Herein we document the occurrence of Holbrookia approximans in the state of Aguascalientes, Mexico, after a hiatus of 43 years since the last record, at Las Negritas, in the Municipality of El Llano, representing a new municipality record. Additionally a new locality for Zacatecas at Mesa los Encinitos, Municipality of Pinos, represents the highest altitude record for the species.
