Cambarus polypilosus, a new species of stream-dwelling crayfish (Decapoda: Cambaridae) from the Western Highland Rim of Tennessee, USA

Cambarus polypilosus sp. nov. is a stream-dwelling crayfish endemic to tributaries in the Buffalo and lower Duck River drainage, and a reach of the lower Tennessee River in the Western Highland Rim of West-Central Tennessee, U.S.A. The new species is closely allied to the three members of the former subgenus Glareocola, but can be differentiated from each by a combination of characters, including body size, coloration, spination, setation, and form I male gonopod morphology. Several meristic measurements and ratios also differentiate C. polypilosus sp. nov. from Cambarus friaufi, to which it is morphologically most similar. Cambarus polypilosus sp. nov. appears to be common in cherty gravel and cobble habitats, where it is typically found in interstices at depths of 0.3 m or more below the substrate surface.

Camellia

Camellia is an industrial suburb about five kilometres east of Parramatta city centre, on the south bank of the Parramatta River. The suburb is located between Clay Cliff Creek to the west, Duck River to the east, and Grand Avenue. The major roads dissecting the suburb are Grand Avenue (east-west) and James Ruse Drive (north-south). The rail link between Rydalmere and Clyde and the spur line from it to Camellia railway station were important transport links, as were the roads that opened the suburb for industrial use. This little suburb has had no school, post office or retail outlets (other than 'a lunch shop' on Grand Avenue near Devon Street) to sustain the nearby industrial workers during the week.

Auburn

Auburn, the centre of the municipality of the same name, is in western Sydney on the main western railway line and accessible by Parramatta Road or the M4. It lies on the traditional lands of the Dharug peoples. The original vegetation of the area was open forest, dominated by woolybutt red gums, with grey box, ironbark and stringy bark. The land is slightly undulating, with a minor ridge running south along Park Road and a gradual slope west towards Duck River.
