== Characteristics == === Size === The Heteropterygidae include both very small and very large and massive species. The representatives of the Dataminae are consistently rather small. So Planispectrum species are only long. The largest Dataminae species, with a maximum length of , are within the genera Pylaemenes and Orestes.
