Recognized by the following combination of characters: total length male 3.8–4.9, female 4.4–5.0; both sexes always macropterous; antennal segment I reddish to dark brown; segment II less than 1.4 X as wide as basal width of pronotum ( Fig. 4 ); last pregenital segment of abdomen ventrally expanded, with tumid setose process covering base of genital segment on left side; ( Fig. 7 ) apical process of left paramere comparatively thick and short, with posteriorly notched dorsal crest and very long setae on sensory lobe ( Fig. 11 ). Most similar to D. errans in the coloration of dorsum, size, and body proportions but the latter species differs from D. cerastii in the symmetric, non-modified abdominal segment VIII, left paramere with relatively short setae on the sensory lobe, distinctly curved apex and gradually diminishing, not notched dorsal crest, and longer antennal segment II. Distribution . This species is known from several countries in southern Europe, spanning west to Izmir , western Turkey , and Crimea ( Wagner 1974 ). Host . Dicyphus cerastii was reported from several host plants including Cerastium arvense L. ( Caryophyllaceae ) ( Wagner &Weber 1964 ; Wagner 1974 ), Salvia glutinosa L.( Lamiaceae ), Digitalis grandiflora Mill.(Scrophulariaceae) ( Ingegno et al . 2008 ), and Solanum lycopersicum L. ( Solanaceae ) ( Sanchez & Cassis 2018 ).
