Meinertellidae
Family of jumping bristletails
From Wikipedia, the free encyclopedia
The Meinertellidae, commonly known as rock bristletails, is a small family of basally diverging insects belonging to the order Archaeognatha. These insects can be distinguished from members of the other Archaeognatha family, Machilidae, by the lack of scales at the base of the legs and antennae, head, and palps; along with possession of small abdominal sternites protruding slightly between the coxal plates. They can also be distinguished by patches of reddish to violet-brown hypodermal pigment on the appendages.[1]

Machilontus group:[1]
| |
Members of Archaeognatha are generally petrophilous ("rock-loving"), but species of Meinertellidae living in the Amazon have adapted to a life among the leaf litter on the forest floor, on the tree trunks and up in the canopy. In this wet environment, their eggs have a tolerance for being submerged in water.[2]
Meinertellidae comprise more than 170 species in 19 genera, grouped into the Machiloides group, Machilinus group, Hypomachiloides group, Machilontus group, and Meinertellus group.[1]
Distribution
These insects are principally found in the southern hemisphere, and can be found in rain forests, regular forests, and on coastal cliffs.
