Abstract

Representatives of a rare species, Diaphanosoma senegal Gauthier, 1951, are recorded for the first time from seven localities in Northeast Thailand and in one locality in the south of Vietnam. The known species range is thereby much expanded to the east, from West Africa to South-East Asia. Close comparative examination of specimens from the latter region has revealed morphological differences from all other representatives of the species, inhabiting the vast area from West Africa to India and Bangladesh, thus substantiating their attribution to a new subspecies, D. senegal isanensis. The description of the new taxon is supplemented by notes on biology and zoogeography of the species.
