However, as of December 2024 BirdLife International's Handbook of the Birds of the World retains the species as Xolmis dominicanus. Because the move of this species and several others from Xolmis resulted in species of several genera being called "monjita", the SACC is seeking a proposal to adopt new English names. The black-and-white monjita is the only species in the genus Heteroxolmis and has no subspecies. == Description == The black-and-white monjita is 20 to 20.5 cm (7.9 to 8.1 in) long.
