A phylogenetic assessment of in (, ): introduction of new genera, and the resurrection of .

During entomopathogenic fungal surveys conducted in Thailand, 15 specimens tentatively classified under were identified. To gain a comprehensive understanding of their taxonomy, molecular phylogenies using combined LSU, , , and sequence data, together with morphological examination of several spp. from previous studies were conducted. The analyses revealed distinct clades representing independent lineages within the . These clades were further characterized by different asexual morph types and the respective hosts they parasitize. In this context, we resurrected the genus to accommodate 12 known species previously classified under , found on diverse hosts. We propose four new genera - , , , and from species previously identified as . Notably, certain species associated with spiders and parasitic on were reclassified into the new genera and , respectively. Moreover, we introduce four novel species in found across a diverse range of moth families: , , , and . Additionally, we provide descriptions and illustrations of the sexual morph linked to and , along with a second type of synnemata seen in and . To assist with their identification, keys to the genera , , and are provided, but should not be used to replace molecular identification.
