Meanings
- not comparablerarebiologyOf certain diplurans, having an abnormally high number of thoracic spiracles (openings for respiration).
A hyperpneustic condition occurs in the dipluran family Japygidae, where additional spiracles are present in the meso- and metathorax.
2013, Beutel, Rolf, Insect morphology and phylogeny : a textbook for students of entomology, page 851 more example
In the most primitive condition twelve spiracles are present, being located on each of the thoracic and the anterior nine abdominal segments. This condition, however, is only known in the embryonic state of Leptinotarsa, In the postembryonic stages eleven pairs of spiracles, at most, are exceptionally present in the hyperpneustic insects, such as Japyx spp., which are provided with the prothoracic spiracles.
