Arthotheliopsis hymenocarpoides is a species of foliicolous lichen in the family Gomphillaceae. It is the type species of the genus Arthotheliopsis. Both the genus and species were described as new by Finnish lichenologist Edvard August Vainio in 1896. The type specimens were collected by botanist from Saint Vincent, where they were found growing on the leaves of a tree in Bonhomme forest. This collection was part of his work for the West India Natural History Exploration Committee. At the time, Vainio was a renown expert on tropical lichens, so the specimens were sent to him for identification.
