What is "carpinatia"

The gens Carpinatia was an opulent Roman family that grew to prominence towards the end of the Republic. The most prominent member of the family, Lucius Carpinatius, gained his reputation as one of the publicani in Sicily during the last government of Verres, a government with whom he was very intimate and which would ultimately lead to his family's demise. Cicero describes Lucius as pro-magister, or deputy manager of the publicani, and calls him a second Timarchides, referring to one of the chief agents of Verres in his robberies and oppressions. Lucius Carpinatius was eventually convicted and punish with castration, the Carpinatia family faced dishonor and fell into poverty from which it never recovered.
