Colour patterns in Ceylonese freshwater crabs (Potamonidae)
1970
Fernando, C.H.
In the present paper some preliminary remarks are made on the colour patterns of all the Potamonidae of Sri Lanka. In the opinion of the author more detailed studies will show that the colour pattern of each species is a useful diagnostic aid even with difficult species like those belonging to the "Ceylonensis" complex (Fernando, 1960). Fernando (1960, 1961) has described the species of Potamonidae. Eight species are known all belonging to the genus Paratelphusa. Only one species has been illustrated in colour so far (Fernando, 1960). Black and white pictures of all the other species except Paratelphusa soror (Zenthner) have been given in Fernando (1961). Paratelphusa soror is illustrated in the present paper.
