The fauna of the opomyzoid families Clusiidae, Acartophthalmidae, Anthomyzidae, Opomyzidae, Stenomicridae, Periscelididae, Asteiidae (Diptera) in the Gemer area (Central Slovakia). – Čas. Slez. Muz. Opava (A): 61: 97-111, 2012.

Abstract. A synopsis of the fauna of seven families of (Diptera) in the Gemer area (Slovakia) is given. Clusiidae (8 ), Acartophthalmidae (2 species), Anthomyzidae (9 species), Opomyzidae (8 species), Stenomicridae (1 species), Periscelididae (1 species) and Asteiidae (5 species) are treated on the basis of previously published records and material examined. Each species is listed with comments about its general distribution, and faunistic and/or nature conservation importance. Podocera soniae (Merz & Roháček, 2005) (Stenomicridae) is the most interesting species because it was originally partly described from specimens (paratypes) discovered in the area. Other significant faunal elements include tigrina (Fallén, 1820), caledonicus (Collin, 1912), Hendelia beckeri Czerny, 1903, (Clusiidae) and Leiomyza curvinervis (Zetterstedt, 1838) (Asteiidae), all endangered or vulnerable species associated with well-preserved forests, and neglecta Collin, 1944, A. paraneglecta Elberg, 1968 (Anthomyzidae), apicalis (Meigen, 1830), G. hackmani Nartshuk, 1984, vulnerable species of wetland and grassland habitats.

Introduction

The majority of species of the opomyzoid acalyptrate families dealt with in this contribution were formerly recorded from the Gemer area. The Clusiidae from this territory were treated within Rohá ček’s (1995a) revision of the Czech and Slovak representatives of the ; similarly Anthomyzidae were recorded from the area by Rohá ček (1983, 1986a), Opomyzidae by Martinek (1976, 1984, 1985, 1986) and Martinek & Mocek (1995), Stenomicridae by Rohá ček (1983), Periscelididae by Máca (1986) and Rohá ček (1987) and Asteiidae by Rohá ček (1985, 1986b). Thus, only Acartophthalmidae are reported here from the Gemer area for the first time. The material sources for records published in the above papers originate from the collecting efforts by V. Zeman (who collected in the area in 1956), R. Rozkošný (in 1968), V. Martinek (in 1971), M. Kozánek and J. Máca (both in 1979), B. Mocek (in 1985) but predominantly J. Rohá ček (in 1980-1984). Additional recent material from the Gemer territory has been obtained by J. Šev čík in 2008-2012 (besides the netted material also including specimens from his Malaise traps in the localities of the Muránska planina Mts), by Ľ. Vidli čka (a few specimens from Malaise trap operated in Paseky nr. Tisovec in 2001), J. Máca (from single collecting trip in 2008) and by the author (from collecting trips in 2010-2012). This recently acquired material not only significantly contributed to the knowledge of the hitherto poorly studied Muránska planina National Park but also added records of several rare or otherwise important species formerly unknown from the whole of the Gemer region. The present study of opomyzoid belongs to a series of papers devoted to Diptera of the Gemer area (cf. Šev čík & Kurina 2011a,b; Roháček & Šev čík 2011; Rohá ček 2011; Šev čík 2011).

Material and methods

The present account of species of the above opomyzoid families in the Gemer area is based on critical review of all published records, supplemented by data obtained from the material collected recently in this

97

territory, identified by the author and external specialists and deposited in SMOC (unless mentioned otherwise). The nomenclature used here follows the most recent Checklist of Diptera of the Czech Republic and Slovakia, electronic version 2 (see Jedli čka et al. 2009). Species significant from the biogeographical, ecological or nature conservation point of view are marked by “*” preceding the species’ name. Abbreviations used in text: MT = Malaise trap, SMOC = Slezské zemské muzeum, Opava, Czech Republic.

Study area

The Gemer area is here understood as the territory of three national parks in central Slovakia – Muránska planina National Park (= NP), Slovenský raj NP and Slovenský kras NP. A part of the material presented in this study was collected within the framework of the All Taxa Inventories project (ATBI, see www.atbi.eu ) organized by Workpackage 7 (WP7) of the “European Distributed Institute of ” (EDIT, see www.e-taxonomy.eu ). All three national parks represent well-preserved karst areas with both montane and thermophilous species included, including several endemic. The results of the species inventory within the ATBI project are available at http://www.atbi.eu/gemer/ . Three Malaise traps were operated in the area – one at Fabova ho ľa Mt. in 2009, the second in the Hrdzavá dolina valley in 2010 and the third in Po ľudnica res. in 2011. For more detail see Šev čík & Kurina (2011a). In 2012 two additional Malaise traps were operated, one at the top plateau of Šiance res. (48°46'11''N, 20°04'14''E, 1000 m), the other near Muránska Lehota, in the Lehotský potok valley (48°42'58''N, 20°00'16''E, 455 m).

