In a catalogue prepared on the Hemiptera of the Massimiliano Spinola Collection in the Torino Museum, Italy, 16 species were placed under the generic name Corixa, and two under the generic name Sigara. In ten of the taxa, the author was claimed to have been Spinola himself. However, only two valid taxa have been generally accepted, and the rest are either synonymic or only collection names. The present paper reveals the true identity of all the species of the Corixidae in the Spinola Collection.
