Recent attempts to produce a phylogenetic hypothesis for Endomychidae based on morphology alone have failed to resolve the relationships between many of the subfamilies and between Endomychidae and other Cerylonid-Series taxa. A new phylogenetic analysis was conducted using molecular sequence data from ribosomal (18S, 28S), nuclear protein-coding (wingless), and mitochondrial (COI) genes. The resulting hypothesis was used to resolve the subfamilial relationships within the group and identify the placement of the family within the Cerylonid-Series.
