Melanacanthus margineguttatus; the brown bean bug (or small brown bean bug), Melanacanthus scutellaris, is similar. It also attacks pulses. (Note, there is little information on Melanacanthus margineguttatus in the literature, mostly reports are on Melanacanthus scutellaris - a species native to Australia.)
