A new species of the wholly freshwater hymenosomatid crab genus Limnopilos Chuang & Ng, 1991, is described from Tonle Sap River in the lower Mekong drainage, Cambodia. This is the fourth species known, and the second one from Indochina. The type species, of Limnopilos, L. naiyanetri Chuang & Ng, 1991, was from the Chao Phraya drainage to the west in central Thailand. The new species is characterized by the presence of a rostrum, relatively shorter ambulatory legs and a different structure of the male first gonopod. Limnopilos sumatranus Naruse & Ng, 2007, is also recorded from southern Peninsular Malaysia for the first time.
Une nouvelle espèce du genre de crabe Hymenosomatidae, Limnopilos Chuang & Ng, 1991, entièrement d’eau douce, est décrit du fleuve Tonlé Sap dans le bassin versant du Mékong inférieur, au Cambodge. C’est la quatrième espèce connue, et la seconde d’Asie du Sud-Est. L’espèce-type du genre Limnopilos, L. naiyanetri Chuang & Ng, 1991, était connue du bassin versant du Chao Phraya à l’ouest dans le centre de la Thaïlande. La nouvelle espèce est caractérisée par la présence d’un rostre, de pattes ambulatoires relativement plus courtes et une structure différente du premier gonopode mâle. Limnopilos sumatranus Naruse & Ng, 2007, est aussi signalé pour la première fois dans le sud de la Malaisie péninsulaire.
