Phylum : Arthropoda (with several classes) Class : Insecta (Hexapoda) The subclass Apterygota has 4 orders namely 1. The nymphs (younger stages) go through little or even no metamorphosis, hence they … For instance Slaters, Cheesybugs and Woodlice are all different names for the same animal, in different parts of the world. The class Insecta has two subclasses viz., Apterygota and Pterygota. The Insects (Class Insecta) are divided into a number of Orders. The classification of the Apterygota changed over time.

The Apterygota are wingless insects and the subclass contains two Orders: Archaeognatha (Order: Microcoryphia) Three-pronged bristletails (Order: Thysanura) Other names for (or types of) Apterygota include: Wingless insects. Characteristics. This group is arguably the largest and most complex of all the orders of insects and they seem to be only distantly related to the other endopterygotes. 11-segmented, but last segment often reduced. While the first three groups formed a monophyletic group, the Entognatha, distinguished by having mouthparts submerged in a pocket formed by the lateral and ventral parts of the head capsule, the Thysanur… The groups without flight are in the Apterygota. winged insects. Sous-embranchement Hexapoda Blainville , 1816 Classes de rang inférieur Collembola - les collemboles Diplura - les diploures Insecta - les insectes Protura - les protoures Les Hexapodes (Hexapoda) constituent un sous-embranchement qui regroupe principalement les insectes et d'autres arthropodes à trois paires de pattes: les protoures , diploures et collemboles , … Order – Protura e.g. External Structure of Insects, 3. Hmyz (Insecta) je třída šestinohých živočichů z kmene členovců, kteří mají tělo rozdělené do tří článků (hlava, hruď a zadeček).Pro všechny druhy je charakteristické, že mají tři páry nohou, většinou mají složené oči, tykadla a jsou jedinými členovci, kteří umějí aktivně létat. Their first known occurrence in the fossil record is in the Rhynie chert of the Devonian period, ~400 million years ago. Their mouthparts are entognathous, meaning that they are retracted within the head, unlike the insects. Taxonomist A.D. Imms proposed a classification of insect. Example- Bee, Mosquito and Cockroach. ... Apterygota. Silverfish are among the oldest species of animals on Planet Earth. The Apterygota, which formerly included the other primitively wingless insects currently placed in the class Entognatha, are now restricted to the two orders Archaeognatha and Zygentoma, which in turn were formerly united as the Thysanura. Mandibles are articulated at single point. Volume 46, Issues 3–4, 2002, Pages 373-384. The classification of insects into various orders is based on the presence or absence of wings and their venation, type of mouth parts, type of metamorphosis and characteristics of antennae and tarsi. Silverfish. Silver fish 5. Some 9,50,000 species or more are known. They are the Diplura, Thysanura, Collembola and Protura. class insecta. Family: Meinertellidae. Apterygota Pterygota 1.

Insect classification can look complicated, in ordinary English not everybody uses the same names for the same insects. Prepare data source for list by defining array of string for items names and array of integer for images. They have an exoskeleton made up of Chitin and jointed appendages used for locomotion, feeding and other purposes. With the advent of a more rigorous cladistic methodology, the subclass turned out to be paraphyletic. Entomol. Sub – Class Apterygota. a forked-jumping organ found on the 4th abdominal segment of the Collembola. e.g. ARTHROPOD CLASSIFICATION 2. Some 9,50,000 species or more are known. For example, if the class Hexapoda is divided to subclasses Apterygota (primarily wingless insects) and Pterygota (winged insects) (see V-1: Classifications of Hexapoda I), we can say about the subclass Apterygota, that it is paraphyletic and ancestral for Pterygota, or what is the same, Apterygota is more primitive than Pterygota. Mandibular articulation in head is The class hexapoda is divided in two subclasses: 1. They are insects which have never had wings at any time in their evolutionary history. Apterous.

There are about 250 species found throughout the world Class: Insecta Apterygota Order: Archeognatha Family: Machilidae. Silverfish are closely related to the Rhyniognatha, the world’s oldest known insect. 42867, whereby presence of Apterygota in layer with depth 0-10cm was 71.32%, and in layer with depth 10-20cm was 28.68%. The group Apterygota is not a clade; it is paraphyletic . The primary characteristic of the apterygotes is they are primitively wingless. While some other insects, such as fleas, also lack wings, they nonetheless descended from winged insects but have lost them during the course of evolution. • Thorax is the centre of locomotion with, 3 pairs of five jointed legs and two pairs of wings. The nymphs (younger stages) go through little or even no metamorphosis, hence they … Adults possess one or more pairs of pregenital appendages. The name Apterygota is sometimes applied to a subclass of small, agile insects, distinguished from other insects by their lack of wings in the present and in their evolutionary history.Their first known occurrence in the fossil record is during the Devonian period, 417–354 million years ago.. These are grouped together into two sub-classes called the Apterygota (wingless insects) and the Pterygota (winged insects) - for further information on Classes, Orders and Sub-classes see the Classification section. Segment 2 – 7 each contain single undivided ventral sclerite or sternite; and pair of coxopodites. Some insects are secondarily wingless. Step 4. Output: Apterygota Orders Screen. Ectognathous mouthparts, with mandibles attached at one point. CLASSIFICATION OF FISHES (Suneel Singh) Fishes have been classified in different ways from time to time. Springtails, Snow fleas 3. These apterygote orders share several “primitive” characteristics with crustaceans and non-insect hexapods. Order 1: Diplura.
