Abstract
The biodiversity of non-biting moth flies (Diptera: Psychodidae) in Slovakia is presented. A total of 69 species are recorded, of which 10 are new for the country: Panimerus goetghebueri (Tonnoir, 1919), Feuerborniella obscura (Tonnoir, 1919), Philosepedon (Philosepedon) dumosum Omelková & Ježek, 2012, P. (P.) nickerli Ježek, 1997, P. (P.) perdecorum Omelková & Ježek, 2012, P. (Philothreticus) soljani Krek, 1971, Logima surcoufi (Tonnoir, 1922) comb. n. (originally described as Psychoda), Berdeniella caprai Salamanna & Sarà, 1979, B. lucasii (Satchell, 1955) – also newly recorded for Europe; and Tonnoiriella obtusa (Tonnoir, 1919). Four species are classified as critically endangered: Promormia silesiensis Ježek, 1983, Parajungiella ellisi (Withers, 1987), Philosepedon (Trichosepedon) balkanicum Krek, 1971, and Saraiella rotunda (Krek, 1970). Five species are considered endangered: Promormia eatoni (Tonnoir, 1940), Panimerus goetghebueri (Tonnoir, 1919), Pericoma (Pericoma) exquisita Eaton, 1893, Pneumia stammeri (Jung, 1956), and Ulomyia vaseki Ježek, 2002. Three species are classified as vulnerable: Parajungiella prikryli Ježek, 1999, Philosepedon (Philosepedon) nickerli Ježek, 1997, and Threticus silvaticus Ježek, 1985. In addition, 13 species are currently considered nationally scarce (NS), with no assessed conservation status: Philosepedon (Philosepedon) dumosum Omelková & Ježek, 2012, P. (P.) perdecorum Omelková & Ježek, 2012, P. (Philothreticus) soljani Krek, 1971, Threticus negrobovi Vaillant, 1972, Apsycha pusilla (Tonnoir, 1922), Logima surcoufi (Tonnoir, 1922), Berdeniella caprai Salamanna & Sarà, 1979, B. lucasii (Satchell, 1955), Berdeniella vimmeri Ježek, 1995, Clytocerus (Boreoclytocerus) longicorniculatus Krek, 1987, C. (B.) splendidus Ježek & Hájek, 2007, Pericoma (Pericoma) tatrica Szabó, 1960, and Tonnoiriella obtusa (Tonnoir, 1919). Establishing a robust faunal and taxonomic foundation is essential for understanding and protecting biodiversity. This knowledge can directly support the conservation of numerous species (25 in this study) and guide the management of their habitats, which are often threatened by the development of large-scale mountain tourism infrastructure. This study also provides a preliminary proposal for the inclusion of Slovak non-biting moth flies (Diptera: Psychodidae) on the national list of threatened species.
