Cambarus fetzneri

The mountain population of Cambarus monongalensis, occurring in the Allegheny Mountains and Ridge and Valley physiographic provinces of the Virginias, has been described as Cambarus fetzneri by Loughman et al. (2019).

This species is common to locally abundant throughout its limited range in West Virginia. It is only known from a few populations in Virginia where it is considered rare. Although the West Virginia populations are protected by land use practices, threats exist for populations outside of these protected lands.

This species is limited to the Allegheny Mountains and western Ridge and Valley physiographic provinces in Virginia and West Virginia at elevations above 1,800 feet (550 m). It is known from one Virginia and six West Virginia, Counties.

Although this species was thought to possibly occur in Garett County Maryland, collecting efforts have failed to find it (Loughman et al. 2019).

This species was collected from a total of 28 sites, however, collection locales were not included in the original description of the species (Loughman et al. 2019). They state that "this species is common to locally abundant throughout its distribution in West Virginia, though limited to a few known sites in Virginia."

This species is highly sought by collectors, and it is known that over collection for the pet trade has resulted in the destruction of once thriving colonies (Loughman et al. 2019). Other localized threats include development of natural gas plays, timbering, and urban development (Loughman et al. 2019). Threat scope is likely to be restricted to a small percentage of the population.
