Here we present first records of three moth fly species in the Czech Republic (Katamormia bezzii Salamanna, 1983, Panimerus goodi Vaillant & Withers, 1992 and Pneumia fonticola (Szabó, 1960)), increasing the total number of Czech moth fly species to 179. Katamormia bezzii represents the first finding outside of Italy, while P. goodi is only the second record outside of its type locality (Ireland), as is Peripsychoda zbytka Ježek, 2004 (Bohemia or.) and Pneumia kabelaki Omelková & Ježek, 2012 (Bílé Karpaty PLA). Jungiella (Psychocha) janiki Omelková & Ježek, 2017 has only been found at five sites (incl. the type locality) in the Bílé Karpaty Mts so far. The current number of species from the northwest part of the Czech Carpathians now totals 116. Altogether, 32 species were included in the national Red List of threatened invertebrates (Ježek 2005), with 23 species categorised as ‘nationally scarce’. Maximum alpha diversity was 61 species (71 as the sum of two seasons) at SKM OR 1 in the Skalická Morávka National Nature Monument (NNM), with maximum beta diversity also recorded at the Skalická Morávka NNM, with 82 species from three localities.
