New species peyritschiella styngeti identified on staphylinidae in Mexico, highlighting biodiversity within laboulbeniales.
One new species of Laboulbeniaceae, Peyritschiella styngeti, is described and illustrated. Characterized by appendages with a black constriction at the base, perithecia with four papillae on the apical zone, cruciform bilateral symmetry, and an extremely melanized receptacle. This species was observed on the stylus of the staphylinid Styngetus deyrollei, highly specific to this rove beetle species, which are distributed in the tropical montane cloud forest in Mexico. Currently, the Laboulbeniales mycobiota in Mexico comprises 82 species, with 11 described growing on species of the Staphylinidae family. Additionally, a compilation of the Laboulbeniales species reported for Mexico and for Staphylinidae species is presented.
