[1] The four species in this genus are each found in one of three limited and unusually disjunct areas.

[4] While the ranges of these species all fall within a narrow band of latitude (about 35–45 °N), they are maximally separated in terms of longitude.

No other group of centipedes, and no terrestrial animals in the Northern Hemisphere, are known to exhibit such a peculiar geographic distribution.

[1] A phylogenetic analysis of the family Mecistocephalidae using morphological features places this genus in the subfamily Dicellophilinae along with the genera Anarrup and Proterotaiwanella.

This analysis also places Dicellophilus in a clade with Anarrup as a closely related sister group.
