Summary
A new replacement name is proposed for the spider genus Ransonia (Arachnida: Araneae) due to a name conflict with a hydrozoan genus. This ensures taxonomic clarity for the Malagasy Pisauridae family.
Area of Science:
- Zoology
- Taxonomy
- Arachnology
Background:
- The spider genus Ransonia (Arachnida: Araneae) was established in 1979 for a species endemic to Madagascar.
- This genus name is preoccupied by Ransonia (Hydrozoa: Trachymedusae), a genus of cnidarians established in 1947.
- The spider genus Ransonia Blandin, 1979 is a junior homonym of Ransonia Kramp, 1947.
Purpose of the Study:
- To propose a new substitute name for the preoccupied spider genus Ransonia Blandin, 1979.
- To comply with Article 60 of the International Code of Zoological Nomenclature.
- To resolve taxonomic ambiguity between the spider genus and the hydrozoan genus.
Main Methods:
- Identification of a homonymous genus name in zoological nomenclature.
- Review of the International Code of Zoological Nomenclature (Article 60).
- Proposal of a new replacement name for the junior homonym.
Main Results:
- The spider genus Ransonia Blandin, 1979 is a junior homonym.
- A new substitute name is required for the spider genus Ransonia.
Conclusions:
- A new replacement name is proposed for the spider genus Ransonia Blandin, 1979.
- This action rectifies the homonymy and ensures taxonomic stability for the genus Ransonia (Araneae).

01:10Nomenclature of Aryl and Heterocyclic Amines
3.3K
The simplest aromatic amine is phenylamine, which contains an –NH2 functionality directly attached to an aromatic ring. The name aniline is designated for this skeleton. As shown in Figure 1, the common names of the functionalized anilines involve prefixes ortho-, meta-, and para- to indicate the substitution position. Different functionalized aniline derivatives also have notable trivial names.

01:23Nomenclature of Aromatic Compounds with a Single Substituent
10.9K
Benzene is the simplest aromatic hydrocarbon or arene. The IUPAC names for simple monosubstituted benzene derivatives are derived by adding the substituent's name as a prefix to the parent benzene. For example, halobenzene, where the halogen could be fluoro (F), chloro (Cl), bromo (Br), and iodo (I).

01:11Nomenclature of Aromatic Compounds with Multiple Substituents
11.2K
When more than one substituent is present on the benzene ring, the IUPAC nomenclature depends on the number of substituents present.
For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...

3.6K
During the development of a new pharmaceutical, the manufacturer initially assigns a code name to the drug. Once approved, the drug receives a United States Adopted Name (USAN)—a generic, nonproprietary designation. Upon being listed in the United States Pharmacopeia, this nonproprietary name becomes the drug's official name. Additionally, the manufacturer assigns a proprietary name or trademark, which serves as the brand name under which the drug is marketed. It is worth noting that...

01:11Common Names of Aldehydes and Ketones
5.4K
Some common aldehydes and ketones are popularly known by their common names used historically and predate the IUPAC nomenclature.
Common names of aldehydes are derived from the names of their corresponding acid. For instance, the two-carbon aldehyde–acetaldehyde derives its name from the corresponding acid–acetic acid. Similarly, formaldehyde derives its name from formic acid and benzaldehyde from benzoic acid.
Aliphatic ketones are named by suffixing the word “ketone” to the...

02:39Predator-Prey Interactions
22.1K
Predators consume prey for energy. Predators that acquire prey and prey that avoid predation both increase their chances of survival and reproduction (i.e., fitness). Routine predator-prey interactions elicit mutual adaptations that improve predator offenses, such as claws, teeth, and speed, as well as prey defenses, including crypsis, aposematism, and mimicry. Thus, predator-prey interactions resemble an evolutionary arms race.
