Mormidea notulifera Stål, 1860: 21 .

Mormidea (Mormidea) notulifera: Berg, 1878: 300 ; Kirkaldy, 1909: 60; Pennington, 1920: 7; Pirán, 1948: 12; Rolston 1978: 191.

Material studied. Derrubadas: 1♂, Parque Estadual do Turvo, Estrada Salto 13.IV.1983, S. L. Bonatto leg., S. L. Bonatto det. 1985 ( UFRG) . Júlio de Castilhos : 1♀, 19.X.1981, Link & Costa leg., Tremoço, J. Grazia det, 1986 ( UFRG) ; 1♂, 19.XI.1981, Link & Costa leg., Tremoço. Santa Maria: 1♂, 15.XI.1973, J. A. Fonseca leg., J. Grazia det. 1986 ( UFRG) ; 1♂, 28.IV.1981, D. Link leg. ( UFRG) .

Diagnostic features. Body dorsal surface light castaneous, humeral angles black, pale yellow spots next to cicatrices of pronotum ( Fig. 85 ); ventral surface yellow. Anterolateral margins of pronotum concave. Humeral angles slightly produced and obtuse. All angles of scutellum and apex of radial vein of corium with a pale yellow callosity each ( Fig. 85 ). Body length: 7.00– 8.50 mm ( Garbelotto & Campos 2014).

Recorded host plants. Oat ( Campos et al. 2009), rice ( Link & Grazia 1987; Weber et al. 1988; Campos et al. 2009) and wheat ( Link & Grazia 1987; Campos et al. 2009).

Distribution in Rio Grande do Sul. Derrubadas, Guaíba, Júlio de Castilhos, Santa Maria and São Francisco de Paula ( Fig. 87 ).

Comments. The damage this species causes in rice depends on the development stage of the plant. During the milk stage of grain filling, rice grains wither due to the stink bug’s feeding. During dough phase the punctured area darkens and thickens.
