“…4, Table 3). Our phylogenetic analysis is in accordance with previously published Ophiocordyceps topology (Quandt et al 2014, Sanjuán et al 2015, Araújo et al 2018, Tasanathai et al 2019). All O.salganeicola specimens we collected, from different parts of Japan and infecting two species of Salganea, clustered together as a single species with considerably high degree of genetic similarity with a long branch (Fig.…”

“…We currently only know 10 species infecting termites, i.e. O. bispora -(Sti er 1941); O. octospora - (Blackwell and Gilbertson 1981); O. communis - (Sung et al 2007); O. asiatica, O. brunneirubra, O. khokpasiensis, O. mosingtoensis, O. pseudocommunis, O. pseudorhizoidea and O. termiticola - (Tasanathai et al 2019). Furthermore, there are only three species described infecting cockroaches, i.e.…”

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.

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.

“…In 2019, animal‐associated fungi from different lineages were described including forty‐eight new species of animal‐associated Sordariomycetes (Figure 5). Among these are eight species of Ophiocordyceps from cicada nymphs and termites in Thailand (Crous, Schumacher, et al, 2019; Crous, Wingfield, et al, 2019; Tasanathai et al, 2019) and seven species of ambrosia fungi in the genera Ambrosiella , Toshionella , and Wolfgangiella (Mayers et al, 2019), which are cultivars of ambrosia beetles, depending on the beetles’ fungus‐carrying organs (mycangia) for dispersal.…”
