Etymology

The generic name Macrhybopsis refers to macro from the Greek makrós (μaκρóς), long or large, and Hybopsis. The specific name relates to the San Marcos River, part of the Guadalupe system, which is the type locality.^[5] The common name is an allusion to the diagnostic nuptial tubercles on the heads of breeding males.^[6]
