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).

Distribution in Turkey. İstanbul (this work).
