Čas. Slez. Muz. Opava (A), 61: 85-90, Abstract: New data about the distribution of selected species of family Heleomyzidae (Diptera) in the Czech Republic and Slovakia are given. Scoliocentra (Leriola) nigrinervis (Wahlgren, 1918) and Suillia cepelaki Martinek, 1985 are recorded for the first time from the Czech Republic and Orbellia cuniculorum Robineau-Desvoidy, 1830 is a new addition to the fauna of Slovakia. New records of three rare species of the genus Suillia, viz. S. variegata (Loew, 1862), S. gigantea (Meigen, 1830) and S. oxyphora (Mik, 1900) from the Czech Republic are presented. The habitat association and the attraction of adults of some species to bait used in traps are discussed. Key words: Diptera, Heleomyzidae, new records, distribution, habitat, bait attraction, Czech Republic, Slovakia Introduction The family Heleomyzidae is relatively well studied in the Czech Republic and Slovakia: the most recent checklist (Dvořáková 2009) comprises as many as 84 species known from the Czech Republic (82 in Bohemia, 74 in Moravia) and 74 species from Slovakia. The recent collecting effort of a number Czech dipterists, who used various trapping methods (see below) in a number of localities yielded an extensive material of Diptera including Heleomyzidae. In the present paper some of the most interesting results are given based on the study of this recently collected Heleomyzid material but also on the revision of some formerly recorded species, with new additions to the fauna of the Czech Republic and Slovakia and records of species formerly considered rare in the Czech Republic. Because the majority of the specimens recorded in this paper was collected by means of baited traps the advantage of this method for collecting Heleomyzidae is discussed. Material and methods The material examined is deposited in the following collections: JMB Collection of Dr. J. Máca, Ph.D., České Budějovice; JPL collection of J. Preisler, Liberec; KDM Collection of Mgr. K. Dvořáková, Mariánské Lázně; KMVC Krajské muzeum východních Čech, Hradec Králové; MBP collection of Prof. Dr. M. Barták, CSc., Praha; MMML Městské muzeum, Mariánské Lázně; SMLC Severočeské muzeum Liberec; SMOC Slezské zemské muzeum, Opava (all Czech Republic). All specimens were identified by senior author, unless mentioned otherwise. The collecting methods used are abbreviated as follows: BT beer traps, GT ground (pitfall) traps, MT Malaise traps, PT protein-meat traps, SW sweeping, YPT yellow pan traps. The nomenclature follows that used by Wożnica (2011) in the Fauna Europaea database. 85

2 New records of Heleomyzidae from the Czech Republic and Slovakia Scoliocentra (Leriola) nigrinervis (Wahlgren, 1918) Material examined: CZECH REPUBLIC: Bohemia occ., Šumava Mts, Červená near Kašperské hory, Šafářův vršek hill (6847/6947), 850 m a.s.l., rock debris, GT (cheese),18.ix vi.2012, 1 1, P. Vonička & P. Moravec leg. (JPL). S. nigrinervis obviously has a Boreo-alpine distribution occurring only in mountains at more southern latitudes and has usually been caught in winter and early spring on snow during the thaw (Martinek 1980; Woznica 1993). Also the specimens examined were caught in pitfall traps during winter or early spring. The species can inhabit subterranean habitats because these pitfall traps were situated deep among stones in the montane slope scree (Fig. 1). The species is widespread in the Palaearctic Region but has been recorded very scarcely in Central Europe. The previous records are summarized by Wożnica (2011) as follows: Bulgaria, Estonia, Finland, Germany, Kazakhstan, Mongolia, Norway, Poland, Russia (CET, NET), Slovakia, Sweden. First record for the Czech Republic. Orbellia cuniculorum Robineau-Desvoidy, 1830 Material examined: SLOVAKIA: SW Slovakia: Láb pr. Malacky, 7.xii.1975, 1, M. Kozánek lgt. (MBP). This specimen was recorded from Slovakia by Martinek (1984a) as Orbellia hiemalis (Loew, 1862). During the revision of the material of Heleomyzidae deposited in the collection of M. Barták (MBP) it was found by the senior author to be misidentified. O. cuniculorum is a rare species which has hitherto been only known from France, Germany, Hungary, Lithuania, Poland and Spain (Wożnica 2011). This is the first record from Slovakia. Suillia cepelaki Martinek, 1985 Material examined: CZECH REPUBLIC: SE Moravia: Bílé Karpaty Protected Landscape Area, Nová Lhota, Vápenky Hubertova chata (hut) (7171b4), N, E, 563 m, beech forest, slope spring area, MT, 22.ix.2005, 3 ; same, Strání, Javorina NNReserve, peak (7172a3), N, E, 935 m, montane matgrass meadow at forest margin, MT, 5.viii.2009, 1, all Chvojka, Ježek & Macek leg. (JPL). SLOVAKIA: Korytnica, Biskup, 20.iv.1975, 15 2 paratypes, J. Čepelák leg., V. Martinek det (SMOC). This rare species has hitherto been known only from type specimens found in two localities in western and central Slovakia (Malé Karpaty Mts: Dolany; Nízke Tatry Mts: Korytnica-Biskup), as listed in the original description by Martinek (1985b). The above Moravian specimens were identified by comparison with male paratypes deposited in SMOC. First record for the Czech Republic (second after the description) and a new westernmost distribution limit of the species. Martinek (1985b) suggested that this species possibly develops in wood garlic (Allium ursinum). The association of this species with this plant is indicated also by the presence of wood garlic in both new localities in the Bílé Karpaty Mts. According to Martinek (1985b) S. cepelaki is very similar to S. univittata (von Roser, 1840), a phytophagous species developing in bulbs of woodland Liliaceae but also in garlic, leek and onion (Papp 1981) which can even be a pest in these cultivated plants because young larvae are feeding on sprouting leaves. Therefore, S. cepelaki is supposed to similarly develop in Allium ursinum. The seasonal occurrence of adults in early spring (Martinek 1985b) and autumn (new records) suggests that the species is probably univoltine, with adults emerging already in the autumn and overwintering, and females ovipositing in early spring on sprouting wood garlic. 86

