Insects can be divided into two groups historically treated as subclasses: wingless insects, known as Apterygota, and winged insects, known as <answer>Pterygota</answer>. The Apterygota consist of the primitively wingless order of the silverfish (Thysanura). Archaeognatha make up the Monocondylia based on the shape of their mandibles, while Thysanura and <answer>Pterygota</answer> are grouped together as Dicondylia. The Thysanura themselves possibly are not monophyletic, with the family Lepidotrichidae being a sister group to the Dicondylia (<answer>Pterygota</answer> and the remaining Thysanura).
