Carpophiline-ID: An interactive matrix-based key to the carpophiline sap beetles (Coleoptera, Nitidulidae) of Eastern North America

We present Carpophiline-ID, a matrix-based LucidTM key, for the adult
stage of the known species of Carpophilinae (Coleoptera: Nitidulidae) of
North America, east of the Mississippi River. We provide an overview of
the features and technical specifications used to build the key. The list
of terminal taxa used in the key represents the most current regional
account for Carpophilinae, a beetle subfamily of agricultural and
ecological importance. We discuss the value of matrix-based, free access
keys for the identification of difficult taxa.
