New records of these species and confirmation of M. ornata at locality Šaprance suggest huge potential and invite further faunistic research in southeastern Serbia.

Nove najdbe teh vrst in potrditev vrste M. ornata na najdišču Šaprance kažejo na velik potencial in vabijo k nadaljnim favnističnim raziskavam v jugovzhodni Srbiji. KLju ČNe Be Se De : Lepidoptera, Hesperiidae, Nymphalidae, favna, Srbija At locality izvor, on r udina planina Mt. in southeastern Serbia (42.513227 N 22.519799 e , 954 m.a.s.l.), we recorded two rare butterfly species – Melitaea ornata Christoph, 1893 and Muschampia cribrellum (e versmann, 1841). Spinose skipper (Muschampia cribrellum) is a rare and local species from family Hesperiidae. its range includes large part of Asia and only small part of e urope, and its presence was confirmed from r omania, Bulgaria, North Macedonia and Serbia. (Tolman & Lewington 2008; Dincă et al. 2010; Haahtela et al. 2011). in Bulgaria 159 ACTA ENTOMOLOGICA SLOVENICA LJUBLJANA, DECEMBER 2020 Vol. 28, øt. 2: 159–164 and North Macedonia, this species was registered at several dry steppe-like localities, similar to that in Serbia (Dincă et al. 2010). The species was found in Serbia only re- cently, and thus far was recorded only from few localities in Stara Planina Mt. (Popović et al. 2013). New record from izvor village at r udina Planina Mt. is also the southernmost point of its distribution in Serbia. Acta entomologica slovenica, 28 (2), 2020 160 Figure 1.

Djurić). e astern Knapweed Fritillary (Melitaea ornata) is a rare and local species of butterfly from family Nymphalidae whose distribution in e urope is not well understood due to confusion with similar species Melitaea phoebe (Denis & Schiffermüller, 1775), but also because certain authors ignore its presence in e urope (r ussell & Ten- nent 2016). The most reliable method for identification of this species is observation of caterpillars, since they have red head, unlike congenial species M. phoebe whose caterpillars have black head. The other possibility is to perform DNA analysis. r ussel et al. (2014) also described a potential hybridization of these species. Although the range of M. ornata isn’t well known, this species is registered in many e uropean countries, including Balkan Peninsula. This species was registered both in Bulgaria and North Macedonia, which are closest records to the localities in Serbia (r ussel & Pateman 2019).

Vujić M. (Figure 2 C-D). Notes New records extended the known distribution of both mentioned species. For M. cribrellum this is the southernmost record in Serbia that substantially extends its known distribution towards south and connects localities at Stara Planina and North Macedonia. For M. ornata this is the easternmost record in Serbia, although this species is probably much more widespread in Bulgaria and Serbia (Figure 3 A). in both cases for Serbia these are earliest records in the season. Conclusion in just a few field days spent in southeast Serbia a lot of rare butterflies and other insects were recorded. Among them special attention deserve rare and extremely Acta entomologica slovenica, 28 (2), 2020 162 Figure 3.

New records of these species and confirmation of M. ornata at locality Šaprance undoubtedly suggest huge potential and invite further insect research in southeast Serbia. Among visited localities special attention deserves izvor village at r udina Planina Mt. (Figure 3 B), due to existence of inter- esting habitats where many rare species were registered, inter alia M. ornata and M. cribrellum.
