  • Title: Karyotype characterization of Eurysternus caribaeus: the smallest diploid number among Scarabaeidae (Coleoptera: Scarabaeoidea).
    Author: Cabral-de-Mello DC, Silva FA, de Cássia de Moura R.
    Journal: Micron; 2007; 38(3):323-5. PubMed ID: 16919467.
    Abstract:
    Eurysternus caribaeus was analyzed cytologically by conventional chromosomal staining. The species presents a diploid number of 2n=8, chromosomes with two arms and an XY sex determining mechanism. This is the first karyotype described for the genus Eurysternus and the tribe Eurysternini, and is also the smallest diploid number observed in the family Scarabaeidae and superfamily Scarabaeoidea.
