Which order contains the extinct family Dasyleptidae and the extant families Meinertellidae and Machilidae?

• A. Blattaria
• B. Mantodea
• C. Phasmatodea
• D. Archaeognatha

Answer: (D)

The answer rests on recognizing an ancient, primitive group of wingless insects: Archaeognatha, the jumping bristletails. This order includes the two living families Meinertellidae and Machilidae, as well as the extinct family Dasyleptidae, showing that all three belong to the same lineage. The other options are different insect orders and do not contain these families. Blattaria refers to cockroaches, Mantodea to mantises, and Phasmatodea to stick insects. So the order that unites Dasyleptidae, Meinertellidae, and Machilidae is Archaeognatha.
