Lygistorrhina (Probolaeus) acahuizotla sp. nov., is described and illustrated based on adults from the locality of Acahuizotla in the state of Guerrero, Mexico. The species is related to Lygistorrhina (Probolaeus) alexi Huerta & Ibáñez-Bernal. The male is distinguished mainly from other congeneric species by the presence of a pair of preapical setae on the mediotergite, pale-yellow fore coxa, with brown pigmentation medially, and “U-shaped” tegmen. New records of Lygistorrhina (Probolaeus) alexi Huerta & Ibáñez-Bernal from Tecpan de Galeana, in the state of Guerrero and from Biology Station of Chamela, in the state of Jalisco, both in west Mexico, are added. A key to the species of Lygistorrhina from Mexico is provided.
