Euastacus hystricosusKeith A. Crandall
TypesThe holotype and allotype of E. hystricosus have been lost from the Queensland Museum (fide Riek, 1969:896) and could not be found for this study. Riek (1956: 1-2; 1969:896) named lectotypes (including a "holotype", "allotype", and "paratypes") from Elaman Creek, Maleny (AM P13044). This move was invalid as lectotypes can be designated only from a series of syntypes. A single neotype may be nominated if the type series is lost but "only in exceptional circumstances where a neotype is necessary in the interests of stability of nomenclature" (International Code of Zoological Nomenclature, Art. 75a). It is here regarded that a neotype need not be designated for E. hystricosus.
Distribution and HabitatThe species inhabits streams in wet sclerophyll and rainforests at elevations above 550 m a.s.l. in the Conondale Range and Maleny areas west of Nambour, south-east Queensland. The species occurs in the Mary River system and was recently also collected from a tributary of the Brisbane River.
