Geomerinus is a monotypic genus of centipedes in the family Geophilidae.

[1][4] This species features an elongate head and elongate forcipules, very small claws on the second maxillae, and no sternal pores; the ultimate leg-bearing segment has a narrow metasternite, scattered coxal pores, and legs with a single tarsal article.

[5] The original description of this species by Haase is based on a female specimen measuring 45 mm in length with 71 pairs of legs.

[3] The description by Brolemann is based on a larger female specimen measuring 67 mm in length, also with 71 leg pairs.

[6] The centipedes are solitary terrestrial predators that inhabit plant litter, soil and rotting wood.
