The bee subfamily Panurginae is reported for the first time from the middle Miocene crater lake of Öhningen, southwestern Germany (Baden-Württemberg: Konstanz). A single specimen, likely a male, is preserved as a rather faint compression in limestone and was labelled more than 75 years ago as possibly Osmia Panzer . The fossil is certainly one of the less-well preserved bees from the Öhningen locality and is the kind of specimen that might quickly be relegated to incertae sedis and passed over for better material. However, close inspection with sufficient lighting reveals subtle characters divulging the fossil’s identity. In fact, the bee is of the tribe Panurgini and is here described as a new subgenus and species therein. Panurgus ( Chronopanurgus ) tribacus subgen. & sp. n. is distinguished from other panurgines, thereby representing not only the first panurgine fossil from Öhningen but from all Eurasia.
