Over the last two decades the molecular phylogeny and classification of Metarhizium has been widely studied. Despite these efforts to understand this enigmatic genus, the basal lineages in Metarhizium are still poorly resolved. In this study, a phylogenetic framework is reconstructed for the Clavicipitaceae focusing on Metarhizium through increased taxon-sampling using five genomic loci (SSU, LSU, tef, rpb1, rpb 2) and the barcode marker ITS rDNA. Multi-gene phylogenetic analyses and morphological characterisation of green-spored entomopathogenic Metarhizium isolates from Thailand and soil isolates of M. carneum and M. marquandii reveal their ecological, genetic and species diversity. Nineteen new species are recognised in the Metarhizium clade with narrow host ranges: two new species are found in the M. anisopliae complex – M. clavatum on Coleoptera larvae and M. sulphureum on Lepidoptera larvae; four new species are found in the M. flavoviride complex – M. biotecense and M. fusoideum on brown plant hoppers ( Hemiptera ), M. culicidarum on mosquitoes, M. nornnoi on Lepidoptera larvae; three new species M. megapomponiae, M. cicadae, M. niveum occur on cicadas; five new species M. candelabrum, M. cercopidarum, M. ellipsoideum, M. huainamdangense M. ovoidosporum occur on planthoppers, leafhoppers and froghoppers ( Hemiptera ); one new species M. eburneum on Lepidoptera pupae; and four new species M. phuwiangense, M. purpureum, M. purpureonigrum, M. flavum on Coleoptera . Of these 19 new species, seven produce a sexual morph ( M. clavatum, M. eburneum, M. flavum, M. phuwiangense, M. purpureonigrum, M. purpureum, and M. sulphureum ) and asexual morphs are found in the remaining new species and also in M. sulphureum, M. purpureonigrum and M. purpureum. Metarhizium blattodeae, M. koreanum and M. viridulum are new records for Thailand. An alternative neotype for Metarhizium anisopliae is proposed based on multi-gene and 5′ tef analyses showing that CBS 130.71 from Ukraine is more suitable, being from a much closer geographical location to Metchnikoff’s Metarhizium anisopliae. This isolate is distinct from the neotype of Metarhizium anisopliae var. anisopl...

“…In G. cebrennini and G. fusiformispora, it may also be difficult to discriminate them at first glance as the only distinguishing feature is the shape of their part-spores. These similiarities, and the occasional overlap in shape and size of morphological characters, were also demonstrated by in the Ophiocordyceps irangiensis and O. myrmecophila species complex, by Mongkolsamrit et al (2019) in Paraisaria phuwiangensis and P. yodhathaii, by Luangsaard et al (2018) in Ophiocordyceps spp. with superficial perithecia, and among termite pathogens in Ophiocordyceps.…”

“…Relative support for the branches was obtained from bootstrap analysis with 1,000 replicates. Bayesian analysis was performed according to Mongkolsamrit et al (2019) using MRBAYES v.3.2.7 ( Ronquist and Huelsenbeck 2003 ) on XSEDE via the online CIPRES Science gateway using SYM+G selected by MRMODELTEST 2.2 ( Nylander 2004 ) as the best nucleotide substitution model. Posterior probabilities were performed by Markov Chain Monte Carlo Sampling ( MCMC ) in which four chains were run for 5,000,000 generations with a tree sampling frequency of 100 and a burn-in of 10% of the total run.…”

Phylogeny- and morphology-based recognition of new species in the spider-parasitic genus Gibellula (Hypocreales, Cordycipitaceae) from Thailand

Thailand is known to be a part of what is called the Indo-Burma biodiversity hotspot, hosting a vast array of organisms across its diverse ecosystems. This is reflected by the increasing number of new species described over time, especially fungi. However, a very few fungal species from the specialized spider-parasitic genus Gibellula have ever been reported from this region. A survey of invertebrate-pathogenic fungi in Thailand over several decades has led to the discovery of a number of fungal specimens with affinities to this genus. Integration of morphological traits into multi-locus phylogenetic analysis uncovered four new species: G. cebrennini, G. fusiformispora, G. pigmentosinum, and G. scorpioides. All these appear to be exclusively linked with torrubiella-like sexual morphs with the presence of granulomanus-like asexual morph in G. pigmentosinum and G. cebrennini. A remarkably high host specificity of these new species towards their spider hosts was revealed, and for the first time, evidence is presented for manipulation of host behavior in G. scorpioides.

“…It was originally collected only in two occasions in Hakgala, Sri Lanka (Ceylon back in that time) with recent few records from Thailand (Luangsa-ard et al 2018). Another example of an Ophiocordyceps infecting a cockroach is O. blattarioides (= Paraisaria blattarioides -see Mongkolsamrit et al 2019). This species was described from Colombia with records in Belize and tropical lowlands in the Amazonian side of Andes region of Ecuador (Sanjuán et al 2015).…”

Entomopathogenic fungi are ubiquitous inhabitants of forests worldwide, remarkably in tropical regions. Among these fungi, one of the most abundant and diverse is the genus Ophiocordyceps. These fungi are particularly diverse and more commonly found parasitizing coleopteran, lepidopteran, hymenopteran and hemipteran insects. However, other insect orders are also parasitized by these fungi, for example the blattodeans (termites and cockroaches). Despite their ubiquity in nearly all environments insects occur, blattodeans are rarely found infected by filamentous fungi and thus, their ecology and evolutionary history remains obscure. In this study, we propose a new species of Ophiocordyceps infecting the social cockroaches Salganea esakii and S. taiwanensis, based on 16 years of collections and field observations, especially the Ryukyu Archipelago. We found a high degree of genetic similarity between specimens from different islands, infecting two Salganea species and that this relationship is ancient, likely not originated from a recent host jump. Furthermore, we found that Ophiocordyceps lineages infecting cockroaches evolved around the same time, at least twice, one from beetles and the other from termites. We have also investigated the evolutionary relationships between Ophiocordyceps and termites and present the phylogenetic placement of O. blattae for the first time.