Synopsis of species

CLUSIIDAE

This small acalyptrate family includes only 14 species from Europe and adjacent island areas (Rohá ček & Merz 2007), 9 of which have been recorded from Slovakia (Rohá ček 2009b). Species of Clusiidae preferentially live in forests with a rich supply of dead wood because their larvae develop in decaying wood of fallen trunks and stumps; adults can be observed sitting or walking on dead tree trunks. No information about Clusiidae had been published from the Gemer area prior to Rohá ček (1995a). In the latter paper all available material of the family from the whole of Slovakia was revised, including also specimens from the Gemer area (largely those collected in the area by the author in years 1980-1984) and 5 species were recorded. These formerly published records are reviewed here and supplemented by new data obtained thanks to the collecting efforts by J. Šev čík, J. Rohá ček and J. Máca in 2008-2012. Altogether 8 species of Clusiidae are now known from the territory under study.

Remarks: A European species (formerly treated in Paraclusia , synonymized with Clusia by Lonsdale & Marshall 2008) associated with old forests with large dead stumps of beech, elm or oak, rarely other deciduous trees. It is treated as data deficient (DD) species in the Slovak red list of Diptera (Jedlička & Stloukalová 2001) and considered vulnerable (VU) in the Czech Republic (Rohá ček 2005a). Considering its frequency it can be considered a very characteristic species in beech (and mixed) forests (Fig. 6) of the Muránska planina NP. Its abundant occurrence on stumps (and fallen trunk) of Acer pseudoplatanus recorded in the Šiance reserve (only 8 specimens captured, some 15 more observed) is to be particularly noted because of the quite unusual tree species.

Remarks: A temperate and North European woodland species. Formerly, it has only been recorded from the Cho čské vrchy Mts (Rohá ček 1995a) and Po ľana Mts (Rohá ček 2009k) in Slovakia and is considered the rarest species of Clusiidae in this country. It seems to prefer montane forests in Central Europe and was treated as endangered (EN) in the Czech Republic (Rohá ček 2005a).

Clusiodes geomyzinus (Fallén, 1823) Material: Muránska planina NP, Fabova ho ľa res., MT, 15.v.-16.vi.2009, 1 ♂1♀, 16.vi.-25.viii.2009, 1 ♂, J. Šev čík leg. (SMOC). Remarks: A Palaearctic species restricted to northern and temperate belts. It is uncommon in Slovakia, preferably occurring in natural forests (Rohá ček 1995a). There is no previous record from the Gemer area.

Clusiodes pictipes (Zetterstedt, 1855) Material: Muránska planina NP, Muránska Lehota env., MT, 24.v.-22.vi.2012, 1 ♂, J. Rohá ček & J. Šev čík leg. (SMOC). Remarks: This North and Central European species seems to prefer old beech or beech- forests. It was treated as a data deficient (DD) species in the Slovak red list of Diptera (Jedli čka & Stloukalová 2001). Although it is locally common in the Carpathians the species has not been recorded from the Gemer region up to the present.

Remarks: A Palaearctic species but restricted to northern and temperate areas. It occurs relatively frequently in Slovakia, particularly in submontane warm forests (Rohá ček 1995a) but was treated as a data deficient (DD) species in the Slovak red list of Diptera (Jedli čka & Stloukalová 2001).

ACARTOPHTHALMIDAE

A minute acalyptrate family with only one Czerny, 1902 and 4 extant species, 3 of which occur in Europe and were also recorded from Slovakia (Rohá ček 2009c). The relationships of the family is under discussion (most recently considered to be a member of , cf. Buck 2006) but is here retained in Opomyzoidea following previous convention. Adults of Acartophthalmus species are minute dark flies (Fig. 1) encountered on decaying substrates, like fungi, carrion, dung and rotting vegetation, preferably in woodland habitats. No species of Acartophthalmidae was formerly recorded from the Gemer area but two species have been found during recent surveys.

