Abstract:
The true freshwater crab fauna of Borneo (Sarawak, Sabah, Brunei and Kalimantan) is rich, and 40 species from the two major freshwater crab superfamilies Gecarcinucoidea and Potamoidea are presently known (Bott, 1970; Holthuis, 1979; Ng, 1986a, b, c, d; Ng & Goh, in press; Ng & Yang, 1986). Yet, as recently as 1979, Holthuis described one new genus and five new species from Sarawak, suggesting that the freshwater crab fauna in this part of the world is still far from completely known. For the superfamily Potamoidea, only 11 species have so far been recognised from Borneo, nine of which belong to the genus isolapotamon Bott, 1968. This paucity in species is very surprising indeed, considering that Peninsular Malaysia, which has a much smaller land area, has 21 species and subspecies of potamoids (unpublished data). Through the kindness of Mr. Charles M.U. Leh, Zoologist in the Sarawak Museum, the author was able to examine the extensive materials contained there as well as make some collections in the field. Not surprisingly, study of this material revealed that many of the species had been incorrectly identified. Twelve species of isolapotamon are presently recognised from Borneo. Six are from Sarawak, two of which are here described as new; isolapotamon consobrinum (De Man, 1899) isolapotamon doriae (Nobili, 1900) isolapotamon collinsi Holthuis, 1979 isolapotamon grusophallus Ng & Yang, 1986
