Chromosomal polymorphism in Cassida syrtica Boh. (Coleoptera: Chrysomelidae).
Intraspecific polymorphism with regard to autosomes has been observed in Cassida syrtica, where an additional large autosome (marker chromosome) has been encountered in the diploid as well as the haploid set of chromosomes. The diploid number for the normal type is 18 (n = 8 + Xyp). Its polymorphic form reveals a diploid set of ninetten chromosomes with an exceptional karyotype (n = 8 + 1 Mt + Xyp).
