Profundulus rei Calixto-Rojas, Lira-Noriega, Rubio-Godoy, Pérez-Ponce de Léon & Pinacho-Pinacho 2023 is a new species of Middle American Killifish (Profundulidae). It’s restricted to one subbasin within the Ometepec River basin between the states of Guerrero and Oaxaca in Mexico.

The specific epithet “rei” refers to the first author’s pet cat Rei, his “companion for 11 years, during which his academic formation took place (BSc, MSc and almost all PhD), and was his constant attendant while measuring all the fish specimens for this work.” The cat’s name was inspired by the fictional character Rei Ayanami from the Japanese animation series Neon Genesis Evangelion. - Ken Lazara, FB
