Identification. The species is identifiable by its conical spire with straight whorl profile, a narrow, dashed, yel- low-and-black spiral band immediately above the suture, and the black columella. Even though the present specimens are both sinistral, specimens collected elsewhere in Acre present both sinistral and dextral shells ( UFAC 620, UFAC 853, from Rio Branco and Senador Guiomard municipalities, respectively). As argued by Breure and Mogollón Avila (2016), C. regalis is morphologically very close to C. regina (A. Férussac, 1823) , which is distrib- uted throughout northern South America ( Simone 2006) and might be synonymous with it. The present record, although the first specifically from Acre, is well within the species expected distribution.
