Remarks. In Romania, this species was identified at seven sites at an elevational range of 203–2090 m a.s.l. ( Fig. 1 ). It was found from May to September, in streams, lakes and ponds. All specimens examined were macropterous. Limnoporus rufoscutellatus is considered monomorphic (long-winged) and univoltine ( Vepsäläinen 1974b, Vepsäläinen & Nieser 1977, Andersen & Spence 1992).

Distribution. Widespread in the Palaearctic Region, but absent in the Iberian Peninsula, northern Africa and the Middle East. In the Nearctic Region, it is known from Alaska and northwestern Canada ( Andersen 1995, Kanyukova 2006, Damgaard et al. 2014). For the Romanian distribution, see Fig. 2 .
