<jats:title>Abstract</jats:title><jats:p>Spermatid/sperm basic chromosomal proteins from 17 species and subspecies of the genus <jats:italic>Xenopus</jats:italic> (Anura, Pipidae) were compared. Electrophoresis on acetic acid/urea/Triton X‐100 polyacrylamide gels revealed that each <jats:italic>Xenopus</jats:italic> species with a diploid chromosome number of 36, 72, or 108 showed multiple, diverse spermatid/sperm‐specific basic chromatin proteins with mobilities greater than the somatic histones. The numbers and mobilities of these proteins were characteristic of each <jats:italic>Xenopus</jats:italic> species and each subspecies of <jats:italic>Xenopus laevis</jats:italic>. Cytochemical tests revealed that the sperm basic nuclear proteins of these <jats:italic>Xenopus</jats:italic> species and subspecies were rich in arginine and lysine and contained more arginine than the nuclear proteins of somatic cells.</jats:p><jats:p><jats:italic>X. tropicalis</jats:italic> (2n = 20) and <jats:italic>X. sp. n</jats:italic>. (Zaire) displayed spermatid/sperm‐specific basic chromatin proteins which migrated within the histone H1 region of acetic acid/urea/Triton X‐100 polyacrylamide gels. Cytochemically the sperm nuclei of these species resembled those of somatic cells.</jats:p><jats:p>These observations suggest that spermatid/sperm basic nuclear proteins can be used as molecular markers for individual species and subspecies of the genus <jats:italic>Xenopus</jats:italic>.</jats:p>
