We report on the first scientific results with the recently commissioned PUCHEROS spectrograph, mounted at the 50 cm telescope of the Pontificia Universidad Catolica near Santiago, Chile. A hitherto unknown candidate Be+sdO binary was identified, o Pup. If confirmed, it would be the fourth member of this class. Such stars have obtained their rapid rotation through binary mass transfer and now consist of a Be star and a hot subdwarf.

Presented in "Circumstellar Dynamics at High Resolution", Foz do Iguaçu, Brazil, February 27 - March 02, 2012, ASP Conf. Series, in press.
We would like to note that the concentrated series of observations discussed by Koubský et al. (2012, A&A 545, A121) began one week after that conference ended, so it was not possible for us to reference them in our work.
