The Infraphylum Atelocerata is a member of the Subphylum Mandibulata. Here is the complete "parentage" of Atelocerata:
- Domain: Eukaryota
Whittaker & Margulis,1978 - eukaryotes
- Kingdom: Animalia
C. Linnaeus, 1758 - animals
- Subkingdom: Bilateria (Hatschek, 1888) Cavalier-Smith, 1983 - bilaterians
- Kingdom: Animalia C. Linnaeus, 1758 - animals
The Infraphylum Atelocerata is further organized into finer groupings including:
- Superclass (2): Myriapoda · Panhexapoda
- Series (10): Aculeata · Bombyciformes · Cossiformes · Gracillariiformes · Hesperiiformes · Limacodiformes · Papilioniformes · Parasitica · Saturniiformes · Tineiformes
- Class (8): Chilopoda · Diplopoda · Entognatha · Euglenoidea · Insecta · Pauropoda · Secernentea · Symphyla
Centipedes (from Latin prefix , "hundred", and pes, pedis, "foot") are arthropods belonging to the class Chilopoda of the subphylum Myriapoda. They are elongated metameric animals with one pair of legs per body segment. Despite the name, centipedes can have a varying number of legs from under 20 to over 300. Centipedes have an odd number of pairs of legs, e.g. 15 or 17 pairs of legs (30 or 34 legs) but never 16 pairs (32 legs). A key trait uniting this group is a pair of venom claws or forcipules formed from a modified first appendage. Centipedes are a predominantly carnivorous taxon.:168 [more]
Millipedes are arthropods that have two pairs of legs per segment (except for the first segment behind the head which does not have any appendages at all, and the next few which only have one pair of legs). Each segment that has two pairs of legs is a result of two single segments fused together as one. Most millipedes have very elongated cylindrical bodies, although some are flattened dorso-ventrally, while pill millipedes are shorter and can roll into a ball, like a pillbug. [more]
Insects (from Latin , a calque of Greek ??t???? [?ntomon], "cut into sections") are a class of living creatures within the arthropods that have a chitinous exoskeleton, a three-part body (head, thorax, and abdomen), three pairs of jointed legs, compound eyes, and two antennae. They are among the most diverse groups of animals on the planet, including more than a million described species and representing more than half of all known living organisms. The number of extant species is estimated at between six and ten million, and potentially represent over 90% of the differing metazoan life forms on Earth. Insects may be found in nearly all environments, although only a small number of species occur in the oceans, a habitat dominated by another arthropod group, the crustaceans. [more]
Pauropods are small, pale, centipede-like arthropods. They form the order Pauropodina, belonging to the monotypic class Pauropoda. About 500 species in four families are found worldwide, living in soil and leaf mould. They look rather like centipedes, but are probably the sister group to millipedes. The name is derived from the Greek roots pauro "small" and podo "foot". [more]
Secernentea are the main class of nematodes, characterised by numerous and an excretory system possessing lateral canals. Like all nematodes, they have no circulatory or respiratory system. [more]
Symphylans, also known as garden centipedes or glasshouse symphylans, are soil-dwelling arthropods of the class Symphyla in the subphylum Myriapoda. Symphylans resemble centipedes, but are smaller and translucent. They can move rapidly through the pores between soil particles, and are typically found from the surface down to a depth of about 50 cm. They consume decaying vegetation, but can do considerable harm in an agricultural setting by consuming seeds, roots, and root hairs in cultivated soil. [more]
At least 25 species and subspecies belong to the Class Symphyla.
