First Central European record of the fungusProlixandromyces triandrusSantam. (Ascomycota: Laboulbeniales), a parasite of veliid bugs (Heteroptera: Veliidae), with notes on its biology and DNA barcoding

A new distribution record for Prolixandromyces triandrus Santam. (Ascomycota: Laboulbeniales) is presented from the Bukk Mountains in northeastern Hungary, from the host species Velia (Plesiovelia) saulii Tamanini, 1947 (Heteroptera: Veliidae). Hitherto, this fungal parasite had only been observed in the western Mediterranean region and the Macaronesia Archipelago. Prolixandromyces. triandrus seems to be abundant in the reported Hungarian host population. Additionally, ribosomal DNA barcodes for this fungal species are also presented. Incidence of the parasite and potential of the molecular investigations of host-parasite relationships of this ectoparasitic fungus is discussed. A brief review is given of known hosts of P. triandrus and of Laboulbeniales from aquatic/semiaquatic insect hosts in Hungary.
