New Distributional Data for the Rare Polish Empidid Flies (Empididae: Hemerodromiinae, Clinocerinae) in the Pieniny Mountains with Notes on Ecology and Phenology

Abstract

A study of Hemerodromiinae and Clinocerinae (Diptera: Empididae) in the Pieniny Mts. (Southern Poland) recorded eleven rare species. Two of them are rediscovered in Poland for the first time since 19th century: Chelifera aperticauda Collin, 1927 and Clinocera fontinalis (Haliday, 1833). Six other species are rare or recently regarded as rare in Poland: Chelifera subangusta Collin, 1927, C. pectinicauda Collin, 1927, Hemerodromia oratoria (Fallén,1815), Kowarzia plectrum Mik, 1880, Wiedemannia jazdzewskii NiesioÅ‚owski, 1987, W. thienemanni Wagner, 1982. Three species: Chelifera angusta Collin, 1927, Hemerodromia melangyna Collin, 1927 and Wiedemannia phantasma (Mik, 1880) are in Poland confined to the Pieniny Mts. with no records from elsewhere in the country. Drawings of some male genital structures as well as short ecological and phenological notes are presented.