Acartophthalmus bicolor Oldenberg, 1910 Material: Muránska planina NP, Tisovec 3 km W, Furmanec valley, 48°41'23''N, 19°53'57''E, 490 m, on rotting tree trunks, 12.vii.2011, 1♂, J. Rohá ček leg. (SMOC). Remarks: A Holarctic species, less common than A. nigrinus . Adults occur on carrion, rarely on decaying fungi. The specimen recorded above was probably associated with a rotting tree .

Acartophthalmus nigrinus (Zetterstedt, 1847) (Fig. 1) Material: Muránska planina NP, Fabova ho ľa res., MT, 15.v.-16.vi.2009, 3 ♂3♀, 16.vi.-25.viii.2009, 3 ♂1♀, all J. Šev čík leg.; Muránska Huta-Šiance res., sweeping undergrowth of beech forest, 7.x.2010, 1 ♀; Muránska planina NP, Šiance res., top plateau, 48°46'11''N, 20°04'14''E, 1000 m, on excrement, 7.ix.2011, 4♂2♀, J. Rohá ček leg. (SMOC). Remarks: A widespread Holarctic species, the most common representative of the family. It is associated with woodland habitats where adults occur on decayed fungi and carrion.

ANTHOMYZIDAE

A small acalyptrate family (cca 100 species worldwide) having 32 species in Europe and adjacent island areas and 18 in Slovakia (Rohá ček 2006, 2009a,d). Adults are slender flies with short legs living in various humid habitats like damp meadows, swamps (Fig. 7), bogs and waterlogged forests with rich undergrowth. Larvae of the majority of species are phytosaprophagous and feed between the leaf sheaths of the tillers of graminoid plants (Poaceae, Cyperaceae, Juncaceae, Typhaceae), most often in those damaged by phytophagous or other enemies. A few species are associated with dicotyledonous plants; only species of the genus Fungomyza develop in the sporocarps of fungi. Hitherto only 9 species are known in the Gemer area (4 recorded by Rohá ček 1983, 1986a; 5 added here) but up to 5- 7 more species can be expected here.

OPOMYZIDAE

This small family (about 60 species worldwide) includes 33 species in Europe and adjacent areas as delimited in Fauna Europaea (van Zuijlen 2007; van Zuijlen & Rohá ček 2006); 17 of them have been recorded from Slovakia (Rohá ček 2009e). Opomyzidae are normally associated with grassland habitats (including cereal fields) but some species can also inhabit the grassy undergrowth of forests. The larvae are phytophagous, developing in stems of graminoid herbs and causing “dead heart” damage to grasses; several species are cereal pests. Only 8 species are known from the Gemer area, 6 being recorded already by Martinek

(1976, 1984, 1985, 1986) and Martinek & Mocek (1995) but some under incorrect species names, see van Zuijlen & Rohá ček (2006).

*Geomyza apicalis (Meigen, 1830) (Fig. 2) Literature: Murá ň (Martinek 1976, 1986), Tur ňa nad Bodvou (Martinek 1985, 1986, both as G. hendeli Czerny, 1928; corrected by van Zuijlen & Rohá ček 2006). Remarks: A Holarctic species; known only from North and Central Europe in the Palaearctic Region and from Canada in the Nearctic Region. The species was considered critically endangered (CR) in the Czech Republic (Martinek & Barták 2005) but this is probably not the case (cf. van Zuijlen & Roháček 2006) despite that it is sporadically collected both in the latter country and Slovakia.

Rohá ček leg. (SMOC, 2 ♂2♀ in coll. J. W. A. van Zuijlen, Waalwijk, The Netherlands). Remarks: A poorly known species, hitherto only recorded from North and Central Europe and from Bulgaria. It seems to be associated with montane grasslands in Central Europe. It has been only recently recorded from Slovakia, viz., from Oravský Podzámok (Papp 2007) and several localities in the Po ľana Mts (van Zuijlen & Rohá ček 2009). Its common occurrence in the grass Brachypodium pinnatum is noteworthy.

Rohá ček leg. (SMOC). Remarks: A Holarctic species; widespread in Europe and introduced in Canada (Wheeler et al. 1999). Common in meadows but it may sometimes also attack cereals.

STENOMICRIDAE

A species-poor family with only four genera worldwide (Papp 2006) and two genera and three species in Europe (Merz & Rohá ček 2005); only one species is known from Slovakia (Rohá ček 2009f). The family was erected for species by Papp (1984), but previously and often subsequently this group has been treated as a member of the or the Periscelididae, most recently as a subfamily of the latter. Adults are very minute delicate flies with yellow to grey body. Biology of Stenomicridae is largely unknown. The larvae probably develop in the water-holding leaf bases of plants, particularly monocotyledons. The adults of two European species were found (and even reared) from tussocks of large Carex and Scirpus species (see Rohá ček 2009i) but Podocera soniae may be associated with dicotyledonous umbellifers (see Merz & Rohá ček 2005). This only Slovak representative of the family was already recorded from the Slovenský kras by Rohá ček (1983) under the name Stenomicra delicata .

