Found at Reserva Ecológica de Guapiaçu (REGUA), in Cachoeiras de Macacu municipality in state of Rio de Janeiro in southeastern Brazil on 30.XI.2019. Female Diogmites?
Looking at this again, the marginal scutellar bristles appear to be present, which separates Diogmites from Blepharepium. So I agree that this is Diogmites, and probably conspecific with your other photos.
