Phylogenetic relationships among major lineages of Ommatidae. Red lines are the known extinct taxa, blue lines are extant taxa. Different color dots show different sites with fossils. Significant characters in Ommatidae phylogeny: 1. Pentagonal enlarged window punctures along elytral suture; 2. Third antennomere distinctly elongated; 3. Regular row of large window punctures present along external elytral margin; 4. Abdominal ventrites flattened; 5. Gular sutures incomplete or absent; 6. Epipleural rim with more than one row of cells; 7. Median epicranial suture on the dorsal head surface; 8. Head with ventrolateral antennal grooves.
