Symphypleona
The order Symphypleona is one of the three main groups of springtails (Collembola), tiny hexapods related to insects. When the springtails were still believed to be an order of insects, the Symphypleona were ranked as a suborder. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical, and usually have long antennae. The Poduromorpha, by contrast, always have short legs and a plump body, but more oval in shape than the Symphypleona. The Entomobryomorpha are the slimmest springtails, some with long and some with short legs and antennae, but always with a very slender body. Systematics The Symphypleona order was previously suggested to also contain family Neelidae, as a very apomorphic relative in the Sminthuridae superfamily. Phylogenetic studies however suggest Neelidae to be the only family of Neelipleona order.Gao, Yan; Bu, Yun & Luan, Yun-Xia (2008): Phylogenetic Relationships of Basa ...

Springtail
Springtails (Collembola) form the largest of the three lineages of modern hexapods that are no longer considered insects (the other two are the Protura and Diplura). Although the three orders are sometimes grouped together in a class called Entognatha because they have internal mouthparts, they do not appear to be any more closely related to one another than they are to all insects, which have external mouthparts. Collembolans are omnivorous, free-living organisms that prefer moist conditions. They do not directly engage in the decomposition of organic matter, but contribute to it indirectly through the fragmentation of organic matter and the control of soil microbial communities. The word ''Collembola'' is from the ancient Greek "glue" and "peg"; this name was given due to the existence of the collophore, which was previously thought to stick to surfaces to stabilize the creature. Some DNA sequence studies suggest that Collembola represent a separate evolutionary line fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sminthuridae
Sminthuridae is a family of springtails of the order Symphypleona. Sminthurids are commonly referred to as globular springtails. Description Like other Symphypleona, Sminthuridae are globular in shape and have a furcula that allows them to jump. Members of this family have four-segmented antennae in which the basal segment is short and the rest successively increase in length. The terminal antennal segment has about 20 whorls of hairs and is divided into numerous subsegments. Sminthuridae also have well-developed tracheae. The dens has many setae, unlike in Mackenziellidae where it has 3 setae. Females have subanal appendages. Ecology Sminthuridae occur in surface litter layers, on vegetation and in tropical forest canopies. They may be collected using Tullgren funnels or pitfall traps, or by sweeping through grass with a pan. Additionally, Sminthuridae is one of the springtail families that includes species living in freshwater. List of genera Ten genera are placed ...

Poduromorpha
The order Poduromorpha is one of the three main groups of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily Poduroidea. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical and the abdominal segments are not visible. Both Entomobryomorpha and Poduromorpha are long springtails with six visible abdominal segments. While Entomobryomorpha have the first thorax segment reduced, Poduromorpha retain all three. The Poduromorpha also tend to have short legs and a plump body, but more oval in shape than the Symphypleona. Their name means ‘foot tail formed’, deriving from their short, flat, furcula. Systematics The Poduromorpha were, as Poduroidea, united with the Entomobryomorpha (then called Entomobryoidea) in a group called "Arthropleona", but this has more recently turned out to be paraphyletic. Actually the Entomobryomorpha, the P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Allacma Fusca
''Allacma fusca'' is a species of springtail. This species is endemic to western areas of Continental Europe and the British Isles, where it lives in the surface layers of the soil in moist habitats such as among leaf litter. Description ''Allacma fusca'' is a large species of springtail with a dark brown globular abdomen; adults reach a length of around . There is often a "snowflake"-like marking on the abdomen, which is most noticeable in paler coloured individuals. The mouthparts are internal, and the head bears a pair of antennae, two groups of eyespots known as "composed eyes" and a pair of small post-antennal organs. The setae (bristles) on the third antennal segment are unequal in length, some being much longer than others, and the fourth antennal segment is divided into sixteen sub-segments. There are three thoracial segments, each bearing a leg, and five abdominal segments. The fourth abdominal segment bears an organ known as a "dens", and at the tip of this is a str ...

Neelipleona
Neelipleona is a name given to some hexapods of the subclass Collembola (springtails). While their taxonomic rank remains broadly settled as family Neelidae, Neelipleona has been described at order or suborder rank. Eyes are absent. Taxonomic rank Many authors consider the "Neelipleona" Symphypleona of the superfamily Sminthuroidea, family Neelidae.See references in Haaramo (2008) However, in other accounts, Neelipleona are either a distinct order from the three less controversial Springtail orders (Entomobryomorpha, Poduromorpha The order Poduromorpha is one of the three main groups of springtails (Collembola), tiny hexapods related to insects.

Entomobryomorpha
The Entomobryomorpha are one of the three main groups ( order) of springtails (Collembola), tiny hexapods related to insects. This group was formerly treated as a superfamily, the Entomobryoidea. They can be best distinguished from the other springtail groups by their body shape. The Symphypleona are very round animals, almost spherical. The Poduromorpha are also very plump but have a more oval shape. The Entomobryomorpha, by contrast, contain the slimmest springtails. They either have short legs and antennae, but their long bodies set them apart, or long legs and antennae, as well as well-developed furculae; these are the most characteristic members of the order. Systematics The Entomobryomorpha were, as Entomobryoidea, united with the Poduromorpha (then called Poduroidea) in a group called "Arthropleona", but this has more recently turned out to be paraphyletic. Actually, the Entomobryomorpha, the Poduromorpha, and the third springtaill lineage – the Symphypleona – a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