3 New data about the distribution of three Suillia species in the Czech Republic The three species listed below were formerly considered very rare in the Czech Republic. The following records originate either from the personally (J. Preisler) collected material in the years or were acquired during the identification of specimens obtained by other dipterists, to whom the particular records are attributed. In addition, several unpublished records from the collection of M. Barták (MBP) and K. Dvořáková (KDM) are also presented.

(NMPC). A mycophagous species, hitherto considered very rare in the Czech Republic. Martinek (2001a) predicted its spreading from warm southern lowlands to northern parts of the country. It is generally common in southern Europe but has also been recorded more northerly, viz. from Ireland, G. Britain (up to Scotland), Belgium, The Netherlands, Denmark and southern Sweden. Most specimens examined were collected by means of beer traps thus, fermented beer appears to be particularly attractive to adults of this species.

Palaearctic, mycetophagous species known from Albania, Andorra, Austria, Britain, Bulgaria, Czech Republic, Germany, Hungary, Italy, Poland, Romania, Slovakia, Spain, Switzerland, Ukraine and the former Yugoslavia (Wożnica 2011), hitherto very rarely recorded from the Czech Republic (see published records above). Discussion and conclusions The use of baited traps essentially changed the previous view about the frequency of records of some of the rare species of the family Heleomyzidae. By means of bait trapping 88

5 can frequently be captured even the species which are recorded only occasionally using classical collecting methods (sweeping, Malaise traps, yellow pan traps). For exemple, the meat-baited traps frequently (and often abundantly) attract species of the genera Oldenbergiella Czerny, 1924 (Roháček 1997; Preisler & Dvořáková 2009), Neoleria Malloch, 1919, Heleomyza Fallén, 1810, Scoliocentra Loew, 1862; Tephrochlamys Loew, 1862 and, surprisingly enough, also Suillia flavifrons (Zetterstedt, 1838) formerly considered mycophagous (Preisler & Dvořáková 2009). In the fermenting (beer, syrup baited) traps the mycophagous species of the genus Suillia are found, sometimes in large quantity (Dvořáková 2008; Preisler & Dvořáková 2009). This fact can also be demonstrated by the above records of three Suillia species previously considered rare in the Czech Republic of which series of specimens have been caught by the senior author and K. Dvořáková by means of the beer traps. Fig. 1: Habitat of Scoliocentra nigrinervis (Wahlgren, 1918), a montane scree on slope of the Šafářův vršek hill in the Šumava Mts. Photo by P. Vonička.

Fauna Europaea version 2.4, Nové faunistické nálezy druhů čeledi Heleomyzidae (Diptera) z České republika a Slovenska, s poznámkami k rozšíření tří vzácných druhů rodu Suillia Jsou prezentovány nové údaje o výskytu vybraných druhů čeledi Heleomyzidae (Diptera) v České republice a na Slovensku. Scoliocentra (Leriola) nigrinervis (Wahlgren, 1918) a Suillia cepelaki Martinek, 1985 jsou poprvé zaznamenány na území České republiky a Orbellia cuniculorum Robineau-Desvoidy 1830 je novým druhem pro faunu Slovenska. Je podán přehled nových nálezů tří vzácných druhů rodu Suillia, viz. S. variegata (Loew, 1862), S. gigantea (Meigen, 1830) and S. oxyphora (Mik, 1900) z území České republiky. U některých druhů jsou diskutovány jejich vazby na biotopy a hodnocena atraktivita návnad (zejména zkvašeného piva) používaných v pastích k odchytu dospělých jedinců.
