| 1. | It is an important diagnostic character in most handbooks for identifying mushrooms.
|
| 2. | The colour of the flowers is not a diagnostic character.
|
| 3. | Cheek and Jebb identified seven diagnostic characters that they used to define the group:
|
| 4. | The species is hermaphrodite; the genitalia are a key diagnostic character at the species level.
|
| 5. | Most diagnostic character of its suture is its weakly developed adventitious lobe in the first lateral saddle.
|
| 6. | Its sinuous appearance, with several branches and notches, makes it a diagnostic character for this species.
|
| 7. | The length of the tail is not a reliable diagnostic character for this species, as it is frequently damaged.
|
| 8. | The most important diagnostic characters in comparison to other species are oval scolex and suckers, with relatively elongated neck.
|
| 9. | The size and shape of the staminodes and of the structures at the base of the filaments are important diagnostic characters.
|
| 10. | Additional diagnostic characters were proposed by the authors, but their character-states cannot be determined in other protosuchian taxa.
