Short, J. W. and Meek, P., 2000. New records of Macrobrachium (Crustacea: Decapoda: Palaemonidae) from Christmas Island, Indian Ocean.

The first collection of Macrobrachium (river prawns, river shrimps, freshwater prawns or long-armed prawns) from caves on Christmas Island, Indian Ocean is reported. Represented in the collection is the wide-ranging M. lar (Fabricius, 1798), and M. microps Holthuis, 1978, previously known from freshwater caves in the Southwest Pacific. The former is more typically an epigeal species and has previously been reported from surface waters on Christmas Island, while the latter appears to be an obligate hypogeal species.
