Martovce, Žitava River [alluvia], 47°51′38″N, 18°08′25″E, 106 m a.s.l., 26.ix.2014 , 1 ♀ (apterous), lgt. & det. P. Kment (coll. National Museum, Prague, Czech Republic ). Remarks. The species was found in heavily vegetated river alluvia in species-rich assemblages of aquatic invertebrates including the following water bugs: Nepa cinerea , Hesperocorixa linnaei , Sigara striata , Cymatia coleoptrata , Ilyocoris cimicoides , Notonecta glauca , Plea minutissima , Hydrometra gracilenta , Microvelia reticulata and Gerris argentatus . Distribution. This Holarctic species is distributed from the United Kingdom to northern China , Canada and northern United States . The southern boundary in Europe is delineated by France , Germany , Austria , Hungary , Romania and Ukraine ; it is absent in southern Europe ( Putshkov & Putshkov 1996 , Rabitsch & Zettel 2000 , Aukema et al. 2013 , Kment et al. 2013 , Berchi & Kment 2015 ). The species prefers shaded littoral zones of ditches, marshes and ponds, where it is particularly abundant among emergent macrophytes and submerged branches of shore vegetation ( Wróblewski 1980 , Aukema et al. 2002 ). Kurzatkowska (1999) considered M. buenoi a tyrphophilous species, inhabiting various dystrophic, polyhumic waters, especially in forests.
