title: [Attempts at inter-specific hybridization in Sphaeroma (Crustacea Isopoda Flabellifera)].
abstract: An interspecific hybridization between five tunisian species of the genus Sphaeroma has been attempted. All the trials failed whatever the crossing attempted. The lack of natural hybrids between forms living together constitutes a fundamental criterium for specific discrimination.
