There are two forms of Scaphidium quadriguttatum: one in which the elytra have two pairs of orange, peanut-shaped marks on the elytra, and a second which is unmarked, essentially all black. This latter form is treated as S. piceum by some authors. However S. piceum is a “nomen nudum”, as there is no literature published to date yet which raises this form to full species.
