Abstrakt
The Hilara species (Diptera, Empididae) of Switzerland, with respect to the fauna of the Alps and other central European mountains. - Within the fauna of the Alpine region 118 Hilara species are recognized including some species which are not yet known from the region but may be expected. The species are keyed, and full distributional data are given for the Alps.
Eight new species are described: Hilara leukensis sp. n., H. luteihalterata sp. n., H. planti sp. n. and H. crossleyi sp. n. from the Swiss Alps, H. brevistriata sp. n. from the Swiss and Austrian Alps, H. parvimaior sp. n. from the Swiss and Italian Alps, H. sirbitzmatrona sp. n. from the Austrian Alps, and H. polleti sp. n. from the Bulgarian Rhodope Mts. Several further species are fully redescribed and illustrated for the first time (H. cinereomicans Strobl, H. sartor Becker, H. tiefii Strobl, H. tanychira Strobl, H. dimidiata Strobl, H. simplicipes Strobl, H. calinota.
Collin, H. pruinosa Wiedemann in Meigen, H. hystrix Strobl, H. pectinipes Strobl), and the females of H. helvetica Chvala and H. zermattensis Chvala are described here for the first time. A lectotype is designated for H. pilosopectinata Strobl.
The following new synonymies are proposed: Hilara maior Strobl, 1910 (= Hilara tatra Niesiolowski, 1991) and Hilara tyrolensis Strobl, 1892 (= H. miriptera Straka, 1976). The synonymy of Hilara longesetosa Strobl, 1910 with H. pilosopectinata Strobl, 1892 is explained.
Hilara longicornis Strobl, 1894, described and still known only from the Hungarian lowlands, is fully redescribed and its correct classification within the genus Hilara is discussed in the section "additional species". The same applies to Hilara flavocoxa Straka, 1976, a species known only from a single locality in highlands of central Slovakia
