This species belongs to a group of yellow-flowered species with the leaves abaxially densely sericeous
, mostly limited to eastern and southern Brazil (ser.
This large Holarctic genus is primarily diagnosed by the following characters: body variable in coloration, not exhibiting green tinge, oval to elongate oval, with length 3-6 mm, sometimes shortened and broadened in 9; dorsal surface with simple setae and woolly or sericeous
, scalelike setae that are very easily abraded; pronotum, scutellum and hemelytra weakly shagreened, usually with densely distributed, scalelike setae and simple, darker setae; metafemur rather tumid; male genital segment usually with a longitudinal, mesal keel ventrally; endosoma generally C-shaped, not strongly twisted, with rather complex apical region.
