Name

Transancistrus Lujan et al., 2015

Etymology: Transancistrus is a combination of the Latin word trans (meaning across, over, or on the other side of), which refers to the distribution of this genus across rivers draining the Pacific slope of the Andes Mountains in Ecuador, and ancistrus, a root name for many Hypostominae genera having clusters of enlarged evertible cheek odontodes.
