Comment. Temnostethus gracilis is a widespread species known from most of Europe, including the Balkans. It is a predacious species known to feed on Sternorrhyncha species. It was observed to live on numerous deciduous tree species such as Malus, Pyrus, Prunus, Crataegus (Rosaceae), Fraxinus (Oleaceae), Quercus, Fagus (Fagaceae), Betula, Corylus (Betulaceae), Acer (Sapindaceae), Salix, Populus (Salicaceae) (PÉRICART 1972). Temnostethus gracilis differs from T. winkelmanni WAGNER, 1961 and T. longirostris (Horváth, 1907) in shorter clypeus and the existence of brachypterous form, from T. pusillus (Herrich-Schäffer, 1835) by pale second antennal segment, and from T. tibialis Reuter, 1888 by much shorter and sparser setae on hemelytra which are almost invisible (Fig. 5G) (PÉRICART 1972).
