Ulomyia annulata annulata (Tonnoir, 1919)

Published records. Devět Mlýnů ( JEŽEK et al. 2005).

Material examined. Chvalovice, Daníž brook (6), J, vi., Inv. No. 8362; Olbramkostel, Vracovice, Vracovický rybník pond (55), J, ix., Inv. No. 6034.

Comment. So far known from Belgium, Germany, Czech Republic, Slovakia, Lithuania and Russia (western Siberia – Novosibirsk region; another subspecies, U. a. chimganensis Ježek, 1997 was described from Uzbekistan). It inhabits shaded but sometimes also unshaded habitats with decaying organic matter, e.g. ponds, water reservoirs, swamps, rills and wet meadows.

Comment. Generally one of the most common European species, widely distributed, known from throughout nearly the whole of Europe, although records from eastern Europe have been scarce so far (e.g. Lithuania). It occurs from lowlands to mountains in mosses in running water habitats with decaying organic matter, spring areas on slopes, banks of streams and brooks, outlets of ponds, cut-offs of rivers, marshes, swampy meadows and forest pools.

Summary of the records. From a biogeographical point of view, 50 species found in this survey include mostly European species (28 species, including 3 Central European species). The remaining species are Eurosiberian (8), Holarctic (6), Submediterranean (2) and Cosmopolitan (3) (Table 2 and remarks to individual species).

Five of the fifty species recorded were the most frequently collected species in the study area. Pneumia nubila and P. trivialis were found at 36 and 33 localities, respectively. They were followed by Parajungiella longicornis with 18 records, Clytocerus ocellaris with 17 records, and Pericoma fallax with 16 records. In contrast, altogether 19 species were collected at a single locality: Sycorax silacea , Trichomyia hardeggensis sp. nov., T. urbica , Promormia eatoni , Jungiella acuminata , J. laminata , Parajungiella consors , P. ellisi , Paramormia polyascoidea , Philosepedon dumosum , P. humerale , Threticus incurvus , Logima zetterstedti , Psychoda phalaenoides , Psychodocha gemina , Psychodula minuta , Tinearia lativentris , Pneumia crispi and Tonnoiriella sieberti .

The highest number of psychodid species was recorded from the following localities: Čížov, rills (15) (13 species); Vranov nad Dyjí, Braitava (4) (11 species); Horní Břečkov, pond (26) (10 species); Mašovice, Andělský Mlýn (1) (9 species); Vranov nad Dyjí, Lesná (31) (9 species); Podmolí, Žlebský potok brook (37) (9 species); Čížov, marshes (12) (8 species); and Popice, pond (38) (8 species). Five localities hosted 7 species and 10 localities 6 species. A single psychodid species was collected at 8 localities.

Species richness of moth flies of the Podyjí National Park. Our knowledge on moth flies of the Podyjí National Park is fragmentary as this area has been overlooked by dipterologists in the past. The only available records are recent ( JEŽEK 2003, JEŽEK et al. 2005, OMELKOVÁ & JEŽEK 2012b) and they document the occurrence of 65 species in the area. A total of 50 species (including 2 subspecies) of 25 genera collected at 63 localities were recorded in the present study. Comparing with the earlier data ( JEŽEK et al. 2005), altogether 11 species, including Trichomyia hardeggensis sp. nov., were previously not found and are formally new for the fauna of the Podyjí NP and its environs (see Table 2 for the list of these species). In contrast, 25 species were not found at present study (Table 2). Together with earlier data ( JEŽEK et al. 2005), 75 species are known from the Podyjí NP and its vicinity.

The description of a new species Trichomyia hardeggensis sp. nov., together with additional new records of Psychomormia vaillanti (Wagner, 1977) , Apsycha pusilla (Tonnoir, 1922) and Clogmia albipunctata (Williston, 1893) from Moravia (JEŽEK et al. 2012, JEŽEK & OMELKOVÁ 2012) and the descriptions of Philosepedon (Philosepedon) dumosum Omelková & Ježek, 2012 , P. (P.) perdecorum Omelková & Ježek, 2012 and Pneumia kabelaki Omelková & Ježek, 2012 from both Bohemia and Moravia ( OMELKOVÁ & JEŽEK 2012a,b), increased the number of moth flies known from the Czech Republic to 173 (141 species in Bohemia and 152 species in Moravia) (cf. JEŽEK 2009). Seventy-five species found in the Podyjí NP (75 species) represent 43.4 % of the psychodid fauna of the Czech Republic and about half (49.3 %) of all species known from Moravia. A comparable number of species was recorded in the mountains at the northern frontier of the Czech Republic: Jeseníky Mts. – 78 species collected at 226 localities ( JEŽEK 2006a), Jizerské hory Mts. and Frýdlant region – 78 species collected at 79 localities ( JEŽEK et al. 2008) and Orlické hory Mts. – 66 species collected at 145 localities ( JEŽEK & HÁJEK 2007). A higher number of species collected at a similar number of localities as in the Podyjí NP was found in the Bílé Karpaty PLA, where 107 species were recorded from 78 localities (JEŽEK & OMELKOVÁ 2012). A lower number of species are known from regions where Psychodidae were collected at a comparably lower number of localities: Pálava Biosphere Reserve of UNESCO – 51 species from 41 localities ( JEŽEK 1999a), Kokořínsko PLA – 39 species from 36 localities ( JEŽEK 2006b), Krkonoše Mts. (high altitudes) – 23 species from 15 localities ( JEŽEK et al. 2010), and industrial region of Duchcov and Bílina – 47 species from 7 localities ( JEŽEK & BARTÁK 2000).

Altogether 10 species classified in the national Red List of threatened invertebrates (JEŽEK 2005) were recorded in the Podyjí NP (Table 2). Six of them are regarded as critically endangered: Trichomyia urbica , Promormia silesiensis , Jungiella laminata , Parajungiella ellisi , P. pseudolongicornis and Psycmera integella . Four species have been classified as endangered: Promormia eatoni , Threticus incurvus , Pneumia crispi and Tonnoiriella sieberti . Furthermore, two species, namely Trichomyia hardeggensis sp. nov. and Philosepedon dumosum , can be considered to be nationally scarce species based on present knowledge of their distribution in the Czech Republic. They represent new and remarkable records, not included in the Red List so far.
