Cortés-Suárez 2018; Cortés-Suárez et al. 2021).In Mexico, ocular malformations have been scarcely documented (see Venerozo-Tlazalo et al. 2022).Forrer's Leopard Frog (Lithobates forreri) is distributed from central Sonora and southwestern Chihuahua to the south along the Pacific coastal plain in Mexico; nevertheless, its presence is uncertain in other countries of Central America (e.g., Guatemala, Honduras, Nicaragua, and Costa Rica) (McCranie 2015; Luque-Montes et al. 2018; IUCN SSC Amphibian Specialist Group 2020; Frost 2021).Herein, we report the first published case of microphthalmia in Forrer's Leopard Frog (L.forreri) from Mexico.At 2200 h on April 30, 2022, during a night survey, we encountered a juvenile female Forrer's Leopard Frog (L.forreri) with an ocular malformation known as microphthalmia according to Meteyer (2000).The affected eye was small in size and not fully fused to the eyelid (Fig. 1).The individual (63 mm SVL) was found on the edge of a pond surrounded by tropical dry forest modified for recreational activities in the village of El Walamito, Municipality of Culiacán, Sinaloa, Mexico (24.373242 °N, 107.036803 °W; elev.136 m asl).Once the individual was examined and photographed, it was released in the same place where it was found.
