Definition of Diplura in English: Dipluraplural noundɪˈplʊərədīˈplo͝orə Entomology An order of small primitive wingless insects which resemble the true bristletails but have two bristles at the end of the abdomen. Order Diplura, subclass Apterygota, class Insecta (or Hexapoda) Example sentencesExamples - Neither are the Parainsecta (springtails and proturans) or Diplura true insects, for their numbers of abdominal segments vary.
- Similar functions have been proposed for eversible vesicles in other terrestrial arthropods including Diplura and Machilidae.
- There are huge gaps in the early fossil record, since several basal hexapod groups have not been found at all in the Paleozoic: Protura, Diplura, and Thysanura.
- When nucleotide frequencies were tested within each of the three basal hexapod groups (i.e., within Protura, within Diplura, within Collembola), they were always stationary.
- The Parainsecta (springtails and proturans) and Diplura are not true insects, for their numbers of abdominal segments vary.
Derivatives adjective & noun Entomology The study yielded new cave records for amphipods, isopods, diplurans, and carabid beetles. Example sentencesExamples - Some dipluran species are herbivorous and feed on plants and plant material.
- Similar to some other primitive wingless insects, diplurans have external sexual reproduction.
- The cerci of some diplurans are designed to break off near the base if they are mishandled.
- We have obtained the most extensive sample of basal hexapods so far: namely, 10 proturans, 12 diplurans, and 10 collembolans, including all their major subgroups - plus a wide range of out-group taxa.
