Material examined. Champasak Province. Morning market at Pakse city, 1 femele (CL 66.5 mm), 1 ovig. female (CL 58.5 mm), 12 July 2009, coll. S. Ito et al.
Remarks. Macrobrachium rosenbergiiis one of the best-known freshwater prawns in the world. The identity of two distinct geographical populations (eastern and western forms) have long been a subject of taxonomic and nomenclatural controversy, although the results of morphological and DNA analyses have suggested that they could be different species (Wowor & Ng 2007, 2008). The present specimens well fit the morphological characteristics of the western form, currently as M. rosenbergii(see ICZN 2010; Ng & Wowor 2011), by having a marked rostral crest and smooth inter spine surfaces on the second pereopods as well as the absence of the posterior submedian plate on the fourth thoracic sternite (Wowor & Ng 2007).
Distribution. Macrobrachium rosenbergiiis originally distributed in southern Asia ( Jayachandran 2001) and the western part of south-eastern Asia, demarcated by the Huxley’s line (de Bruyn et al.2004; Wowor & Ng 2007; Ng & Wowor 2011), although it has occasionally been reported outside of its natural habitat as a consequence of human introduction. The presence of M. rosenbergiiin southern Laosis believed to be derived from aquaculture ponds of this species in north-eastern Thailand. Recently, colonisation of this species was found in Madagascar( Hanamura et al.2008).