106

*Podocera soniae (Merz & Rohá ček, 2005) Literature: Slovenský kras-Zádiel (Rohá ček 1983, 1986c, misidentified as Stenomicra delicata ; Merz & Rohá ček 2005, 2 ♀ paratypes, as Stenomicra (Podocera) soniae ). Remarks: A little known species, hitherto only recorded from Bulgaria, Czech Republic, Germany, Romania, Slovakia and Switzerland (Merz & Rohá ček 2005). It was partly described from specimens (paratypes) collected by me at light in Zádiel on 15. and 16.vi.1981. Besides this finding the species was recorded from only one other locality in Slovakia (Bártfa /= Bardejov/, see Merz & Rohá ček 2005). Adults can be collected in open or semiopen habitats but usually only by means of Malaise or pan traps. The species is considered vulnerable (VU) in the Czech Republic (see Rohá ček 2005b).

PERISCELIDIDAE

Another small family (excluding the Stenomicridae, often considered a subfamily of Periscelididae), having about 50 species worldwide and 5 species (plus 1 subspecies) of the genus Loew, 1858 (including the subgenus Myodris Lioy, 1864 sometimes treated as a genus) in Europe (Papp & Withers 2011) three of which are also known from Slovakia (Máca 2009). Adults of Periscelis species are small to minute flies with yellow and brown variegated legs and thorax and a pectinate arista. They are infrequently collected because of occurring on and around wounded deciduous trees usually at the height of the tree canopy and feed, like its larvae, on fresh exuding sap on the surface of bark. Only one species was recorded from the Gemer area (Máca 1986; Rohá ček 1987), then as a first representative of the family in Slovakia.

Periscelis (Myodris) annulata (Fallén, 1813) Literature: Slovenský kras-Zádiel (Máca 1986; Rohá ček 1987). Remarks: A widespread European species, also reported from the Nearctic Region. Although it is the most frequently recorded member of the family in Europe there are only two previous records from Slovakia, viz. the above from the Slovenský kras and that by Rohá ček (1995b) from the Bukovské vrchy Mts (Ruský Potok).

ASTEIIDAE

This opomyzoid family is represented by only 19 species and 4 genera in Europe and adjacent archipelagos (Carles-Tolrá 2007; Gibbs & Papp 2007). A total of 8 species are known to occur in Slovakia (Rohá ček 2009g). They belong to two genera representing also ecologically different groups. The Leiomyza species are mycophagous as larvae and develop in sporocarps of macrofungi in forested habitats, while species of Asteia have larvae obviously (phyto)saprophagous and adults occurring in open or semi-open habitats, often on flowers. Five species were previously recorded from the Gemer area (Rohá ček 1985, 1986b) based on material collected by me in 1980-1984.

Asteia amoena Meigen, 1830 Literature: Jelšavská Teplica, Slavec, Slovenský kras-Drienovec (Rohá ček 1986b).

107

Remarks: A Palaearctic species, mainly associated with more humid grassland habitats, most often in tall graminoid vegetation.

*Leiomyza curvinervis (Zetterstedt, 1838) Literature: Murá ň-Hrdzavá dolina (Rohá ček 1985, 1986b). Remarks: Although widespread in the Holarctic Region this species is uncommon and restricted to montane forests in Central Europe; it is considered vulnerable (VU) in the Czech Republic (Rohá ček 2005c). There are only a few records in Slovakia: Vysoké Tatry Mts, Po ľana Mts ( Ľubietovský Vepor) and the above locality from Murá ň Mts (see Rohá ček 2009h).

Leiomyza dudai Sabrosky, 1956 Literature: Murá ň (Rohá ček 1986b). Material: Slovenský kras, Drienovec res., sweeping, 5.ix.2008, 2 ♂, J. Šev čík leg. (SMOC). Remarks: An Eurasian, mycetophagous species, common on fungi in woodland but also (less frequently) open habitats (pastures).

Leiomyza scatophagina (Fallén, 1823) Literature: Murá ň-Hrdzavá dolina, Slovenský kras-Zádiel (Rohá ček 1986b). Remarks: A Holarctic species, but in the Palaearctic Region only known from North and Central Europe. It is uncommon on decayed fungi in various types of forest.

