Fauna of New Guinea - Freshwater Crustaceans

Freshwater Crustaceans

There are freshwater crabs and freshwater shrimps in New Guinea, but generally these are poorly known and often they have not yet been evaluated taxonomically. As of 2007, 17 species of Caridina, 22 species of Macrobrachium and 6 species of Holthuisana (formerly included in Austrothelphusa) are known from New Guinea.

There are more than 20 species of Parastacid crayfish of the genus Cherax in New Guinea. With eight endemics, by far the greatest diversity is found in the Paniai Lakes.
