<p><i>Cambarus </i>(<i>Cambarus</i>)<i> appalachiensis</i> is a stream-dwelling crayfish endemic to the greater New River basins of Virginia and West Virginia. The new species is morphologically most similar to <i>Cambarus sciotensis. </i>Cambarus appalachiensis can be differentiated from <i>C. sciotensis</i> by its more elongated chelae which possess a single mesial row of tubercles, reduced to no tuberculation on the dorsal-longitudinal ridge of the dactyl, and reduced lateral impression. <i>Cambarus sciotensis</i> has a more subrectangular chelae with two rows of mesial margin tubercles on the chelae, as well as both a pronounced dorsal-longitudinal ridge and pronounced lateral impression. Several chelae meristic ratios also differentiate <i>C. appalachiensis</i> from <i>C. sciotensis</i>. Within the New, Gauley, and lower portions of the Greenbrier basins <i>C. appalachiensis</i> is the dominant tertiary burrowing <i>Cambarus </i>species, and as such, is considered stable across its range.</p>
