Geophilidae
Geophilidae is a family of soil centipedes in the superfamily Geophiloidea and the order Geophilomorpha. In 2014, a phylogenetic analysis based on morphological and molecular data found this family to be polyphyletic. To avoid this polyphyly, authorities dismissed the families Aphilodontidae, Dignathodontidae, Linotaeniidae, and Macronicophilidae, which are now deemed to be junior synonyms for Geophilidae. Authorities also moved some genera from Geophilidae to form the family Zelanophildae in order to avoid the polyphyly of the family Geophilidae. The family Geophilidae now includes more than 650 species in more than 120 genera. This family has a cosmopolitan distribution, with species found almost worldwide. Description Species in this family are characterized by mandibles with a single pectinate lamella. Sternal pores are often present but with variable arrangements, and coxal organs are usually present and open into pits or through distinct pores. Female gonopods in ...

Aphilodontidae
Aphilodontinae is a monophyletic group of soil centipedes previously known as the family Aphilodontidae in the order Geophilomorpha. This clade is now considered a subfamily in the family Geophilidae and has been renamed accordingly. This subfamily now includes more than 30 described species distributed among four genera. Phylogeny and taxonomy In 2014, a phylogenetic analysis based on morphological and molecular data found the family Aphilodontidae nested within the family Geophilidae. To avoid paraphyly of the family Geophilidae with respect to Aphilodontidae, authorities dismissed Aphilodontidae as a separate family. Authorities now deem Aphilodontidae to be a junior synonym of Geophilidae. A phylogenetic analysis of the family Geophilidae based on morphology confirms the monophyly of the subfamily Aphilodontinae. The morphological evidence also places this subfamily in a clade with the geophilid genus '' Geoperingueyia'', which emerges as the closest relative of this sub ...

Geophilus Flavus
''Geophilus flavus'' is a terrestrial, soil-dwelling, species of centipede in the Geophilidae family. ''G. flavus'' occurs in a range of habitats across central Europe, North America, Australia, New Zealand and other Tropics, tropical regions. Geophilomorpha, Geophilomorph centipedes, like centipedes generally, are primary Predation, predators, hunting predominantly in underground soil burrows or above ground leaf litter. Their consumption behaviours are influenced by environment and seasonal factors. Given their lack of economic value and marginal medical significance, ''G.flavus'' remains largely understudied in mainstream research. Some recent studies have detailed the evolutionary development of ''G.flavus'' and Geophilidae generally, illustrating developed predatory features like forcipule venom glands. Description These centipedes are yellow and may grow up to in length. They are sightless, and rely on specialised sensory organs to sense movement, humidity and light. Li ...
