( Figs 56–58View FIGURES 56–58)

Cimex heros Fabricius, 1798: 532  .

Euschistus apicalis Dallas, 1851: 203  .

Euschistus heros: Stål, 1868: 26  ; Rolston, 1974: 46–49; Bianchi et al. 2019.

Material studied. Cruz Alta : 2♂, 2♀, 24.V.2006, M. T. B. da Silva leg. ( UFRG)  . Derrubadas : 1♀, 13.IV.1983, S. L. Bonatto leg. ( UFRG)  ; 2♂, 1♀, 26–30.IX.1983, S. L. Bonatto leg. ( UFRG)  . Santa Maria : 1♂, 1♀, X. 1980, D. Link leg. ( UFRG)  .

Diagnostic features. Body dorsal and ventral surfaces castaneous. Mandibular plates subequal to clypeus, rounded apically ( Fig. 57View FIGURES 56–58). Internal angles of cicatrices of pronotum dark castaneous. Anterolateral margins of pronotum concave and serrate ( Fig. 57View FIGURES 56–58). Humeral angles dark, strongly developed, rounded apically and directed anterolaterally ( Fig. 57View FIGURES 56–58). Scutellum with pale spots and apex with large pale callosity ( Fig. 56View FIGURES 56–58). Connexivum dark castaneous with a pale macule, posterior angle produced. Posterior margin of abdominal sternite 7 acute. Body length: 10.00–11.00 mm.

Recorded host plants. Canola (Marsaro Jr. et al. 2017; Bianchi et al. 2019), maize ( Roza-Gomes et al. 2011) and soybean ( Link & Grazia 1987; Medeiros & Megier 2009; Chevarria et al. 2013; Scopel et al. 2016). Also reported feeding in mature seeds of red-root amaranth ( Amaranthus retroflexus  ), and mature fruits of S olanum megalochiton  , S. mauritianum  and Vassobia breviflora ( Medeiros & Megier 2009)  .

Distribution in Rio Grande do Sul. Augusto Pestana, Cruz Alta, Derrubadas, Passo Fundo, Santa Maria, Santa Rosa, and Três de Maio ( Fig. 58View FIGURES 56–58).

New records. Cruz Alta and Derrubadas.

Comments. This species is known as the brown bug or soybean bug. The damage results from the suction of sap from the branches or stems and from pods, limiting production. They also inject toxins, causing “leaf retention”.
