The Cordycipitaceae family of insecticidal fungi is widely distributed in nature, the most complex order Hypocreales (Ascomycota), with members displaying a diversity morphological characteristics and insect host ranges. Based on Bayesian evolutionary analysis five genomic loci(the small subunit ribosomal RNA (SSU) gene, large (LSU) translation elongation factor 1-α (tef1-α) largest polymerase II (rpb1), second (rpb2), we inferred divergence times for Cordycipitaceae, improving internal phylogeny this fungal family. Molecular clock analyses indicate that ancestor Akanthomyces sensu lato occurred Paleogene period (34.57 Mya, 95% HPD: 31.41–37.67 Mya), species appeared Neogene period. historical biogeography was reconstructed using reconstructing ancestral state phylogenies (RASP) analysis, indicating it likely originated Asia. Combined characterization phylogenetic were used to identify taxonomically place within Cordycipitaceae. These include following: (i) two new species, namely baishanensis sp. nov. Samsoniella sanmingense nov., (ii) record isolated from infected Lepidopteran host, Blackwellomyces lateris, (iii) genus Niveomyces, sporothrix-like asexual morphs, N. multisynnematus, dipteran insects (flies), (iv) known (hyper-) mycoparasite, Liangia sinensis, fungus Ophiocordyceps globiceps (Ophiocordycipitaceae) growing host. Our data provide significant addition diversity, ecology, aspects

Introduction Entomopathogenic fungi play a crucial role in the ecological regulation of insect populations and can be exploited as resource for pest control, sustainable agriculture, natural products discovery. These their infected hosts are sometimes highly coveted part traditional medicine practices. Here, we sought to examine biodiversity entomogenous subtropical forests China. Methods Fungal-infected specimens were collected from various sites Fujian Province, China, purified isolates obtained through laboratory cultivation isolation techniques. Molecular characterization specific target genomic loci was performed on fungal isolates, used phylogenetic analyses using Bayesian inference maximum likelihood methods elucidate taxonomic relationships. Microscopy describe morphological features isolates. Results Through comprehensive two-year survey Province via multilocus molecular analysis targeting nr SSU , LSU tef1-α rpb1, rpb2 specimens, identified three novel species within Clavicipitaceae herein described as: Albacillium fuzhouense sp. nov., Conoideocrella gongyashanensis nov. Neoaraneomyces wuyishanensis well recently recorded, Metarhizium cicadae . Each new also distinguished its closest relatives by unique characteristics. Discussion discoveries enrich our understanding family contribute development control strategies
