversity often occurs among closely related species, suggesting that sexual selection and/or the need for a mechanism promoting sexual isolation has played at least some role in the generation of biological diversity.
