Felsenspringer

As Machilidae one of two families of rockhopper ( Archaeognatha ) is called. It is in contrast to the family of Meinertellidae which must be designated as second and much smaller rocks Springer family, rather rich in species. It can be distinguished within the Machilidae 26 genera with about 250 species. Machilidae and Meinertellidae ( = Archaeognatha ) represent primeval insects belonging to the Ectognatha ( = Freikiefler ), which can be characterized among other things by the exposed mouthparts on the head capsule. The Ectognatha heard the majority of insects. The sister group of the Ectognatha are the Entognatha, which for example the Diplura ( = double tails) or springtails ( Collembola = ) are attributable.

Reproduction

The reproductive behavior is to be explained using the example of a species from the family of the Machilidae: Petrobius maritimus. The male of the cliff divers wet spun yarn itself produced with 1-5 drops of sperm. By drumming signals with the Maxillarpalpen the Paarungswilligkeit the female is then achieved. Then the female is done with the help of Maxillarpalpen to the drop of sperm, which are then absorbed by the genital opening.

System

Machilidae and are Meinertellidae be sister and thus form a monophyletic group, namely the cliff divers ( = Archaeognatha ). The cliff divers branch off at basal position in the phylogenetic tree of insects. The cliff divers are probably the sister group of the Dicondylia which have two condyles of the mandibles. The Dicondylia include not only the small fish ( Zygentoma ) all flying insects ( pterygota ).
