Key to the genus Cylapus Say, 1832

Cylapus clavicornis and C. festinabundus are not treated in this key as their placement in Cylapus is doubtful (see discussion under Cylapus for details). Cylapus famularis and C. funebris are also excluded from the key as specimens belonging to these species were unavailable for this study and the information coming from their original descriptions is insufficient in preparing of this key.
