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.
