5.2.14. The Scaphisoma pictum species group

Members of the group share with the Palaearctic S. assimile Erichson, 1845 and its allied species a bilobed apical process of the median lobe, but usually differ drastically by the broadly lobed parameres. The elytra, unlike those in members of the S. assimile group, lack basal striae (LÖBL 1971b: 962). Scaphisoma cuyunon, S. hexameroides and S. iridescens which have basally broadened but not lobed parameres are tentatively placed in this group.
