Where this source is used
Cited by 18 statements
Abdomen
- The hind part of the body, made of five segments and a small end piece. It carries the collophore, the retinaculum and the furca. (at Introduction, external anatomy)
Accepted name
- The name a reference work currently treats as correct for a taxon. Two works can disagree, so this site shows which one it follows. (at Introduction)
Antenna
- One of the two feelers on the head. Each has four main segments, and some species divide these into many smaller sections. (at Introduction, external anatomy)
Claw
- The claw at the tip of each leg, called the unguis. Many springtails also have a smaller inner claw or a small pad beside it. (at Introduction, external anatomy)
Collembola
- The antennae have four main segments. Segments may be split again into small rings, so some species have clearly jointed antennae and others do not. (at Introduction, external anatomy and morphology)
Collembola
- The class of animals called springtails. They are small, wingless and six-legged, and their mouthparts sit inside the head. Most carry a folded jumping organ under the body. (at Introduction)
Collophore
- A small tube on the underside of the first abdominal segment with two soft bulbs that can be pushed out. It helps the animal keep its water balance and cling to smooth surfaces. (at Introduction, etymology)
Furca
- The forked jumping organ folded under the body. A base piece (manubrium) carries two arms (dentes), and each arm ends in a small tip (mucro). Some springtails have a short furca or none. (at Introduction, external anatomy)
Habitus
- The overall shape and look of an animal, such as slender, plump or globular. It is the first thing to judge, before any fine detail. (at Introduction, external anatomy)
Ocellus
- One of the single eyes that together make up the eye on each side of the head. A side carries at most eight, and some springtails have none. (at Introduction, external anatomy)
Postantennal organ
- A small sensory organ just behind the base of each antenna. You need a microscope to see it, and some springtails do not have one. (at Introduction, external anatomy)
Proisotoma minuta
- The name Podura in Blue Podura does not point to the genus Podura or the family Poduridae. This species belongs to the family Isotomidae. (at Isotomidae)
Pseudosinella violenta
- Systems differ on the family of Pseudosinella and its relatives. The working hierarchy here follows the Checklist of the Collembola and puts the genus in Lepidocyrtinae, within Paronellidae. Another system may place it elsewhere. (at Lepidocyrtinae)
Retinaculum
- A small forked clasp under the third abdominal segment. It holds the folded furca in place until the springtail jumps. (at Introduction, external anatomy)
Seira dowlingi
- On the Checklist of the Collembola the old name Drepanocyrtus dowlingi Wray, 1953 sits in the synonym list of Seira musarum Ridley, 1890. The same page carries photographs captioned Seira dowlingi from Brazil, the USA and China, credited to a 2019 study by Cipola and colleagues. Whether Seira dowlingi is a valid species is therefore open on this site. (at Seirinae, Seira musarum synonyms and image captions)
Symphypleona
- Symphypleona have a round, bead-like body. The first four abdominal segments are fused into one large rounded mass, so the trunk segments cannot be told apart. (at Introduction, external anatomy and morphology)
Thorax
- The three body segments behind the head. Each one carries a pair of legs. (at Introduction, external anatomy)
Trunk
- The body behind the head. It is the thorax and the abdomen together. (at Introduction, external anatomy)
