. Diagnosis. 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 View FIGURE4 ); last pregenital segment of abdomen ventrally expanded, with tumid setose process covering base of genital segment on left side; ( Fig. 7 View FIGURE 7 ) apical process of left paramere comparatively thick and short, with posteriorly notched dorsal crest and very long setae on sensory lobe ( Fig. 11 View FIGURE 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).
