Abstract

Parazacco is a genus of freshwater fish in the family Cyprinidae, being native to China and Vietnam. There are currently two species recognized in this genus, i.e., P. fasciatus and P. spilurus. In the present study, we described samples of this genus collected in Phia Oac-Phia Den National Park, Cao Bang Province, Nam Xuan Lac Species and Habitat Conservation Area, Bac Kan Province and Tien Yen River, Quang Ninh Province. The results show that they have differences in morphological characteristics, such as shape of lateral line, a broad and dark longitudinal tripe on body and pharyngeal tooth between them with species of Parazacco recorded in Vietnam and even among samples in this study. Therefore, these samples have not been identified to species level. These findings provide fundamental information for further studies on the taxonomy of this genus in Northern Vietnam.
