| abstract | An online database on the taxonomy of Tydeoidea is described and is available on the Wikispecies platform at https://species.wikimedia.org/wiki/Tydeoidea. It counts 1 324 records or pages, 724 records for the Tydeidae, 334 for the Ereynetidae, 203 for the Iolinidae and 63 for the Triophtydeidae. For each taxon are detailed the parent taxa as well as the child taxa which are listed. A nec subsection lists names of child taxa that are not recommended. Subjective and objective synonymies as well as homonymies are given for each taxon. Notes provide historical aspects of past studies. The type locality and habitat of the name-bearing type and its repository are added for the nominal species-group taxa. Fossil species, species inquirendae and nomina nuda are also reported. References and external links end up a record. Tetranychus viburni Koch is resurrected from synonymy with Tetranychus urticae Koch and placed in Tydeidae; it might be a senior synonym of Tydeus goetzi Schruft. Replacement names are provided for Aureliania and Tydides (homonymy) and for Paratydaeolus clavatus (synonymy). |
