Isoneuromyia czernyi ( Strobl, 1909)

( Figs 5–10 , 18–19 )

Material examined. SLOVAKIA: Muránska planina National park, Havraní dolina Nature Reserve, 13.vii.2015, 2 ♂♂ 1 ♀, M.Tkoč, J. Roháček & J. Ševčík leg., J. Ševčík det. ( JSL-UOC).Muránska planina National park, Šarkanica Nature Reserve, 9.viii.–5.ix.2017, 1 ♂, M.Tkoč, J. Roháček & J. Ševčík leg., J. Ševčík det.( JSL-UOC).Slovenský kras National park,Drieňovec National Nature Reserve, 5.ix.2008, 1 ♂, J.Ševčík leg.,det.et coll.(misidentified as Isoneuromyia semirufa , see ŠEVČÍK & KURINA 2011).

Comments. A rare species, hitherto known only from the Mediterranean region. It was described as a single male from Spain ( STROBL 1909), without providing any illustration, and subsequently a female was recorded from Greece by CHANDLER et al. (2006). This is the first record from Slovakia, as well as from central Europe.The figures of male terminalia, habitus and wings are published here for the first time ( Figs 5–10 ). The DNA sequence of the barcode region (COI) is also provided ( Table 3). This species was observed visiting the inflorescence of Chaerophyllum aromaticum ( Apiaceae , Figs 18–19 ), presumably feeding on nectar, indicating that Isoneuromyia species can potentially be considered as pollinators, although transfer of pollen from one flower to another has not been observed.

Isoneuromyia pseudochracea ( Landrock, 1925)

( Figs 11–17 )

Material examined. SLOVAKIA: Muránska planina National park: Kučalach, 15.vii.2014, 1 ♂ ; Tisovec , Furmanec brook, 12. vii. 2011, 2 ♂♂, all J. Ševčík leg. & det. ( JSL-UOC) .

Comments. This name was introduced by LANDROCK (1925) as a replacement name for the preoccupied name Platyura ochracea Dziedzicki, 1925 . This species is known from several sparse records in western and central Europe ( EVENHUIS 2006). This is the first record from Slovakia. A figure of the male terminalia ( Figs 14–16 ), as well as DNA sequence of the barcode region (COI), are provided ( Table 3).
