Arthrophaga myriapodina is a fungus in the Entomophthorales that parasitizes the millipedes Apheloria virginiensis corrugata, Boraria infesta, and Nannaria sp.

[1] Arthrophaga myriapodina was first collected by Roland Thaxter from North Carolina in 1886 on Boraria infesta, but he did not formally describe or name it.

In 1916, A. T. Speare sent Thaxter additional specimens labelled as Entomophthora myriapodina, but the name was never validly published.

Kathie T. Hodge, Ann E. Hajek, and Andrii Gryanskyi showed that A. myriapodina is distinct from related taxa including Entomophthora and formally named it as the type of a new genus.

[1] Arthrophaga myriapodina forms distinct white to light brown pustules that emerge between the segments of a millipede.
