Trichoderma tlahuicanensis sp. nov. (Hypocreaceae), a novel mycoparasite of Fusarium oxysporum and Phytophthora capsici isolated from a traditional Mexican milpa

We formally describe this new taxon as Trichoderma tlahuicanensis sp. nov., in honor of the indigenous pre-Hispanic Tlahuica people of Morelos, Mexico. Our work demonstrates how a phylophenetic framework, combining genomic, phylogenetic, genetic diversity, and evolutionary analyses, provides a powerful approach to species delimitation. This integrative strategy confirms the recognition of T. tlahuicanensis as a distinct species while offering a methodological pathway for peers engaged in fungal systematics.
