“…Similarly to previous studies [39,48], we confirm the high specificity of the two fungal parasites, A. eucampsipodae and A. nycteribiae, towards N. schmidlii and P. conspicua, respectively. Infection prevalence and intensity strongly differed depending on the fly/fungi associations.…”

Background: Parasites are able to alter numerous aspects of their hosts' life history, behaviour and distribution. One central question in parasitology is to determine the degree of impact that parasites have on their hosts. Laboulbeniales (Fungi: Ascomycota) are ectoparasitic fungi of arthropods. Even though these fungi are widely distributed, little is known about their ecology and their possible physiological effects on their hosts. We used a highly specific bat fly-fungi association to assess the effect of these fungal parasites on their dipteran hosts. Methods:We collected bat flies (Diptera: Nycteribiidae) belonging to two species, Nycteribia schmidlii and Penicillidia conspicua from their bat host Miniopterus schreibersii (Chiroptera: Miniopteridae). We experimentally tested the effect of infection on the lifespan of bat flies. Results:The prevalence of Laboulbeniales fungi was 17.9% in N. schmidlii and 64.8% in P. conspicua. Two fungi species were identified, Arthrorhynchus eucampsipodae and A. nycteribiae, both showing strict host specificity with N. schmidlii and P. conspicua, respectively. We found that fungal infection reduced by half the survival rate of P. conspicua regardless of sex, whereas N. schmidlii was not affected by the infection. Moreover, the intensity of infection showed negative correlation with the lifespan of P. conspicua. Conclusions:To our knowledge, this is the first indication that fungal infection can alter bat fly survival and thus may play a significant role in the population dynamics of these bat ectoparasites.

“…Our complete dataset, prior to excluding specimens and partitioning (), was composed of 2,599 bats and 7,949 bat flies, of which 363 (= 4.6%) were infected by Laboulbeniales. Seven bat species were included in our final temperate dataset (Haelewaters et al., 2017a; Szentiványi et al., ). The most abundantly parasitized bat species was Miniopterus schreibersii ( n = 414), followed by Myotis daubentonii ( n = 206).…”

The aim of this study was to explore the diversity of ectoparasitic fungi (Ascomycota, Laboulbeniales) that use bat flies (Diptera, Hippoboscoidea) as hosts. Bat flies themselves live as ectoparasites on the fur and wing membranes of bats (Mammalia, Chiroptera); hence this is a tripartite parasite system. Here, we collected bats, bat flies, and Laboulbeniales, and conducted phylogenetic analyses of Laboulbeniales to contrast morphology with ribosomal sequence data. Parasitism of bat flies by Laboulbeniales arose at least three times independently, once in the Eastern Hemisphere (Arthrorhynchus) and twice in the Western Hemisphere (Gloeandromyces, Nycteromyces). We hypothesize that the genera Arthrorhynchus and Nycteromyces evolved independently from lineages of ectoparasites of true bugs (Hemiptera). We assessed phylogenetic diversity of the genus Gloeandromyces by considering the LSU rDNA region. Phenotypic plasticity and position‐induced morphological adaptations go hand in hand. Different morphotypes belong to the same phylogenetic species. Two species, G. pageanus and G. streblae, show divergence by host utilization. In our assessment of coevolution, we only observe congruence between the Old World clades of bat flies and Laboulbeniales. The other associations are the result of the roosting ecology of the bat hosts. This study has considerably increased our knowledge about bats and their associated ectoparasites and shown the necessity of including molecular data in Laboulbeniales taxonomy.

“…The genus Dimeromyces, on the other hand, is one of the largest genera of Laboulbeniales encompassing 115 species, of which only two are found on bat flies (Rossi et al 2015. In the last few years, studies on bat fly-associated Laboulbeniales have focused on extensive surveying, taxonomy (description of species), host specificity, tripartite association networks, phylogenetic placement of bat fly-specific genera, and morphological versus molecular diversity of Gloeandromyces (Haelewaters et al 2017a, b, 2018b, Szentiványi et al 2018, Walker et al 2018.…”

In this paper, new species and formae of the genus Gloeandromyces (Ascomycota, Laboulbeniales) are described and illustrated. These are: Gloeandromyces dickii sp. nov. on Trichobius joblingi from Nicaragua and Panama; G. pageanus f. alarum f. nov. on Tri. joblingi from Panama; G. pageanus f. polymorphus f. nov. on Tri. dugesioides and Tri. joblingi from Panama and Trinidad; and G. streblae f. sigmomorphus f. nov. on Tri. joblingi from Panama. Gloeandromyces pageanus on Tri. dugesioides from Panama as described in Nova Hedwigia 105 (2017) is referred to as G. pageanus f. pageanus. Support for these descriptions of species and formae comes from phylogenetic reconstruction of the large subunit ribosomal DNA and from the application of species delimitation methods (ABGD, bPTP, GMYC). Host specialization results in phylogenetic segregation by host species in both G. pageanus and G. streblae and this may represent a case of incipient speciation. A second mechanism driving diversity involves position-induced morphological adaptations, leading to the peculiar morphotypes that are associated to growing on a particular position of the integument (G. pageanus f. alarum, G. streblae f. sigmomorphus). 27 appendage, cells VI and VII, and perithecial projection and bumps usually darker. Cell I straight, broadening upwards, especially at anterior side, 3.4-4.1× longer than broad, carrying cells II and VI. Cell II trapezoidal, slightly broader than long, obliquely positioned. Cell III broadly triangular, slightly longer than broad.Basal cell of appendage pentagonal, with parallel anterior and posterior margins, carrying two short (up to 25 µm) branches of dichotomously dividing cells, outer suprabasal cell always higher than inner one, final cells antheridial. Cell VI broader than long, obliquely positioned, broadly lens-shaped or flattened between
