How many species of Diplura are there?
800 species
dipluran, (order Diplura), also called two-pronged bristletail, any of a group of about 800 species of small primitive wingless insects, considered by some entomologists to have features similar to ancestral insects.
Where are Diplura found?
Diplurans live in the soil and are found in moist habitats under rocks, logs, leaf litter, and tree bark. Some species live in caves.
Are earwigs Diplura?
Diplurans (Order Diplura) can be distinguished from earwigs by a lack of eyes, paired ventral appendages under all or most of the abdominal segments and tarsi (toes) with only one segment.
What are insect cerci?
Cerci (singular Cercus) are paired appendages on the abdomen of many species of insect. Cerci perform a sensory function. The size of cerci varies between species with some having barely discernible cerci while others, like earwigs, having stout and obvious cerci (sometimes called pincers).
How many legs do Diplura have?
three pairs
Characteristics. Diplurans resemble symphylans (class Symphyla), or perhaps silverfish (order Thysanura), bristletails (order Archeognatha), or proturans (order Protura). However, they have only three pairs of legs, so they are easily distinguished from the many-legged Symphyla.
How many species of Thysanura are there?
370 species
There are around 370 species from four different families in the order Thysanura. Their distribution is worldwide.

What is a Diplura?
The order Diplura is one of the four groups of hexapods, alongside insects, Collembola (springtails) and Protura. They are sometimes called “two-pronged bristletails”. Around 800 species have been described, of which around 70 occur in North America, 12 in Great Britain and two in Australia.
What is another word for diplurans?
… (Show more) dipluran, (order Diplura), also called two-pronged bristletail, any of a group of about 800 species of small primitive wingless insects, considered by some entomologists to have features similar to ancestral insects.
Is the Diplura a monophyletic Entognatha?
The relationships among the four groups of hexapods are not resolved, but most recent studies argue against a monophyletic Entognatha. The fossil record of the Diplura is sparse, but one apparent dipluran dates from the Carboniferous.
What are the characteristics of diplurans?
Diplurans have long antennae with 10 or more bead -like segments projecting forward from the head. The abdomens of diplurans bear eversible vesicles, which seem to absorb moisture from the environment and help with the animal’s water balance.
