Scolopendrellidae

Scolopendrellidae is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Scolopendrellidae rather than just read about it. In short: Scolopendrellidae is a family of pseudocentipedes in the class Symphyla. This family includes nine genera and at least 97 described species.

Key takeaways

Scolopendrellidae belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Scolopendrellidae to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Scolopendrellidae from memory before moving on to harder problems.

Reference excerpt

Scolopendrellidae is a family of pseudocentipedes in the class Symphyla. This family includes nine genera and at least 97 described species. This family has a subcosmopolitan distribution.

Description Symphylans in this family usually measure less than 4 mm in length. In this family, the head and neck are not distinctly separated. The antennae usually have fewer than 20 articles and feature two types of setae, with only small branched sensory organs on the most distal segment. The tergites range from 15 to 24 in number. The first tergite can be well developed or quite reduced in size. The area at the end of each of the cerci (spinnerets) is usually striated (i.e., striped). In this family, the first pair of legs is reduced in size and is never more than half as long as the next pair. In some species, the first leg pair is rudimentary or absent. In the genus Symphylella, for example, these legs are vestigial and reduced to small protuberances, and in the genus Ribautiella, these legs are only rudimentary. In this family, the styli at the base of the legs are poorly developed or rudimentary.

Fossils Fossils of symphylans are rare and limited to specimens found in amber. This family includes only one species described from a fossil: Symphylella patrickmuelleri, which was discovered in Myanmar and described based on a juvenile found in Burmese amber from the Cenomanian age of the mid Cretaceous period. This specimen is the only fossil representative of this family and dates from about 99 million years ago.

Genera and distribution This family includes the following nine genera:

Geophilella Ribaut, 1913 Neosymphyla Edwards & Belfield, 1967 Parviapiciella Mas & Serra, 1993 Remysymphyla Aubry & Masson, 1952 Ribautiella Brölemann, 1926 Scolopendrella Gervais, 1839 Scolopendrellopsis Bagnall, 1913 Symphylella Silvestri, 1902 Symphylellina Brölemann, 1931 The genus Symphylella is the largest in this family, with at least 61 species, followed by the genus Scolopendrellopsis, with at least 17 species. The genera Symphylella and Scolopendrellopsis have subcosmopolitan distributions. The genus Ribautiella is the third largest in this family, with nine species, and has a broad distribution in the Neotropical and Afrotropical realms. The genus Remysymphyla is smaller, with only four species, and has a broad distribution in the Palearctic, Afrotropical, and Indomalayan realms. The genus Geophilelia includes only two species and is limited to the Nearctic and Palearctic realms. The other four genera are monotypic and have more limited distributions, with Neosymphyla in the Afrotropical realm, Parviapiciella in the Palearctic realm (in the Mediterranean region, North Africa, and central Europe), Scolopendrella in the western Palearctic realm, and Symphylellina in the Loyalty Islands.

Worked examples

Example 1 — a first encounter with Scolopendrellidae

Start with the simplest possible case. Write down what Scolopendrellidae claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Scolopendrellidae before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Scolopendrellidae ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Scolopendrellidae

In research: Scolopendrellidae appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Scolopendrellidae in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Scolopendrellidae is common in secondary-school and first-year university syllabi. It links to neighbouring topics Myriapod families, Myriapod stubs, Symphyla, so understanding it makes those chapters shorter.
In everyday life: Look for Scolopendrellidae outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