Discussion and conclusions

Despite the fauna of the opomyzoid families treated here not being known satisfactorily (particularly when compared with that of the Po ľana Biosphere Reserve, see in Rohá ček & Šev čík 2009) the present, although somewhat fragmentary, knowledge indicate that the Gemer area hosts interesting communities including species important from the faunistic, ecological, biogeographical or nature conservation point of view. Podocera soniae (Stenomicridae) was partly described from specimens originating from this territory, having there one of the two known localities in Slovakia, similarly as has Periscelis annulata (Periscelididae); neither of these species has been recorded from the Po ľana Biosphere Reserve. There are also several saproxylic and mycophagous species in the area characteristic of old montane or submontane forests (Fig. 6), viz. Clusia tigrina (Fig. 5), Clusiodes caledonicus , Hendelia beckeri (Clusiidae) and Leiomyza curvinervis (Asteiidae) all of which are under jeopardy in terms of nature conservation. On the contrary, Geomyza apicalis (see Fig. 2) and G. hackmani (Opomyzidae), another vulnerable species, are typical members of grassland communities. Although the marshland habitats are (particularly in lowland) generally scarce in the Gemer region, several species characteristic to them have been found, including two uncommon and vulnerable species, viz. Anthomyza neglecta and A. para- neglecta (Anthomyzidae, Fig. 4)

It is certain that further specially aimed fieldwork could reveal additional species of these and related families (e.g. Aulacigastridae) in the Gemer area, possibly also those formerly unrecorded from Slovakia. In this context additional biodiversity research is desirable in this interesting territory.

Acknowledgements: I should like thank J. Šev čík (Ostrava, Czech Republic), J. Máca ( České Bud ějovice, Czech Republic) and Ľ. Vidli čka (Bratislava, Slovakia) who enabled me to study the material they collected in the Gemer area, partly within the framework of the ATBI project (see www.atbi.eu). The kind assistance of J. Šev čík, D. Kasp řák (Ostrava, Czech Republic) and J. Tesák (Administration of the Muránska planina National Park, Revúca, Slovakia) in field work in the Muránka planina NP in 2011-2012 is also much appreciated. I am very grateful to P. Chandler (Melksham, U. K.) for kind language revision of the article and useful comments and to J. W. A. van Zuijlen (Waalwijk, The Netherlands) for the identification of the Geomyza species. The study was supported by grant of the Silesian Museum no. IGS201103 and also by grant no. P506/10/1666 of the Czech Science Foundation.

Fauna opomyzoidních čeledí Clusiidae, Acartophthalmidae, Anthomyzidae, Opomyzidae, Stenomicridae, Periscelididae a Asteiidae (Diptera) v Gemerské oblasti (st řední Slovensko)

Je podán p řehled dvouk řídlých sedmi čeledí nad čeledi Opomyzoidea (Diptera) v Gemerské oblasti (Slovensko), která zahrnuje Národní parky Muránska planina, Slovenský raj a Slovenský kras. Na základ ě publikovaných údaj ů a studovaného materiálu je z této oblasti uvedeno 8 druh ů čeledi Clusiidae, 2 druhy čeledi Acartophthalmidae, 9 druh ů čeledi Anthomyzidae, 8 druh ů čeledi Opomyzidae, po 1 druhu z čeledí Stenomicridae a Periscelididae a 5 druh ů čeledi Asteiidae. Každý z těchto druh ů je pojednán s informacemi o jeho celkovém rozší ření, faunistice na Slovensku, bionomii a významu pro ochranu p řírody. Nejzajímav ějším druhem je Podocera soniae (Merz & Rohá ček, 2005) (Stenomicridae) nebo ť jde o taxon částe čně popsaný podle exemplá řů (paratypy) objevených v této oblasti. Dalšími významnými faunistickými prvky jsou Clusia tigrina (Fallén, 1820), Clusiodes caledonicus (Collin, 1912), Hendelia beckeri Czerny, 1903 (Clusiidae) a Leiomyza curvinervis (Zetterstedt, 1838) (Asteiidae), vše ohrožené nebo zranitelné druhy vázané na zachovalé lesní porosty, nebo Anthomyza neglecta Collin, 1944, A. paraneglecta Elberg, 1968 (Anthomyzidae), Geomyza apicalis (Meigen, 1830) a G. hackmani Nartshuk, 1984, zranitelné druhy mok řadních a travnatých ekosystém ů.
