Eophrynidae is a family of the extinct arachnid order Trigonotarbida.^[1] Eophrynids lived during the Carboniferous period in what is now modern Europe and North America. The family is probably found within the "eophrynid assemblage" clade: (Aphantomartus (Alkenia (Pseudokreischeria (Kreischeria (Eophrynus + Pleophrynus))))).^[2]
