Abstract
Morgan, G.J., 1986. Freshwater crayfish of the genus Euastacus (Decapoda-Parastacidae)
from Victoria. Mem. Mus. Via. 47: 1-57.
Six Victorian species of Euastacus, E. diversus, E. neodiversus, E. kershawi, E. yarraensis,
E. bispinosus and E. armatus are redescribed. Two new species, E. woiwuru from higli
country east of Melbourne and E. bidawalus from far eastern Victoria are described. External
morphological characters, measurement ratios and gastric mill ossicles are employed in the
revision. A key to the Victorian species is presented. The condition of the male cuticle parti-
tion and spination of the chela, thorax and abdomen are the most useful characters for distin-
guishing species.
