Etymology.

The new genus-group name is a combination of Zapotec, the principal indigenous people in the region of the type locality, and -toma (derived from the Greek, tome or tomeus, meaning, “separation”, “cutting”, or “cutter”), a suffix generally used in the generic names of pelecotomines. The gender of the name is feminine.
