Additions to the Australian freshwater crayfish
Abstract
Since the author's paper (1951), dealing mainly with Queensland freshwater crayfish, much additional material has been examined. New species are described in the present paper and additional information is given on some other species.
Three new species of Euastacus and one of Cherax are described from the highlands of eastern New South Wales. A new genus, Euastacoides, is erected for three new species from south-east Queensland. Specimens of this new genus are in many ways similar to juvenile Euastacus but they lack the characteristic spines of that genus and though of relatively small size are mature as is evidenced by the width of the abdomen in females and the ejection of spermatophores by some males when preserved.
