Four new species of Pleurosigma are described from the region of Alexandria in Egypt: P. williamsii sp. nov. , P. mariutensis sp. nov. , P. ramlehensis sp. nov. and P. rushdyensis sp. nov. The taxa had been previously misidentified as P. rigidum W. Sm., P. elongatum W. Sm., P. speciosum var. sumatricum H. Perag. and P. formosum W. Sm., respectively. Due to the close resemblance of P. williamsii, P. mariutensis , P. ramlehensis and P. rushdyensis to P. rigidum , P. elongatum , P. speciosum var. sumatricum and P. formosum and the lack of good illustrations of these previously described species, their valvar features are shown and discussed in relation to the new taxa. © 2002 The Linnean Society of London, Botanical Journal of the Linnean Society , 2002, 140 , 77–92.
