Holotype, Tasmanian Museum and Art Gallery, Hobart G1756 (male); allotype, Tasmanian Museum and Art Gallery, Hobart G1757 (female); paratypes, Tasmanian Museum and Art Gallery, Hobart G1758 (2 male, 2 female), G1759 (2 male), G1760 (2 male, 1 juv.).Distribution
The distribution of E. cisternarius is given by Suter (1977); since then the known range has been extended eastward to Castra Falls in the northern region of Tasmania and to the Gordon Dam in the southwestern region. The species has not been found on any Bass Strait islands and is therefore considered to be endemic to the Tasmanian mainland. The southern-most localities for this species are also those for the genus. Richardson and Swain (1980) reported that E. cisternarius was not found in the Olga Valley, south of the Gordon River and that Parastacoides tasmanicus tasmanicus "...replaces it in the southern most part of (their) study area...". There appears to be no a priori reason why E. cisternarius should not be found further south of the Gordon River (although it is most unlikely to be found south and east of the Serpentine Impoundment due to the already extensive searches conducted by members of the Zoology Department at the University of Tasmania in that region).References
