Bibionomorph gnats (Diptera: Nematocera) collected from Lažany village, Slovakia.

We present records of 103 fly species from six families of Bibionomorpha (namely: Anisopodidae, Ditomyiidae, Bolitophilidae, Diadocidiidae, Keroplatidae, and Mycetophilidae) collected by a single Malaise trap in an Eastern Slovakia locality during the vegetation period in 2023. Data on five species, viz., Mycomya (Neomycomya) fimbriata (Meigen, 1818), Synapha fasciata Meigen, 1818, Cordyla pusilla Edwards, 1925, Mycetophila freyi Lundstrom, 1909, and Sceptonia tenuis Edwards, 1925 (all Mycetophilidae) represent the first records for the fauna of Slovakia, and habitus photographs of these species have been provided. A very rare Central European species – Neoclastobasis draskovitsae Matile, 1978 – has also been recorded and photographed. [ABSTRACT FROM AUTHOR]
