Peninsula (Araneae,Salticidae)

Abstract:ThetaxonomicpositionofthepoorlyknownspeciesRoeweriellabalcanicaKratochvil,1932fromCroatia
isdiscussed.Thespecies is illustrated and re-described onthe basisofthe 9 holotype.ThegenusRoeweriella
Kratochvil, 1932 (type species:/?,balcanica Kratochvil, 1932 by monotypy) is synonymized with Marpissa C.L.
Koch, 1846,and therefore the new combination,Marpissa (Marpissa) balcanica (Kratochvil, 1932) comb.nov., is
proposed.
