Chromosome Numbers of Some Diplocardian Earthworms (Megascolecidae- Oligochaeta)

Information on gonadal chromosome numbers of 11 species of the genus Diplocardia (Megascolecidae) indicates the probability of polyploidy. A haploid number of 22 might be assumed for this genus. A species with the highest known number (ca. 198) shows the greatest morphological divergence from what,...

Zusammenfassung:Information on gonadal chromosome numbers of 11 species of the genus Diplocardia (Megascolecidae) indicates the probability of polyploidy. A haploid number of 22 might be assumed for this genus. A species with the highest known number (ca. 198) shows the greatest morphological divergence from what, otherwise, is a reasonably stable generic type.
