Arthotheliopsis serusiauxii
Arthotheliopsis serusiauxii is a species of leaf-dwelling lichen in the family Gomphillaceae. It was first formally described as a new species in 1997 by Robert Lücking, as a member of genus "Echinoplaca". The type specimen was collected in Costa Rica, growing on the leaves of a dicotyledon. The specific epithet honours Belgian lichenologist Emmanuël Sérusiaux. In 2005, Lücking, Sérusiaux, and Antonín Vězda transferred it to genus "Arthotheliopsis" after a molecular analysis of the Gomphillaceae helped to clarify the phylogenetic relationships in the family.
