The chromosomes of eight forms of the Chilopoda were comparatively investigated in this study, especially with reference to the relationship of the cytological characters upon taxonomy. The taxonomic arrangement of the studied species and their chromosome numbers here established are shown in Table 1.
The chromosomal relationship between Scolopendra subspinipes mutilans and S. s_??_ japonica was interpreted on the basis of both the morphology and the number of the chromosomes.
Though Otocryptopus rubiginosus and O. sp. are closely related belonging to the same genus, the chromosomes of these two species failed to show any morphological kinship.
The chromosomes of Bothropolys asperatus and Esastigmatobius longtitarsis belonging to the Lithobiomorpha showed a remarkable difference not only in the number of chromosomes but also in other morphological features.
Thereuonema hilgendorfi and Thereuopoda clunifera were proved to show similar chromosomal feature, being characterized by having the XY-XX sex-chromosome mechanism.
