Summary

Karyotypes of 16 taxa of the New World harvester ant genusPogonomyrmex are presented. Species representing both North American subgenera are examined, including members of all four complexes of the nominate subgenus. The nominate subgenus is characterized by a diploid number of 32, whereasEphebomyrmex species have 2n=36 (P. (E.) huachucanus) and 2n=58−62 (P. (E.) imberbiculus). Chromosome polymorphism was identified only in the latter species.

Resume

Les caryotypes de 16 taxa de la fourmi moissonneuse du genrePogonomyrmex ont été étudiés. Des espèces représentatives des deux sous-genres de l'Amérique du Nord ont été examinées, incluant des membres des quatre complexes du sous-genrePogonomyrmex. Le sous-genrePogonomyrmex est caractérisé par un nombre diploide de 32, alors que les espèces du sous-genreEphebomyrmex possèdent 2n=36 (P. (E.) huachucanus) et 2n=58−62 (P. (E.) imberbiculus). Un polymorphisme chromosomique n'a été identifié qu'avecP. (E.) imberbiculus.
