Ruspolia nitidula (SCOPOLI 1786)

Distribution in Slovakia

Before 1962, this species had been found in Slovakia only at 19 localities (reviewed by KRIŠTÍN & SÁROSSY 2004). Subsequently until 2000, there were no published data on its occurrence, apart from an occurrence in August 1982 in the Danube area ( CHLÁDEK & GAVLAS 2004). In 2000-2006, suitable localities were mapped more intensively, and we found this species on 87 localities (we confirmed pre-1962 findings in ten localities). Summarizing all known published and our unpublished data, the species was found in total at 100 localities in 67 squares of the Slovak Fauna Databank (16 % of all squares; Fig. 1 , Appendix 1). Possibly it was more intensive research that has detected this elusive species in greater number of localities; this apparent increase is not an indication of northward spreading ( KRIŠTÍN et al. 2007). This evidence can be regarded as debatable, but finally, it supports improved species detection ( BRAUN et al. 1995, BERG & ZUNA- KRATKY 1997).
